Throat offset aerodynamic vectoring nozzle with vertical take-off and landing function and control method

Abstract

The invention discloses a throat offset type pneumatic thrust vectoring nozzle with the vertical lifting function. The throat offset type pneumatic thrust vectoring nozzle comprises a vertical lifting nozzle device body. An inner runner of the nozzle sequentially comprises a first throat front convergence section, a first throat, a second throat front expansion convergence section and a second throat. The body with the vertical lifting function is composed of a rotating shaft, a nozzle rear body capable of rotating around the rotating shaft and an accessory of the nozzle rear body. The nozzle rear body rotates to divide main flow into upper airflow and lower airflow, and the upper airflow and the lower airflow pass the inner surface of the nozzle rear body, flow through a vertical lifting channel and flow along the outer curved surface of the nozzle rear body; and air flows backwards horizontally and is vertically sprayed out downwards, airflow turning is finished, and vertical lifting is achieved. Meanwhile, under the situation that the nozzle rear body is not moved, the few rapid changes of resultant force and resultant force torque of an aircraft are achieved by controlling the flow, speed and direction of secondary flow injected at the first throat through the throat offset type pneumatic thrust vectoring nozzle, and the need for stable suspension of the aircraft in air in the vertical lifting process is met.

Description

technical field [0001] The invention relates to the field of aircrafts, in particular to aircrafts that simultaneously require a thrust vectoring propulsion system and a vertical take-off and landing. Background technique [0002] With the development of science and technology, more and more aircraft are equipped with thrust vectoring aeroengines. For future land-based and carrier-based vertical take-off and landing fighters, not only vertical take-off and landing technology is needed to help them take off and land in small spaces (such as cities, ship decks, etc.), but thrust vectoring technology is also needed to help them take off and land in small spaces (such as cities, ship decks, etc.). Better maneuverability in level flight to win air battles. Therefore, the nozzle device with thrust vectoring technology and vertical take-off and landing technology will have a good application prospect. [0003] Today, there are many designs for thrust vectoring nozzles and VTOLs, ...
