  2. Thrust-specific fuel consumption - Wikipedia

    en.wikipedia.org/wiki/Thrust-specific_fuel...

    For example, Concorde cruised at 1354 mph, or 7.15 million feet per hour, with its engines giving an SFC of 1.195 lb/(lbf·h) (see below); this means the engines transferred 5.98 million foot pounds per pound of fuel (17.9 MJ/kg), equivalent to an SFC of 0.50 lb/(lbf·h) for a subsonic aircraft flying at 570 mph, which would be better than even ...

  3. Aircraft engine controls - Wikipedia

    en.wikipedia.org/wiki/Aircraft_engine_controls

    Fuel primer pump - A manual pump to add a small amount of fuel at the cylinder intakes to assist in starting a cold engine. Fuel-injected engines do not have this control. For fuel-injected engines, a fuel boost pump is used to prime the engine prior to start. Fuel quantity gauge - Indicates the amount of fuel remaining in the identified tank ...

  4. Aircraft engine performance - Wikipedia

    en.wikipedia.org/wiki/Aircraft_engine_performance

    Aircraft engine performance refers to factors including thrust or shaft power for fuel consumed, weight, cost, outside dimensions and life. It includes meeting regulated environmental limits which apply to emissions of noise and chemical pollutants, and regulated safety aspects which require a design that can safely tolerate environmental hazards such as birds, rain, hail and icing conditions.

  5. Aircraft fuel system - Wikipedia

    en.wikipedia.org/wiki/Aircraft_fuel_system

    A single-engine piston aircraft has a simple fuel system; a tanker (such as the KC-135), in addition to managing its own fuel, can also provide fuel to other aircraft. [1] Fuel is piped through fuel lines to a fuel control valve (usually known as the fuel selector). This valve serves several functions. The first function is to act as a fuel ...

  6. K-factor (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/K-factor_(aeronautics)

    For aircraft fuel flow meters, K-factor refers to the number of pulses expected for every one volumetric unit of fluid passing through a given flow meter, and is usually encountered when dealing with pulse signals. [1]

  7. Fuel control unit - Wikipedia

    en.wikipedia.org/wiki/Fuel_control_unit

    For an aircraft engine, changes in airspeed or altitude cause changes in air speed and density through the engine, which would then have to be manually adjusted for by the pilot. A fuel control unit attempts to solve those problems by acting as an intermediary between the operator's controls and the fuel valve.

  8. Aviation fuel - Wikipedia

    en.wikipedia.org/wiki/Aviation_fuel

    Piston-engined aircraft use leaded gasoline and those with diesel engines may use jet fuel (kerosene). [1] By 2012, all aircraft operated by the U.S. Air Force had been certified to use a 50–50 blend of kerosene and synthetic fuel derived from coal or natural gas as a way of stabilizing the cost of fuel.

  9. Aero Engine Controls - Wikipedia

    en.wikipedia.org/wiki/Aero_Engine_Controls

    Aero Engine Controls is the former name of Rolls-Royce Controls and Data Services.The company produces engine control software, electronic engine controls (EEC), fuel metering units (FMU), fuel pumps and engine actuators for a large number of common commercial and military aircraft. [1]
