Abstract

The invention discloses a thrust vectoring nozzle and a control method thereof. A plurality of telescopic arm mechanisms with the same structure are arranged in the circumferential direction to form an annular nozzle arm, the telescopic arm mechanisms can stretch out and draw back in the axial direction of an annular base, so that an outlet of the nozzle is in different step shapes, the flowing direction of gas at the outlet of the nozzle is controlled, and then the thrust direction is changed, and a vector propulsion function is realized. Therefore, the jet flow direction of the tail of an aero-engine can be controlled in a 360-degree all-around mode under the condition that the nozzle does not deflect, complex motion control requirements such as torsion do not exist, the equipment structure is simplified, the control mode is simple, the problem of complex control needed for controlling the airflow direction by rotating the nozzle is solved, and the spray angle of the nozzle can be quickly, efficiently and reliably changed.

Description

technical field [0001] The invention belongs to the field of vector engines, and more specifically relates to a vector nozzle and a control method thereof. Background technique [0002] In order to cope with the increasingly complex maneuverability control requirements of new types of aircraft in the air in the future, it is an inevitable trend to equip aero-engines with thrust vectoring functions, and the technology of vectoring thrust nozzles is the key core of aero-engines that realize thrust vectoring functions One of the techniques. [0003] The vector propulsion engines that have been verified by actual flight rely on complex and fine mechanical structures to control the deflection of the engine tail nozzle to generate vector propulsion power. At present, the vector thrust nozzle technology is gradually developing towards the trend of simplifying the control structure and reducing the weight. For example, Chinese patents CN201410253892.6, CN201910425150.X, CN20141073...
