Definitions
- the invention relates to a method for creating the necessary pressure and fuel consumption in the fuel system of an aviation gas turbine engine (hereinafter referred to as GTE).
- GTE aviation gas turbine engine
- the closest to the claimed invention is the method of operation of the fuel system of the auxiliary power unit of the CCD, containing a fuel pump with an electric drive, a fuel pump with a mechanical drive from the drive box, a fuel metering / distributor, a controller, sensors, which consist in supply of fuel to the combustion chamber (hereinafter referred to as CS) of the CCD at revolutions of the CCD of 1-8% due to the activation and operation of the fuel pump with an electric drive when the speed of rotation of the fuel pump with a mechanical drive is insufficient to ensure the required fuel consumption when the speed of the CCD is reached 8% of the controller shut off the fuel pump with an electric drive, supplying fuel to the CS due to the operation of a mechanically driven fuel pump (US Patent X ° 9206775, IPC B64D37 / 34, F02C7 / 236, F02M31 / 16, F02M37 / 00, publ. 08.12 .2015).
- a disadvantage of the known fuel system of the auxiliary power unit of the CCD is that with the effective use of similar approaches to the design for a cruising aircraft engine, other combinations of operating modes of two fuel pumps with adjustable (electrically driven fuel pump) and unregulated performance are required ).
- the technical problem to which the invention is directed is to effectively use the advantages of two fuel pumps with different types of drives on the main aviation GTE, minimize their disadvantages and obtain high specific and optimal parameters of fuel pumps, excluding restrictions on fuel consumption and pressure in rotation frequency the high-pressure compressor at the stage of ignition of the CS when the GTE is started up, in reducing the amount of heating of the fuel from the fuel pump with unregulated capacity (mechanical esky motor) basic modes for low fuel consumption (in zone modes: a small gas flight small gas cruising flight), in improving the engine resiliency of functional failure
- 25 reduced pressure or turn off the earth gas mode and all engine modes with rotor speeds of the gas turbine engine and the drive shaft of a mechanically driven fuel pump more than ground earth mode provide the mechanically operated fuel pump for supplying the required fuel consumption to the camera combustion of the gas turbine engine and the creation of the necessary flow and fuel pressure for the operation of hydraulic actuators, in addition, on the operating modes of the gas turbine engine with the rotor speeds of the gas turbine engine are above 40% and the occurrence of conditions with insufficient fuel pressure at the inlet or outlet of the fuel pump with mechanically driven, as well as when the fuel inlet temperature to the mechanically driven pump is below + 10 ° C, turn on and / or increase the rotor speed for the electrically driven fuel pump and maintain the pressure or temperature of the fuel at the required level.
- the fuel system and gas turbine engine with fuel supply from an electrically driven pump up to 40% of the maximum rotor speed of the gas turbine engine, gradually reduce the rotational speed of the electrically driven fuel pump, and / or open the bypass of the fuel from the electrically driven pump output at the entrance to the fuel system, at rotor speeds of a gas turbine engine of more than 40%, provide the necessary fuel consumption by feeding from the fuel pump from the fur
- the required pressure and fuel consumption for the operation of hydraulic actuators and fuel distribution units after the gas turbine launch has been completed, are additionally driven from the electrically driven fuel pump during the operation stages of the electrically driven fuel pump in the fuel system.
- FIG. 1 shows a diagram of a method for creating the necessary pressure and fuel consumption in a fuel-supply system for gas turbine engines.
- an electrically driven pump 1 is used as the main pump at the initial stage of GTE start-up (not shown), providing fuel supply processes to the CS (not shown) and supplying the working fluid (fuel) for the hydraulic actuators to start the engine.
- Earth gas mode and all engine modes with higher rotational frequencies of GTE rotors and drive shaft of a mechanically driven fuel pump 2 are fully supported by the operation of a mechanically driven fuel pump 2 for supplying the required flow of fuel to the engine CS and creating the required working fluid pressure for operation hydraulic actuators.
- the fuel pump with an electric drive 1 can be turned off, or work in a closed loop with a reduced flow, or be connected to the fuel supply to the CS, or to maintain required parameters of pressure and fuel temperature in special conditions.
- the controller 4 controls the connection and operating modes of the fuel pump with electric drive 1 and fuel metering / distributor 3.
- Fuel metering / distributor 3 provides for fuel metering in CS and fuel distribution through the fuel system.
- the implementation of the present invention with the above features eliminates restrictions on fuel consumption and pressure on rotational speed when starting a gas turbine engine, reducing the amount of fuel preheating from a fuel pump with unregulated performance of a mechanically driven fuel pump in basic modes with low fuel consumption, increase engine failure by functional failure
