Problems solved by technology

However, this approach also has some risks
If two sets of identical sensor systems are configured, there are many types and quantities of sensors. If two sensors are installed at each position, the difficulty of setting will increase; and if the current sensor is abnormal due to external force, even if you switch to Another set of sensor systems for backup, another sensor at the same position is very likely to cause the same damage and abnormality, which will cause the two sets of sensor systems to be unusable

Abstract

The invention provides a control method of an aero-engine, which divides the sensing system into a main sensing module that affects the basic operation of the engine and an auxiliary sensing module that only plays an adjustment role; the main sensing module is set into two sets as the main / The backup module is switched, and the signal sensed by the auxiliary sensing module in the emergency state is directly ignored and the preset default value is used to ensure that the engine can run within the normal range to ensure that the aircraft is flying in a safe state. In terms of structure and assembly, the second set of auxiliary sensing modules is omitted, and the structure is simpler and easier to realize assembly; risk of damage resulting in unusability.

Description

technical field [0001] The invention relates to the field of aviation aircraft, in particular to a control method of a piston type aircraft engine. Background technique [0002] The engine controller is the control core of the engine management system. Its basic function is to collect sensor signals based on the engine speed and load. It is always in the best running state under working conditions and external working conditions. [0003] In the field of aviation, flight safety is the top priority, and aero-engines are the core of flight power, and the operating status of aero-engines is very important. In the prior art, in order to prevent abnormal operation of the control engine caused by the abnormality of the current sensor, two sets of the same sensing system are usually set up, and when the operating sensing system is abnormal, the control system switches to another sensing system. However, this approach also has some risks. If two sets of identical sensor systems a...
