Abstract

The invention discloses a jet flow thrust vector device based on plasma flow control. The jet flow thrust vector device comprises a thrust vector spraying pipe and a plasma exciter; the thrust vector spraying pipe comprises an air intake way, an airflow transition section and an expansion section, and the thrust vector spraying pipe generates main jet flow and provides thrust; and the plasma exciter controls the main jet flow. By means of the jet flow thrust vector device, an external connection air source and a complex airflow pipe are not needed, and the response speed of the plasma exciter is higher.

Description

technical field [0001] The invention belongs to the field of aircraft engine thrust vector control, in particular to a jet thrust vector device based on plasma flow control. Background technique [0002] In the design of traditional aircraft power plants, it is considered that the engine can only provide forward thrust, and when the aircraft performs attitude control such as turning, climbing, diving, and rolling, it can only rely on the deflection of the aerodynamic rudder surface to generate asymmetric aerodynamic moments. . The emergence of thrust vectoring technology has changed this phenomenon. The thrust vectoring device has the ability to control the yaw, pitch, and roll of the aircraft. Agility and post-stall maneuvering flight are the development direction of future fighter jets. The thrust vectoring device can improve the maneuverability and agility of the aircraft, and even have the ability to maneuver under the post-stall state. At low speeds and high angles of...
