Abstract

The invention discloses a compressor and a stator adjusting mechanism used for the compressor. The stator adjusting mechanism used for the compressor includes: an actuator, the actuator has a piston rod; wherein, the stator adjusting mechanism also includes: a linkage ring, the piston rod is connected to the linkage ring; a plurality of rocker arms, each One end of the rocker arm is connected with the stator vane of the compressor stator, and the other end is connected with the linkage ring, and can move on the linkage ring along the circumference of the linkage ring. The action of the piston rod causes the linkage ring to move in the axial direction of the compressor, and the linkage ring does not rotate in its circumferential direction. The stator adjusting mechanism of the invention has a simple structure, helps to improve the design precision, and can coordinate the movement of the rocker arm and the linkage ring.

Description

technical field [0001] The invention relates to a compressor and a stator adjusting mechanism for the compressor. Background technique [0002] At present, most aero engines use gas turbine engines. A gas turbine engine is mainly composed of an inlet, a compressor, a combustion chamber, a turbine, and an exhaust nozzle. The compressor pressurizes the air from the intake port into high-pressure air to be mixed with fuel in the combustion chamber to form high-pressure gas. [0003] A compressor usually consists of a rotor and a stator. The rotor rotates at a high speed to do work on the air flow from the intake port, thereby increasing the pressure and temperature of the air. The stator is the non-rotating part of the compressor, and its function is to guide Air flows in the axial direction of the compressor. Usually, a set of rotors and a set of stators are arranged alternately to form the first stage of the compressor. The compressor can consist of one or more stages. ...
