How many fuel boost pumps are in the Airbus A320 fuel system?
The system has six main fuel pumps. Two electrical transfer valves are mounted in each wing to permit fuel transfer from outer to inner tank. A cross feed valve controlled by a double motor allows both engines to be fed from one side or one engine to be fed from both sides.
Why does the aircraft’s fuel system have a boost pump?
Boost pumps provide a positive flow of fuel under pressure to the engine for starting and serve as an emergency backup in the event an engine-driven pump should fail. They are also used to transfer fuel from one tank to another and to pump fuel overboard when it is being dumped.
Which fuel is used in A320?
The family pioneered the use of digital fly-by-wire and side-stick flight controls in airliners. Variants offer maximum take-off weights from 68 to 93.5 t (150,000 to 206,000 lb), to cover a 5,740–6,940 km (3,100–3,750 nmi) range. The 31.4 m (103 ft) long A318 typically accommodates 107 to 132 passengers.
How much fuel does an Airbus A320 use?
Over 1,000 Kilometers, an Airbus A320–200 burns 3,090 kg of Jet fuel or about 3,987 L (liters) of fuel (with either CFM56–5B or V2500 engines). However, the Airbus A320neo burns only 2,790 kg per 1000 km, which is about 3,600 Liters of fuel.
How many fuel tanks does the A320 have?
Working of the Airbus A320 fuel system The wing tanks are further divided into inner and outer wing tanks summing to a total of five fuel tanks in an A320 aircraft. Each fuel tank is incorporated with a fuel pump connected through fuel lines and valves extending up to the two engines.
What are the APU main components?
Each auxiliary power unit consists of a fuel tank, a fuel feed system, a system controller, an exhaust duct, lube oil cooling system, and fuel/lube oil vents and drains.
What is APU supply?
The auxiliary power unit (APU) is a small gas turbine engine mounted in the tail cone of an aircraft to provide autonomous electrical and mechanical power for the following: Starting power for the main engines. Pneumatic power for cabin air conditioning systems. Shaft power for other pneumatic and hydraulic systems.
What is fuel boost pump?
An aircraft fuel boost pump, also known as an auxiliary electric pump, is responsible for delivering fuel to the aircraft engine before the engine starts. The aircraft fuel boost pump can also be used to supply fuel to the airplane engine if the engine driven or primary fuel pump fails.
How many pumps are provided in a fuel system Why?
They draw the fuel from the tank(s) and deliver it to the carburetor. The two pumps provide redundancy. The engine-driven fuel pump acts as the primary pump. The electric pump can supply fuel should the other fail.
What engine does the Airbus A320 use?
CFM56-5B
Powering the Airbus A320 family The CFM56-5B is the engine of choice for the A320 family, having been selected to power nearly 60 percent of the aircraft ordered. Today, it is the only engine that can power every model of the A320 family with one bill of materials.
What is the fuel used in Airbus?
Jet fuel (Jet A-1 type aviation fuel, also called JP-1A) is used globally in the turbine engines (jet engines, turboprops) in civil aviation. This is a carefully refined, light petroleum. The fuel type is kerosene. Jet A-1 has a flash point higher than 38°C and a freezing point of -47°C.
Where is the APU fuel pump located?
According to the image below it seems that the APU fuel pump at the aft side of the center fuel tank. And this is the view from inside the center fuel tank looking aft: Note the pump still draws fuel from the left line, and not the center tank, it activates automatically if the left side engine fuel pumps don’t provide the required pressure.
What is the difference between APU fuel pump and crossfeed?
APU FUEL FEED – An APU fuel pump is provided to start the APU when the main tank pumps are off or normal AC power is unavailable CROSSFEED – All tanks share a common crossfeed manifold. The crossfeed valve is normally closed unless crossfeed is required.
What happens if the Apu does not start during refueling?
An APU start is not permitted during a refuel/defuel procedure if the APU has failed to start or an b. A normal APU shutdown must be completed if a fuel spill has occured during the refuel defuel procedure. supply) during automatic refueling may stop the process.
Where is the fuel pump on the APS3200 accessory gearbox?
If you are looking for the high pressure fuel pump mounted on the APS3200 accessory gearbox, you can not find a dedicated fuel pump mounting pad in the gearbox. The fuel pump is integral to the fuel control unit and they are mounted piggyback to and driven by the oil pump which is the one that has a mounting pad in the gearbox.
