Problems solved by technology

[0002] Due to the hollow structure of the traditional aero-engine binary nozzle, it cannot effectively shield the front-end hot-end components, resulting in very weak stealth capabilities
The conventional binary plug vector nozzle only adds a closed center body in the center of the nozzle. This kind of closed center body has a large cross-sectional area, which seriously affects the adjustment range of the throat area of ​​the nozzle, thereby affecting the work of the engine. point; in order to ensure the normal throat adjustment range of the aero-engine, it is necessary to increase the structural size of the nozzle, resulting in an increase in the weight of the nozzle

Abstract

A novel binary vector nozzle is characterized in that it includes a circular rotating square cylinder, an outer wall, a swirling leaf structure, a shielding plate, a vector adjusting plate, a side wall, a connecting rod, an actuator, and a sealing block; Among them: the front end of the circular rotating square cylinder is connected with the engine as the supporting member of the entire nozzle; the vector adjustment mechanism is composed of a vector adjustment plate, a connecting rod and an actuator; the actuator is arranged on the side wall, and the front end is mechanically connected. It is connected to the outer wall of the side wall, and the rear end is connected to the connecting rod through the rotating pair; the front end of the vector adjustment plate is connected to the cylindrical surface of the rear end of the shielding fixed plate in rotation, and the left and right ends are installed in the slideway of the side wall; The rod drives the vector adjusting plate to realize the vector deflection of the nozzle. The invention has the advantages of ensuring the adjustment range of the throat area of ​​the conventional binary nozzle, making up for the defects of the conventional binary plug-type vector nozzle, and simultaneously having the advantages of small size, simple structure and easy integration with the fuselage.

Description

Technical field [0001] The invention relates to the field of aero-engine nozzles, in particular to a new type of binary vector nozzle. Background technique [0002] Due to the hollow structure of the traditional binary nozzle of aero-engine, it cannot effectively shield the hot end components of the front end, resulting in weak stealth capability. Conventional binary plug vector nozzles only add a closed center body in the center of the nozzle. This closed center body has a large cross-sectional area, which seriously affects the adjustment range of the nozzle throat area and affects the operation of the engine. Point: In order to ensure the normal throat adjustment range, the aeroengine needs to increase the structural size of the nozzle, which causes the weight of the nozzle to increase. Therefore, in order to make up for the shortcomings of the traditional binary nozzle and the conventional binary plug vector nozzle, a new type of binary vector nozzle needs to be designed. Su...
