Abstract

The invention discloses a deflation valve, a compressor deflation control system and an aeroengine having the deflation valve. The deflation valve of the present invention uses the gas in the gas collection chamber of the compressor as the control medium, cancels the eight oil pressure control pipelines of the original deflation structure, and is beneficial to the miniaturization design of the engine. There will be interference with other parts of the aircraft, which is easy to install and use, and the valve can be opened or closed by controlling the power on and off of the electromagnet assembly through the electronic controller, which realizes the electronic control function and makes the air discharge of the compressor more flexible, which can be well Fully meet the electronic control requirements of the engine.

Description

technical field [0001] The present invention relates to the technical field of compressor deflation, in particular to a deflation valve, and also to a compressor deflation control system using the above deflation valve, and in particular to a compressor deflation control system using the above compressor Air bleed control system for aeroengines. Background technique [0002] Aeroengines are mainly composed of compressors, combustion chambers, turbines and other components. At a certain speed, when the air flow decreases to a certain value, the compressor may experience surge. Compressor surge is an unstable working state of the engine, which causes vibration of the blades and the entire engine, and may cause damage to the compressor and the engine. Therefore, when the engine is working, surge is not allowed. Practice has proved that for a multi-stage axial flow compressor with a boost ratio of less than 10, releasing air from the middle stage of the compressor is a simple ...
