Abstract

The invention discloses a fuel control system and a control method, and belongs to the technical field of turbine engines. The fuel control system comprises an open-loop pipeline and a closed-loop pipeline. According to the system, a full-authority digital control unit selects open-loop control or closed-loop control to supply fuel to an engine by controlling a working state of a fuel regulating pump, an on-off state of a servo valve and an on-off state of a shut-down electromagnetic valve, and the fuel control system has the advantages of being small in size, flexible to control, adjustable at any time and high in practicability. According to the control method of the fuel control system, a control command can be received according to a current working state of an aircraft, the fuel control system is controlled to execute corresponding operation according to the control command, a working state of the engine is detected according to the current working state of the aircraft, ignitionoperation is controlled to be executed if the engine flames out in air, control is convenient, and the emergency property is high.

Description

technical field [0001] The invention relates to the technical field of turbine engines, in particular to a fuel control system and a control method. Background technique [0002] In order to ensure the normal operation of the aircraft and the engine, it is necessary to use the fuel system to supply and adjust the fuel required by the engine under various working conditions and states, so as to ensure the safe and reliable operation of the engine and give full play to its performance. However, the fuel system currently used in aircraft uses a fuel regulation pump or a servo valve to supply fuel to the engine, which has the problem of large volume and inconvenient control. Contents of the invention [0003] In view of the above problems, a fuel control system and control method aiming at small volume and easy control are provided. [0004] The present invention provides a kind of fuel control system, is applied in aircraft, comprises: [0005] The fuel oil supply pipeline,...
