What type of fuel tank safety system is the nitrogen generation system?

Asked by: John Buford

Aviation nitrogen generation systems (NGS) are the equipment used to generate pure nitrogen or nitrogen-rich air which helps to reduce the flammability of the void above jet fuel in aircraft fuel tanks.

What is nitrogen generation system?

Nitrogen generators or nitrogen generation systems are machines that can separate nitrogen molecules from compressed air. These nitrogen gas generators are capable of purities of up to 99.999% at flow are required for your scientific equipment.

What is fuel tank inerting system?

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.

What are the basic types of fuel tanks?

Aircraft typically use three types of fuel tanks: integral, rigid removable, and bladder.

What are the two types of fuel systems on an aircraft?

Various aircraft fuel components are necessary for loading and delivering fuel to the propulsion system. However, discussing the aircraft fuel system components, they unite to provide two fuel systems. That is the gravity feed system and fuel pump system.

What is nitrogen inerting?

Inerting, also known as inertization, is a process that uses inert nitrogen gas to limit the amount of oxygen from forming an otherwise volatile mixture. An application is designed to use the inerting process to eliminate the oxygen content and keep the interted area explosion-proof.

How does inerting system work?

Our inerting systems reduce the volatility of the ullage, or air volume above the fuel, in the aircraft fuel tank. 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.

What is the difference between purging and inerting?

Inerting differs from purging. Purging, by definition, ensures that an ignitable mixture never forms. Inerting makes an ignitable mixture safe by introduction of an inert gas.

What does Obiggs stand for?

Onboard Oxygen Gas Generation System. (OBIGGS/OBOGS) Study.

What is the purpose of Obiggs?

The OBIGGS is a system composed of well-proven equipment generating directly Nitrogen on board to fully protect the aircraft tanks against explosion. Autonomous, it does not require any logistics.

What is the background of SFAR 88?

SFAR 88 mandated a review of fuel tank system service history to reveal ignition sources in airplane fuel tanks due to unforeseen failure modes or factors not considered at the time of original certification of the airplane.

What is Cdccl in aviation?

Definition: Critical Design Configuration Control Limitations (CDCCL): As applied to Fuel Tank safety policy, this term refers to a feature of the fuel system design the integrity of which must be maintained to ensure that unsafe conditions do not develop.

Which gas is used for purging an aircraft fuel tank?

Which gas is used for purging an aircraft fuel tank? carbon dioxide. Why is the main fuel strainer located at the lowest point in the fuel system? it traps any small amount of water that may be present in the fuel system.

What are the fuel system components?

The fuel system is made up of the fuel tank, pump, filter and injectors or carburetor, and is responsible for delivering fuel to the engine as needed. Each component must perform flawlessly to achieve expected vehicle performance and reliability.

What is the purpose of the crossfeed system?

C- provides a means to maintain a balanced fuel load condition. 11 (8708) – What is the primary purpose of the crossfeed system? A- To allow the feeding of any engine from any tank.

What is a gravity feed fuel system?

Gravity feed aircraft fuel systems

This is the simplest of fuel systems commonly found in high wing aircraft with a fuel tank in each wing. A gravity feed system is designed with the fuel tanks above the engine and propulsion system, with lines feeding the fuel from the tank to the engine via gravity.

What are the two types of fuel systems?

The basic types of fuel injection systems are single-point fuel injection, multi-point fuel injection, sequential fuel injection, and direct injection.

What is the difference between gravity feed and fuel pump system?

The pump feed system is opposite to a gravity feed system in that the pump is able to provide sufficient pressure to not only move fuel to an engine that is higher than the tank, but to do so with the pressure required for a fuel-injection system.
