Abstract

The disclosure provides a nozzle assembly of a vector aeroengine, which includes a spray barrel, and a direction adjuster is arranged at one end of the spray barrel, and the direction adjuster adjusts the direction of the airflow ejected from the spray barrel, so that the aircraft can obtain excellent maneuverability. The direction adjuster includes a cylindrical part and a square part, the cylindrical part is rotatably connected to the spray barrel, and the driving mechanism drives the direction adjuster to rotate to realize full-angle adjustment of the airflow direction. The square part includes guide plates, two guide plates are arranged oppositely, and the driving assembly drives the guide plates to move. Compared with the prior art, this solution uses the driving mechanism to drive the direction adjuster to rotate, combined with the movement of the guide plate, it can conveniently realize the full-angle adjustment of the airflow direction. Compared with the prior art, the structure of the nozzle assembly is greatly simplified and the nozzle size is reduced The manufacturing cost of the assembly is low, and the spout assembly is easy to maintain.

Description

technical field [0001] The present disclosure relates to a vectoring aircraft engine nozzle assembly. Background technique [0002] With the rapid development of aviation technology, the performance of aero-engines is getting better and better, and the application of high-thrust vectoring engines is becoming more and more extensive. [0003] Using the vector engine can make the aircraft obtain good maneuverability, and the maneuverability of the aircraft will make the aircraft have more excellent survivability in complex environments. [0004] The vectoring engine in the prior art generally utilizes the swing ability of the tail injection assembly to achieve corresponding engine performance. However, the tail injection assembly in the prior art has a complex structure and is very difficult to maintain, which restricts the application environment of the vector aeroengine. Contents of the invention [0005] The disclosure provides a vector aeroengine nozzle assembly, which...
