VERTICAL TAKE-OFF AND LANDING TYPE THROAT-SHIFTING AERODYNAMIC VECTORING NOZZLE BASED ON DEFLECTOR

A vertical take-off and landing type throat-shifting aerodynamic vectoring nozzle based on a deflector, comprising: a fixing part disposed on the lower wall surface of a front expansion and convergence section of a second throat (9), and a kitchen-knife-shaped deflector plate (6) located at the rear side of the fixing part and rotatable about a rotating shaft (8); under a flat flight mode, the head of the kitchen-knife-shaped deflector plate (6) and the inner wall surface of the fixing part are closely attached and sealed, and the inner surface and the upper side wall surface of the kitchen-knife-shaped deflector plate (6) form a circulating passage in the front of the second throat (9); under a vertical take-off and landing mode, the kitchen-knife-shaped deflector plate (6) rotates such that the tip head thereof is in contact with the upper wall surface of the front expansion and convergence section of the second throat (9). By means of rotation by no more than 90° of the kitchen-knife-shaped deflector plate
