What is fuel tank inerting?
Collins Aerospace’s fuel tank inerting systems improve aircraft safety by reducing oxygen in the fuel tank to prevent combustion, even if a spark is present. As fuel is consumed during flight, the fuel level in the tank is lowered and the remaining oxygen in the ullage is replaced by non-flammable inert gas.
How many fuel tanks did Concorde have?
17 fuel tanks
The Concorde had 17 fuel tanks that could hold a total of 31,569 gallons (119,500 liters) of kerosene fuel. The main tanks were located in each wing (five on each side) and fuselage (four). The Concorde also had three auxiliary or trim fuel tanks (two in front and one in the tail).
What is sfar88?
The acronym stands for Special Federal Aviation Regulation 88. By December 2004, operators must include Federal Aviation Administration (FAA)-approved provisions in their inspection and maintenance programs to assure the safety of their aircraft fuel systems. …
Does helicopter use oxygen as fuel?
Part of the oxygen contained in the fuel tank is replaced by Nitrogen, keeping the vapours non-flammable. Hence, compressed air is directly tapped on Helicopter engine air and transformed into NEA that can be directly distributed in the fuel tanks.
What kind of Technology is used for fuel tank inerting?
The primary focus of the fuel tank intering work was the characterization and application of Hollow Fiber Membrane (HFM) gas separation technology to generate nitrogen-enriched air (NEA) for commerical transport airplane fuel tank inerting.
How does on-board fuel tank inerting work?
On-board fuel tank inerting would involve ullage washing during some or all of an aircraft flight cycle with a system that generates NEA on the aircraft with engine bleed air or some other means.
How does The FTIs protect a fuel tank?
The FTIS provides protection against fuel tank fire and explosion by creating inert conditions within the ullage space of the fuel tanks. Pressure, oxygen, and temperature data acquired via analog sensors are used by the controller to support the distribution of nitrogen enriched air (NEA) into the fuel tank ullage.
What do you need to know about inert gas?
This required the development of an on-board inert gas generating system (OBIGGS) with the capability of providing a required amount of NEA throughout the ground/flight profile.
