F-35 Lightning II Fuel and Inerting System Powered by Parker Aerospace - Fighter Jets - Parker AerospaceAs the United States military embarked to build the second ever fifth-generation fighter aircraft, Parker Aerospace’s Fluid Systems Division (FSD) was selected in the mid-1990s to provide the fuel system and the onboard inert gas generating system (OBIGGS) for the F-35 Lightning II program. The scope and complexity of this program posed a significant challenge to the FSD engineering team, and required the breadth of knowledge and capabilities of the team to successfully deliver a qualified fuel and fuel tank inerting system. 

Parker was responsible for the system architecture, system analysis, design, development, and qualification of all the components within the fuel and fuel tank inerting systems. FSD was uniquely qualified to provide the fuel and inerting system for this aircraft due to our long history of providing fuel system components in military applications and our ability to furnish all of the necessary components within the F-35 fuel and fuel tank inerting systems. These systems utilize over 130 unique components with a total part count approaching 270 per aircraft.

 

Fuel tank inerting on the F-35

For the F-35 program, there were additional challenges to design the fuel and inert gas generation system for three different aircraft variants for specific branches of the military. Each variant had different performance requirements which drove different fuel and inerting system architectures. Parker was able to utilize common hardware between all three aircraft variants even though the system architectures were unique.

Parker Aerospace’s Fluid Systems Division (FSD) has been ASM Palleta major supplier of aircraft fuel tank inerting systems and components since the 1960s. Fuel tank inerting systems create a non-combustible atmosphere in the air space or ullage gas present over the liquid fuel in an aircraft fuel tank. This non-combustible or inert atmosphere prevents a fire from occurring inside the fuel tank. The means by which that inert atmosphere is created has evolved considerably over the last 50 years and Parker has remained at the forefront of each technology advancement.

 

Nitrogen and Halon for military aircraft

Evolution of Fuel Tank Inerting for the Aerospace Industry - Galaxy c-5 airplane - Parker AerospaceFuel tank inerting systems were initially developed to help protect military aircraft from hazards unique to combat and supersonic aircraft. Parker’s first aircraft fuel tank inerting system was a cryogenic liquid nitrogen (LN2) system used on the supersonic XB-70 aircraft. The LN2 system extracts liquid nitrogen from cryogenic-storage dewars installed onboard the aircraft, vaporizes the liquid into gaseous nitrogen and sends it to the fuel tanks to provide an inert blanket over the top of the fuel. Several research programs conducted by the Air Force and the Federal Aviation Administration (FAA) subsequent to the XB-70 also used Parker LN2 inerting equipment. In the early 1970s, LN2 technology produced by Parker Aerospace was put into regular service on all C-5 aircraft. This system remains in service today.

Evolution of Fuel Tank Inerting for the Aerospace Industry - Halogen pressure and vent control valve - Parker Aerospace

The evolution of fuel tank inerting systems away from the complexities of cryogenic LN2 systems to Halon-based systems followed in the late 1970s. Halon inerting systems discharge a fire-suppressing agent into the fuel tanks to create an inert atmosphere over the fuel. Parker proliferated Halon inerting equipment on programs such as the F-16 and F-117A. Like the LN2 systems that came before them, Halon inerting systems require a fixed amount of inertant to be loaded and stored on the aircraft before each flight. The capacity of these stored gas systems is limited to the amount of inertant that is carried onboard the aircraft.

 

Hollow-fiber membrane air separation module advancements

Evolution of Fuel Tank Inerting for the Aerospace Industry - F22 Raptor Aircraft - Parker Aerospace In the 1980s and 1990s, advances in hollow-fiber membrane air separation technology enabled nitrogen to be generated onboard an aircraft from atmospheric air. Air separation modules (ASMs) contain thousands of these hollow-fiber membranes and are the heart of the contemporary fuel tank inerting system. High-pressure air enters the ASM and is separated into nitrogen-enriched and oxygen-enriched air streams. The nitrogen-enriched air stream is directed to the fuel tank to provide a blanket of inert gas over the top of the liquid fuel in the tank.

The development of the ASM for aircraft use enabled a new class of inerting system that does not require inertant to be stored and carried onboard the aircraft. Inerting systems using Parker-supplied ASM technology were explored on several advanced aircraft programs and culminated in the widespread use of Parker ASMs on the F-22.

 

Evolution of Fuel Tank Inerting for the Aerospace Industry - Air Separation Module Fuel tank inerting comes to commercial aircraft

For many years, fuel tank inerting systems remained exclusively within the realm of military aircraft and were perceived to be unnecessary and impractical for use on commercial airliners. However, the loss of TWA 800 in 1996 forced a re-examination of the fuel tank safety paradigm for commercial transport aircraft. Between 1996 and 2001, an extraordinary body of work was performed by a consortium of industrial, academic and governmental researchers to determine viable means by which to improve fuel tank safety on commercial transport aircraft.  

Parker led the way in demonstrating how hollow fiber membrane-based ASM technology developed for military aircraft applications could be implemented in a practical and viable way on commercial transport aircraft. Parker also worked closely with FAA and provided inerting equipment and expertise in support of a flight test program using the FAA’s 747SP. Technology advances demonstrated in this time frame ultimately paved the way for new rulemaking for fuel tank safety which was implemented by the FAA in 2008.

 

Modern aircraft inerting

Since 2008, inerting systems and equipment provided by Parker FSD have been installed on almost every large commercial airliner in domestic service today. In fact, Parker’s aircraft inerting systems and equipment are in operation on well over 10,000 aircraft worldwide. Parker FSD maintains its leadership position through a close working relationship with its sister division in the Parker Filtration Group, which manufactures the ASM used on many Parker inerting applications. 

 

Parker continues to explore new ways of improving the performance as well as reducing the weight, cost and bleed air consumption of the existing ASM-based technology. At the same time, Parker is developing future inerting technologies that will be more ideally suited for helicopters, UAVs, and business jets.

Aircraft Lightning Protection Rises to New Heights - Aircraft-Lightning-Strike - Parker AerospaceAircraft lightning strikes occur more frequently than you might think. It’s estimated that on average, commercial aircraft lightning strikes occur every 1,000 hours of flight time or approximately once per year.

When a strike happens, lightning attaches itself to an extremity, such as the nose, leading edge of the wing, or wing-tip, travels along the exterior of the airplane, exits at another aircraft extremity, and continues on to hit the ground.

Up to 1 million volts can be delivered in a single lightning strike. The damage inflicted to the aircraft can vary depending on the duration of the lightning strike, the amount of lightning energy dissipated by the aircraft, and the lightning attachment and exit locations on the aircraft.

  Lightning strike protection 

Today’s aircraft incorporate state-of-the-art composite materials, specialized computer systems, and components that are lighter in weight, and offer better reliability and longevity, but can also make them more susceptible to damage by lightning. These technological advances are prompting regular updates to strict lightning safety regulations, underscoring the priority placed on lightning protection equipment.

Aircraft manufacturers design and continually test their airplanes for lightning strike protection to keep passengers safe and protect sensitive equipment from damage.

A broad array of components and systems designed to withstand, direct, and dissipate the powerful discharge of a lightning strike are required for lightning protection. This equipment must be tested and verified by the manufacturers to meet the stringent lightning protection regulations. 

  Lightning protection testing
