Engine inlet gas uniform distribution acquisition device

Technical Field

The utility model relates to an engine inlet gas uniform distribution acquisition device, and belongs to the field of aviation machinery control.

Background

Because the flight envelope of the aircraft is wide, the working environment of the aircraft engine is greatly changed, and the engine needs to stably work under different air pressure and air temperature conditions. In recent years, with the development of aero-engine technology, aero-engines adopting electronic control and monitoring technology gradually replace traditional mechanically controlled aero-engines. It is often necessary to collect pressure and temperature data of the engine inlet gas for the ECU to control the engine.

At present, the method for collecting the temperature and the pressure of the inlet gas of the engine at home is to arrange probes on the inner wall of the inlet of the engine, and the probes are connected with a sensor conduit. The method can only collect one point on the circumference of the engine inlet during collection, the collected parameters are not representative, and the error is large.
