  • Advanced Air Mobility Market Outlook Charged with Opportunity - aircraft worker - Parker AerospaceFor decades, futurists have been dreaming of “flying cars” that are easier and nimbler to operate than a helicopter and accessible to everyone. Today, many aerospace technologies are coming together helping numerous companies develop small passenger electric aircraft as soon as 2023.

    It’s no secret that Advanced Air Mobility (AAM) is going to be a hotly contested market with legacy aircraft builders, nimble startups, and original equipment manufacturer (OEM) systems providers clarifying their vision of the future. This new market aims to transport passengers and cargo at lower altitudes through urban, suburban, and regional landscapes. Aircraft that will meet these needs will utilize more- or all-electric technologies. 


    Vast possibilities, by any measure

    Advanced Air Mobility Market Outlook Charged with Opportunity - Flying Taxi - Parker AerospaceAccording to a 2020 Roland Berger study on Urban Air Mobility (UAM), a submarket of AAM, “the passenger UAM industry will generate revenues of almost $90 billion a year, with 160,000 commercial passenger drones plying the skies.” Further, Morgan Stanley Research projects that the UAM market could grow to $1.5 trillion by 2040. 

    Even the most conservative forecasts indicate the AAM market has huge potential as evidenced by the hundreds of vehicles in development.


    AAM is evolving toward reality

    In early 2021, Air One, the world’s first airport for electric aircraft, was launched in Coventry, England by Urban Air Port, a subsidiary of sustainable tech company small (Six Miles Across London Limited) in partnership with Hyundai Motor Company, Coventry City Council, and the UK government. 

    As technology evolves, infrastructure is built, and the regulatory/certification requirements established, AAM vehicles will take different forms:

    • Hybrid electric vehicles will be using on-board electrical generating equipment, such as hydrogen power plants or small gas turbines, to generate the electricity needed for propulsion as well as for other systems like flight controls, environmental controls, accessories, and electric braking. Hybrid aircraft may be tasked with shorter regional routes – as opposed to short-hop intra-urban routes – and could be fixed-wing types that take off and land traditionally, or those that takeoff and land vertically. Such hybrid vehicles, which have the potential of significantly reducing emissions, are bridging the gap between today’s conventionally powered aircraft and all-electric ones.
    • All-electric vehicles will primarily utilize rechargeable battery packs for flight energy. These aircraft will likely be of the electric vertical takeoff and landing (eVTOL) type, using distributed electric propulsion systems where the propulsive motors are distributed around the vehicle in proximity to the rotors that provide lift, forward motion, and flight control.

    MEA: a pathway to an all-electric future

    Advanced Air Mobility Market Outlook Charged with Opportunity - UAM - Parker AerospaceMore-electric aircraft (MEA), which have been in production for over a decade, utilize electric power for all non-propulsive systems. The trend toward more-electric aircraft has been driven by the desire for improvements in aircraft weight, fuel efficiency, emissions, life-cycle costs, maintainability, and reliability.

    Technology advancements in the areas of electric motors, motor controllers and inverters, electromechanical actuators (EMAs), and thermal management equipment are providing the building blocks that enable development of systems for more-electric aircraft.

  • Solid-State Power Controller Empowers Future Aircraft - conventional vs more electric aircraft - Parker AerospaceThe future of air travel is evolving beyond fossil fuels with hybrid electric and all-electric aircraft leading the way. The growing need for low emissions and carbon neutrality has created a new focus on more electric aircraft (MEA), as aircraft original equipment manufacturers (OEMs) look to satisfy the growing needs of travelers while achieving the environmental goals being mandated around the world.

    Power for all systems on conventional aircraft today is derived primarily from jet engines, fueled, of course, by fossil fuels. Engine gearbox-driven generators provide power for standard electrical equipment like avionics, lighting, and general cabin power. High-pressure engine bleed air is used to drive pneumatic systems such as cabin pressurization, anti-icing, and air conditioning. The engine gear box also drives hydraulic pumps for flight controls, landing gear, braking systems and door actuation as well as mechanical systems such as oil and fuel pumps. Parker Aerospace has a deep pedigree stretching back decades with sub-systems and components in conventional engines. 

     

    Solid-State Power Controller Empowers Future Aircraft - conventional aircraft engine - Parker Aerospace


    Moving towards more electric aircraft

    The evolution to MEA changes the way these systems are implemented. Whether it’s a more electric aircraft with jet engines, a hybrid electric, or a fully electric aircraft, mechanically-driven pumps for hydraulics, pneumatics, oil, and fuel will be replaced with fully electric pumps and actuators for everything including flight surface controls, environmental systems, and braking. 

    Initially, gas-powered engines will still drive the electric generators for these systems. Ultimately, gas turbine engines may be replaced entirely with fully electric motors and batteries. This migration will start small, with commuter transports and urban air mobility platforms first reaching the market.

    Solid-State Power Controller Empowers Future Aircraft - More Electric Aircraft Engine - Parker Aerospace

    Migration from hydraulic and pneumatic energy to electric energy requires improved power-handling capability and efficiency. System voltages for MEA will climb from 28VDC and 115VAC to upwards of 1,000VDC. This power will be delivered by a complex combination of generators and batteries and requires a highly advanced and flexible electrical distribution system capable of managing system needs.


    Developing improved solutions for new demands

    Along with the increase in demand and capacity, the potential for significant damage during short or overload conditions must be recognized. For example, a 270V Li-Ion battery can deliver more than 2,000 amps into a short in a matter of microseconds. The typical electrical interfaces on today’s aircraft consist of mechanical relays and contactors, which are not fast enough to prevent fault propagation, and may even fuse during a fault event. This drives a need for an effective solution for high voltage, high-power buses with enhanced capability.

    To answer that call, Parker Aerospace’s Fluid Systems Division has been developing a modular solid-state power controller (SSPC) for use as a standalone unit that is an electronic replacement for a relay or contactor. As part of a larger electrical distribution system, multiple SSPCs can be configured into a solid-state electrical distribution unit (SSEDU). Think of an SSPC as an individual circuit breaker whereas the SSEDU would be the entire circuit breaker box containing multiple breakers. An SSEDU can be configured with two or more SSPCs, with each SSPC being an individually controlled channel.

    Utilizing advanced silicon carbide technology, Parker’s SSPC design is a modular architecture that yields the potential to accommodate multiple platform applications without costly redesigns and qualifications. Some features include:

    • High-speed, high-efficiency, high-power density per channel.
    • High-speed fault mitigation and bus reconfiguration.
    • Programmable I2T fault protection.
    • Inrush current mitigation (for high capacitive input loads).
    • Low RDSon to maximize efficiency.
    • Bi-directional and bi-polar SSPC options.
    • Discrete input or communication bus control.
    • Support for ARINC 429, Mil-Std-1553, CAN bus & others. 

    Multiplying the benefit from solid-state power controllers

    Solid-State Power Controller Empowers Future Aircraft - First Generation SSPC - Parker AerospaceAn individual SSPC can be programmed and coordinated with other SSPCs to provide staggered power on/off configurations when used in a multi-channel configuration. Power sequencing, source and load isolation, power routing, and bi-directional flow for battery charge/discharge, can all be configured in the same SSEDU. Voltage, current, temperature and other performance and fault data is available for each SSPC.

    The Parker Aerospace modular SSPC design provides benefits beyond the technical specifications. The initial concept was to provide the protection and control in a format that would allow scalability and flexibility in an electrical distribution system implementation. Taking advantage of the common SSPC design allows for:

    • Reduced application non-recurring engineering (NRE) and development time
    • Reduced platform certification cost and time.
    • Certification by similarity of sub-components across applications and platforms.
    • Reduced reliance on key components/suppliers.
    • Increased flexibility to integrate new technologies.
    • Ability to use the same part number across multiple applications.

    Parker has completed testing of a first-generation, eight-channel SSEDU, with each channel configured for 270VDC and handling loads from 20 amps to 150 amps. The capability demonstrated included programmed and manual switch control, bolted short fault mitigation, startup and operational overcurrent protection, thermal efficiency with continuous loads, and bi-directional power flow on individual channels.

    Solid-State Power Controller Empowers Future Aircraft - Second Generation SSPC - Parker AerospaceCurrent development on the second-generation SSPC will culminate with a two-channel unit in a more compact, thermally efficient, and lighter unit. This fully capable demonstrator will provide an example of how the Parker Aerospace SSPC and SSEDU can be utilized for multiple applications and configurations requiring the control, protection, and flexibility required to satisfy the needs of the new generation of more electric aircraft.

  • Exotic Metals Aircraft Services Provides Support Across all Aerospace - EMFAS team member finishing a repair - Parker AerospaceWhen people think of the Exotic Metals Forming Division, a division of Parker Aerospace, most think of manufacturing new parts for commercial and military aircraft programs. Many don’t know what happens to new hardware once it leaves the factory and is installed on new aircraft. For the Exotic Metals Forming Aircraft Services (EMFAS) team members, this is where the story begins.


    In an ideal world, components from aerospace manufacturers — like pneumatic ducts, auxiliary power unit mufflers, engine exhaust plugs, nozzles, and other sheet metal parts — would last the lifetime of an airplane. A myriad of things that happen during the daily operation of an aircraft can impact this goal. For example, a baggage cart bangs into the engine exhaust plug. A duct is inadvertently dented during an engine change. A bellows flex joint prematurely wears. Or a technician accidentally damages a part. That’s where aftermarket services are critical to get planes back in the air. And that is one of the reasons Parker Aerospace acquired Exotic Metals in 2019


    Serving the world’s airline fleets

    Exotic Metals Aircraft Services Provides Support Across all Aerospace - EMFAS team member removing rivets - Parker AerospaceAn idle aircraft is an expensive and complex reality for airlines trying to serve thousands of people. When such an event occurs, the EMFAS team delivers on its mission to serve airline customers and keep their fleet of aircrafts doing what they are designed to do: move people and goods as seamlessly and safely as possible.


    Exotic Metals Aircraft Services Provides Support Across all Aerospace - weld repairs on a 737 nozzle - Parker AerospaceEMFAS team members work in a dynamic environment. Every day brings new adventures, issues, customers, and people. These technical experts find it rewarding to help customers solve problems, develop relationships, and work with people from nearly every continent.  

     


    When are you likely to recommend?

    Exotic Metals Aircraft Services Provides Support Across all Aerospace - Operator removing oxidation from an engine duct - Parker AerospaceMost service businesses are built on relationships. Customers consider a company only as good as its last order. EMFAS views itself as a service business rather than a company that manufactures a product. There are no long-term contracts and no ownership of the intellectual property on the parts they repair so they must perform at the highest level every time. 

    How often have you gone to the same restaurant, had a good experience, and then the next time the service and food are terrible? One bad experience might keep you from ever going back. It works the same way with the aircraft services business. One bad experience can cost a customer’s business forever.

  • Elevating Flight With Decades-Strong Aerial Refueling Solutions- Aerial Refueling - Parker AerospaceWith an increased focus on strengthening United States military capabilities for the 21st century, Parker Aerospace takes pride in having a long history supporting the country’s defense endeavors around the world with flight-critical components. One of Parker’s most essential product lines for military aircraft is its aerial refueling equipment.  


    In-flight refueling couplers, nozzles, receptacles, and test kits from Parker Aerospace’s Fluid Systems Division represent today’s leading edge in design, performance, and durability. 

    Elevating Flight With Decades-Strong Aerial Refueling Solutions - Receptacle Stacks - Parker AerospaceThe division produces two standard systems for aerial refueling: 

      • Boom nozzle and receptacle system

      • Probe-and-drogue system

    The boom nozzle and receptacle are the interface traditionally adapted for Air Force applications including strike aircraft, tankers and transports, while the probe-and-drogue are traditionally adapted for Navy/Marine strike aircraft and military trainers.

     

    Staying on target non-stop

    Elevating Flight with Decades Strong Aerial Refueling SolutionsAerial refueling is the process by which an aircraft is loaded with fuel mid-air while still in flight. The crucial operation allows military craft to fly prolonged maneuvers and reconnaissance missions. In some cases, our inflight refueling equipment has been incorporated into platforms derived from commercial aircraft. One noteworthy example is the Boeing 747-200 used for Air Force One.

     


    Elevating Flight With Decades-Strong Aerial Refueling Solutions - C5 large transport refueling - Parker AerspaceParker’s development of in-flight refueling equipment began more than 55 years ago with Lockheed Martin’s reconnaissance aircraft, the SR71 Blackbird (1964). Parker designed the aerial refueling receptacle for this historic aircraft. After advancing early variants of a universal aerial refueling receptacle slipway installation (UARRSI) for the development of the Rockwell B-1 Lancer and the Fairchild A-10 Thunderbolt, Parker’s expertise was again put to use on the refueling receptacle for another U.S. fighter jet.  In those early days of evolving aerial refueling solutions, Parker augmented its knowledge base through the strategic acquisition of Schultz Tool and Manufacturing in 1971 a company that had designed receptacles for the F-111 Aardvark, the C-5 Galaxy, and the A-7 Corsair II.  


    In 1997, Parker again advanced its air-to-air offerings and necessary ground test equipment by acquiring the aerial refueling product line from XAR Industries in California. The company had previously provided aerial refueling product designs for Lockheed Martin’s F-16, F-117, and F-22 as well as Universal Aerial Refueling Receptacle (UARRSI) variants.


    Building on the technologies and applications from Parker, Shultz and XAR, our teams developed a unique receptacle and slipway assembly for the B-2 program. Since this time, Parker has subsequently designed multiple derivatives of the UARRSI and application-specific receptacles for several programs including the F-22 and F-35 programs.

     

    Utah Air National Guard members from the 191st Air Refueling Squadron execute an air refueling mission from a KC-135 Stratotanker. A B-2 Spirit from the 509th Bomb Wing at Whiteman AFB, Missouri participated during this training mission. Video by Staff Sgt. Erin Mills.

     

    The multi-purpose UARRSI convenience and adaptability

    Elevating Flight With Decades-Strong Aerial Refueling Solutions - universal aerial refueling receptacle - Parker AerospaceIn 1976, Parker introduced an improved universal aerial refueling receptacle slipway installation (UARRSI) which has proven to be Parker’s most versatile piece of aerial refueling equipment. UARRSI adapts to aircraft that require a nozzle and receptacle-type apparatus. The unit features a lighted slipway and voice command functionality to facilitate the fuel transferring process. UARRSIs are used on military aircraft including the Boeing C-17, McDonnell Douglas KC-10, the Airbus A330 MRTT, and the Boeing GTTA, P-8A, and the 737 AEW&C E-7 Wedgetail. 

     
    Testing equipment within critical industry standards

    Elevating Flight With Decades-Strong Aerial Refueling Solutions - Aerial refueling testers - Parker AerospaceParker’s aerial refueling ground test kits are used to evaluate at the aircraft or component levels, along with the voice inter-communication capability. This testing function allows engineers to assess specific status modes (connect and disconnect), as well as alignment and engagement states of the equipment. Parker’s product line conforms to original equipment manufacturing (OEM) specifications, U.S. military standards, and additional requirements developed by the Aerial Refueling Systems Advisory Group (ARSAG) and other like agencies. 

     


    Supporting the next generation of aerial refueling

    Elevating Flight With Decades-Strong Aerial Refueling Solutions - next gen aerial refueling - Parker AerospaceThe future of in-flight refueling technology is now taking off in innovative directions, with a renewed emphasis on safety and efficiency.

  • Reducing Lead Times by Half Earns Praise from Customer GA-ASI - 030228-F-4928T-149 - Parker AerospaceWhat do you do when your production and maintenance, repair, and overhaul (MRO) teams are faced with unscheduled demand for new equipment and overhaul/repair services from a customer supporting the United States military? Especially when you are required to cut lead times in half? 

    The answer: collaborate with your customer, thoroughly analyze data, sharpen lean processes, and get creative with supply chain strategy to hit the target. Then, in this case, the customer recognizes the success of your efforts.

     

    GA-ASI MQ-9, Avenger, and Gray Eagle increasing landing cycles

    Reducing Lead Times by Half Earns Praise from Customer GA-ASI - GA-ASI MQ-9, Avenger, and Gray Eagle - Parker AerospaceThe Aircraft Wheel & Brake Division (AWBD) of Parker Aerospace is the original equipment manufacturer (OEM) of wheels and brakes for the MQ-9, Avenger, and Gray Eagle remotely piloted aircraft (RPA) built by General Atomics Aeronautical Systems, Inc. (GA-ASI). Parker has enjoyed a long relationship with GA-ASI, providing not only OEM equipment but also overhaul and maintenance services for the fielded product. 

    As the GA-ASI aircraft have been called to fly more missions for the United States Air Force and Army, the number of aircraft landing and braking cycles and demand for new aircraft has grown. This growth led to a surge in order requirements which required AWBD to respond quickly and decisively to deliver in an aggressive time frame.

     

    Leaning forward to reduce production lead times

    Reducing Lead Times by Half Earns Praise from Customer GA-ASI - GA-wheel_1 - Parker AerospaceAs deployment of remotely-piloted aircraft grew, the need for new production wheels and brakes increased. Customer GA-ASI asked Parker to initially double, and ultimately triple, the number of deliveries per month to meet this requirement. 

    Lead times for new complex production orders, including the manufacture of forged and machined components plus assembly and testing, can take many months. Though not an uncommon reality for highly engineered products, the customer can encounter unscheduled demand due the aircraft’s success in the field. It was calculated that the greater need could only be met by cutting lead times by at least 50 percent.

    With this increase in demand and the timeframe required, it became apparent that a key impediment to success was the procurement of long-lead components, especially forged parts. Traditionally, the AWBD team would order forged parts when an order requiring them was in-house; this usually added weeks to the lead time. In the case with GA-ASI, AWBD’s supply chain team was able to adjust their forecast model and commit to carrying inventory for a number of long-lead parts, saving critical time.

     

    Using Lean principles to improve in-service support

    Reducing Lead Times by Half Earns Praise from Customer GA-ASI - MQ1 PREDATOR PREPARES FOR TAKEOFF - Parker AerospaceThe Parker team has continued to refine every aspect of its support to consistently meet customer expectations. With increased sorties comes increased demand for support, which is where Parker’s culture of continuous improvement can ensure operational capability and capacity. To keep up with increased demand, AWBD developed a prioritized overhaul schedule that was cost effective and ensured that necessary repairs were done on time. Additional AWBD kaizen events have yielded improved product flow through the repair station and cut turnaround times by nearly 70 percent.

     

    Collaboration key to improving lead time

    In both new production and field support, gaining a clear understanding of the hurdles to meet customer objectives was paramount to implementing change. And that took a concerted effort between the Parker and GA-ASI teams. Starting with forecasting data from the customer, the teams expanded their insight into which wheel and brake components needed to be ordered in advance and which would require repair or replacement. 


     Reducing Lead Times by Half Earns Praise from Customer GA-ASI- GA-ASI_Predator-B_Morning - Parker Aerospace“When we were faced with the need to shrink lead times and improve turnaround time for GA-ASI repairs, we naturally opened dialogue with the customer. We saw an opportunity for the Parker and customer teams to examine a broad range of data and meaningfully engage, aligning our systems while optimizing what we do and how we do it.”
    – Mark Harbison, key account manager, Parker Aerospace


     

    Sign of success: AWBD team acknowledged for its efforts

    In recognition of their commitment and work required to support increasing demand over multiple years, GA-ASI recognized Parker AWBD for its outstanding support. The Parker Aircraft Wheel & Brake team was presented with a banner from GA-ASI that thanked them for the outstanding support. The banner proudly hangs in the AWBD facility as a reminder of a job well done and the value in providing premier customer service.

  • eVTOL aircraft require comprehensive system-level thermal management - EVOT aircraft - Parker Aerospace There is growing, perhaps booming, commercial investment in electric vertical takeoff and landing (eVTOL) vehicles that will serve the new urban air mobility (UAM) aerospace market. Upstart and established companies are in a race to develop platforms that can bring about an age of civilian, commercial, and military mobility that enables users to break free of terrestrial limitations and move freely about the sky.

    Many aircraft for the new UAM market are in development independently, with large and small aerospace companies reaching out to our experts. Thermal management is a specific technology in demand where Parker Aerospace has deep experience and is now helping multiple UAM companies. 


    Accelerating takeoff

    eVTOL aircraft require comprehensive system-level thermal management - EVTOL aircraft - Parker Aerospace The United States Air Force recently launched the Agility Prime program, a “a non-traditional program seeking to accelerate the commercial market for advanced air mobility vehicles.” The program will enable the more rapid development, testing, and certification of eVTOL platforms – which Agility Prime calls “orbs” – for both civil and military use. The applications that Agility Prime cites for orbs include logistics and sustainment, medical evacuation, firefighting, disaster relief, search and rescue, and humanitarian relief operations.

    eVTOL aircraft require comprehensive system-level thermal management - Multi-model-EVOT aircraft - Parker Aerospace Going beyond its car-based ride-sharing beginnings, Uber is engaged in the civilian and commercial side of developing eVTOL aircraft – and the required infrastructure for aerial ride sharing – through its Uber Elevate team. Its aircraft development efforts are underpinned by strategic partnerships with several leading aircraft manufacturers. Recently Uber Elevate was acquired by competitor Joby Aviation with a goal to leverage the work of both companies.

    Further, eVTOL aircraft development is independently underway with a number of the world’s biggest names in aerospace.

    Transporting people with these vehicles creates a new mode of transportation that will connect between commercial air travel and automobiles. Yet moving goods with eVTOL vehicles, even with unmanned drones, may have a larger impact on our society. Cargo delivery drones require the same engineering and the same regulatory conditions, without people, however with the conventions needed and infrastructure to support regular flight. Widespread implementation of delivery drones will prove the systems and processes needed for like vehicle power management, communication, landing locations, and support infrastructure.  


    Distributed electric propulsion (DEP) is the system for eVTOL  

    eVTOL aircraft require comprehensive system-level thermal management - eVTOL-diagram- Parker Aerospace Among the propulsion systems being considered for eVTOL applications, distributed electric propulsion (DEP) has emerged as the likely configuration for UAM applications. DEP relies on multiple electric motor-driven rotor-type propulsors distributed across the aircraft to provide vertical lift, thrust, and flight control.

    Though DEP system-equipped vehicles will take advantage of the maneuverability afforded them by the technology, DEP systems pose unique challenges for the heat management of the electric motors, electric controllers, and battery packs necessary for their operation.

    The electric motors that drive the multiple rotors are arrayed around the aircraft, located in proximity to the rotors. These motors variably generate heat as they perform their propulsive duties, creating a need for effective thermal management to ensure optimal efficiency and motor life. Reducing weight is an important benefit of electric motors. Besides being environmentally friendly, the system for an electric motor has a dramatic weight reduction compared to traditional hydraulic motor systems. Lighter aircraft changes the flight profile and how the aircraft flies, allows for more passengers/cargo and provides more flexibility for other aircraft systems. 

    Electronic controllers are required to provide the digital commands that govern rotor speed and position, which enable an eVTOL’s ability to climb, descend, and navigate in airspace. These digital controllers take full advantage of the ongoing advancements in semiconductor manufacturing that permit more and more computational power in smaller footprints, giving rise to higher heat levels and heat densities that must, in turn, be removed from the controllers themselves.

    The battery packs that provide the electricity needed to power the motors generate heat as energy is released for use by the aircraft. There is significantly higher power demand placed on the batteries at takeoff and landing, which results in a variable thermal management requirement across the vehicle’s flight profile. The aircraft’s thermal management system must be responsive to this variability.

     

    Systems approach to eVTOL thermal management

    The key to successfully managing the heat generated by DEPs lies with a thermal management system (TMS) with the ability to collect heat in one location then transport it to a place where it can be safely rejected or dissipated. Such systems consist of three major elements:

    eVTOL aircraft require comprehensive system-level thermal management - Heat Collection - Parker Aerospace Heat collection components – such as liquid flow through cold plates or liquid-cooled enclosures    

     

     


    eVTOL aircraft require comprehensive system-level thermal management - Complex Tube Assemblies - Parker Aerospace Transport components – consisting of pipes, hose, connectors, and pumps  

     

     


    eVTOL aircraft require comprehensive system-level thermal management - Heat Rejection - Parker Aerospace Heat rejection/dissipation equipment – Heat rejection or dissipation equipment, or heat exchangers    

     

     


    eVTOL aircraft require comprehensive system-level thermal management - EVOT circuit - Parker Aerospace Controllers to coordinate and manage the system entire thermal dissipation of the system    
       
     

    Designing an efficient and size, weight, and power (SWaP) solution requires access to a wide-ranging portfolio of components and subject matter experts experienced in fluid and thermal management. A previous blog article from the Parker Aerospace Gas Turbine Fuel Systems Division’s thermal management team details the criteria for selecting a thermal management system supplier.
     

    “Because SWAP is such a key challenge with an airborne end use, thermal management needs to be a common design feature of every component and sub-system in electric or hybrid-electric aircraft.”

    Michael Humphrey, business development manager for thermal management solutions, Gas Turbine Fuel Systems Division of Parker Aerospace


    Challenges that can be met by an experienced thermal management systems provider

    It should be noted that heat density and precise location that needs to be the primary focus when assessing an entire thermal management system. Frequently, heat “spreading” – or a reduction in thermal density – is the first stage of creating a solution. Many materials and control components are capable of operating efficiently at extreme temperatures. Thus, reducing thermal density may allow a passive solution, such as heat dissipating into a large thermal mass, to be employed. Other TMS challenges include:

    • Multiple point sources of heat throughout the platform, each with heat densities or heat loads that vary over the operating cycle – Solutions range from copper/diamond composites that rapidly spread heat from a point source to large, complex cold plates utilizing single-phase and two-phase coolants for heat collection that is then transferred to a liquid- or vapor-to-air heat exchanger
    • Pathways through which heat moves require highly reliable connection points – Repair and maintenance demands frequently require high-pressure fluid connections capable of quick release without leakage. 
    • Out-of-the-ordinary location of heat sources – Safe and efficient rejection of heat may involve the unconventional utilization of structural elements of the platform. For example, Macrolaminate™ heat exchangers can facilitate transport of heated fluid or vapor close to an exterior surface that is adjacent to cold air. 

    Thermal management has widespread impact across these vehicles, integral with other technologies such as:

    • Universal low-cost motor controllers for electric propulsion, cooling, braking, flight control
    • Tailored motor solutions leveraging Parker global vehicle motor (GVM) technology 
    • Hydraulic power packs specialized for UAM requirements
    • Electric braking and mobility 
    • Power management via our integrated power management system (IPMS) technology  
    • Electrical mechanical actuation (EMA)  
    • Cockpit controls 

    The Parker advantage: proven system-level TMS capability

    The thermal management team at the Parker Aerospace Gas Turbine Fuel Systems Division offers proven thermal management system-level experience developing solutions for demanding environments, including applications for advanced defense and intelligence gathering systems employing technologies that create exceptional thermal density challenges.
     

    “With the DNA of an engineering-focused problem-solving culture, Parker’s TMS team offers the ability to optimize system performance with SWaP-focused solutions while maintaining aircraft safety, applying Parker’s full understanding of the needs of the regulatory authorities. Contributing further to this is Parker’s corporation-wide strength in the areas of materials – including composites – and the availability of subject matter experts to address any aspect of engineering at the component and sub-assembly level.”

    — Michael Humphrey, business development manager for thermal management solutions
     

    eVTOL aircraft require comprehensive system-level thermal management - Cold Plate - Parker Aerospace As the development, testing, and certification of eVTOL platforms accelerates, so too will the demands placed on the thermal management systems needed for these exciting vehicles.
