Sawtoothed angle regulation mechanism for two-dimensional spray pipe

Abstract

The invention relates to a sawtoothed angle regulation mechanism for a two-dimensional spray pipe. The sawtoothed angle regulation mechanism comprises a mounting base, an actuator cylinder, a pull rod, a right sealing plate, a right baffle plate, a mounting base, a pull rod, a mounting seat, a left baffle plate and a left sealing plate, and is specifically characterized in that the mounting base is fixedly arranged on a two-dimensional spray pipe constriction regulation plate; a side sealing baffle plate is fixedly arranged on the left and right mounting edges of a round-to-square cylinder; one end of the actuator cylinder is connected with the mounting base, the other end of the actuator cylinder is connected with the hinged position of the pull rods through a rotating pair; the right baffle plate and the left baffle plate are connected at a tip end position through a rotating pair, and the rotating pair is kept being perpendicular to the constriction regulation plate; the outer end surfaces of the right sealing plate, the right baffle plate, the left baffle plate and the left sealing plate are guaranteed to be in the same one plane; the right sealing plate and the left sealing plate slide in the right baffle plate and the left baffle plate through sliding pairs, so that the effective regulation on the sawtoothed angle of the two-dimensional spray pipe can be realized. The sawtoothed angle regulation mechanism has the advantages of being simple in structure, fewer in movement connecting parts, good in stealth performance, and capable of realizing the regulation on the sawtoothed angle of a two-dimensional spray pipe outlet.

Description

technical field [0001] The invention relates to the field of aeroengine nozzle design, in particular to a binary nozzle sawtooth angle adjustment mechanism. Background technique [0002] The sawtooth angle of the outlet modification of the traditional binary nozzle and axisymmetric nozzle cannot be adjusted. Under different engine working conditions, the sawtooth angle of the outlet modification has a great influence on the stealth performance of the nozzle. According to different nozzle throat areas and vector deflection conditions, in order to obtain the nozzle sawtooth angle with the best stealth performance, it is necessary to design a sawtooth angle adjustment mechanism with a simple structure, less moving parts, good stealth performance, and more. Contents of the invention [0003] The purpose of the present invention is to provide a binary nozzle adjustable sawtooth control mechanism, which can effectively adjust the sawtooth angle of the nozzle under different nozz...
