The engine-driven fuel pump must be capable of delivering the maximum needed flow at appropriate pressure to obtain satisfactory nozzle spray and accurate fuel regulation. These engine driven fuel pumps may be divided into two distinct system categories:

Some older reciprocating engine aircraft have been equipped with hand-operated fuel pumps. They are used to back up the engine-driven pump and to transfer fuel from tank to tank. The wobble pumps, as they are known, are double-acting pumps that deliver fuel with each stroke of the pump handle.

Oct 23, 2024 · Once passed through the exchanger and the filter, the fuel is pumped by the high-pressure pump to the fuel nozzles in the combustion chamber. The fuel is also used to run the actuators of systems such as the variable stator vanes …

An APU engine uses the aircraft fuel system to supply fuel to the fuel control. An electric boost pump may be used to supply fuel under pressure to the control. The fuel usually passes through an aircraft shutoff valve that is tied to the fire detecting/extinguishing system.

An aircraft fuel system allows the crew to pump, manage, and deliver aviation fuel to the propulsion system and auxiliary power unit (APU) of an aircraft. Fuel systems differ greatly due to different performance of the aircraft in which they are installed.

Jul 2, 2024 · The fuel pump, often a high-performance electric pump, is vital in delivering the correct amount of fuel to the engine at the required pressure. Each aircraft fuel pump system component is meticulously designed to uphold the highest …

Our successful origins in auxiliary power units (APUs) gear pumps and hydraulic and actuation systems expand pump technology to engine fuel pump systems. This advancement in design comes from extensive experience in developing similar systems for the Joint Strike Fighter.

Our mechanical pumps are designed to maintain fuel flow to aircraft engines at highly precise rates and pressures. Reduce technical and program risks on your road to engine certification with Eaton’s main engine fuel pumps.

Eaton’s main engine fuel pumps are installed on 70% of the commercial jet engines currently fl ying today. They are utilized on military, commercial, regional and business aircraft engines worldwide. This series of gear fuel pumps contain a centrifugal boost stage, fuel fi …

Jet fuel pumps play a critical role in the safe and eficient operation of commercial aviation. The performance and reliability of these pumps directly impact aircraft operation, fuel consumption, and overall flight safety.
