    A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance.

  6. Active tip-clearance control - Wikipedia

    en.wikipedia.org/wiki/Active_tip-clearance_control

    Active clearance control (ACC) is a method used in large aircraft gas turbines to improve fuel efficiency during cruise. This is achieved by setting the turbine tip clearance at more than one operating point and contrasts with passive clearance control which sets it for only one condition and is explained below.

  7. Turbine inlet air cooling - Wikipedia

    en.wikipedia.org/wiki/Turbine_Inlet_Air_Cooling

    An inlet air cooling system installed in a desert-dry area to increase turbine power output. Turbine inlet air cooling is a group of technologies and techniques consisting of cooling down the intake air of the gas turbine. The direct consequence of cooling the turbine inlet air is power output augmentation.

  8. Bleed air - Wikipedia

    en.wikipedia.org/wiki/Bleed_air

    Bleed air in aerospace engineering is compressed air taken from the compressor stage of a gas turbine, upstream of its fuel-burning sections.Automatic air supply and cabin pressure controller (ASCPC) valves bleed air from low or high stage engine compressor sections; low stage air is used during high power setting operation, and high stage air is used during descent and other low power setting ...

  9. Combined cycle power plant - Wikipedia

    en.wikipedia.org/wiki/Combined_cycle_power_plant

    Systems burning low quality fuels such as brown coal or peat might use relatively expensive closed-cycle helium turbines as the topping cycle to avoid even more expensive fuel processing and gasification that would be needed by a conventional gas turbine. A typical single-shaft system has one gas turbine, one steam turbine, one generator and ...
