Description
technical field [0001] The invention relates to the field of aviation testing, in particular to an aviation fuel adjustment testing system. Background technique [0002] The fuel regulation system is an important part of the aircraft engine control system. With the improvement of aero-engine control accuracy requirements, the performance of the fuel regulation system is particularly important. In addition, the performance failures that are often encountered in practice, such as over-temperature, over-rotation, speed swing, etc., are often caused by regulator failures. Therefore, the research on the detection of aero-engine fuel control system has very important engineering significance. In view of the intricate characteristics of the working mechanism of the aero-engine fuel control system, it is impossible to realize the detection and diagnosis of corresponding faults without a thorough understanding and study of the engine. [0003] The aviation fuel adjustment test sys...
