More Information
Summary:The invention discloses a deformable noise-reduction thrust vector nozzle. The deformable noise-reduction thrust vector nozzle is composed of a front end steering piece, a circular rotating D-shaped transition piece and a rear end steering piece. The circular rotating D-shaped transition piece is fixedly connected with the front end steering piece and the rear end steering piece. The front end steering piece is located on the front portion of the circular rotating D-shaped transition piece, and the rear end steering piece is located on the rear portion of the circular rotating D-shaped transition piece. The vector nozzle is mounted at a turbine outlet of an engine, and by controlling the circular rotating D-shaped transition piece to rotate, the front end steering piece rotates at any angle of 360 degrees. Rotating shaft holes in the outlet are matched with the rotating shaft for controlling a connecting piece to move and connect two parts of structures. Airflow is backwards exhaustedby a converging section o
