Embodiment
[0029] A new type of axisymmetric converging nozzle is mainly composed of a cylinder body 1, a drive adjustment mechanism, a sealing member, a central blocking member and an external rectifying member. Specifically:
[0030] The front end of the cylinder body 1 is connected with the engine as a supporting member for the entire nozzle.
[0031] The driving adjustment mechanism is mainly composed of an actuator 2, a synchronous adjustment ring 3, a pull rod 4 and a convergence adjustment piece 5. Wherein, the actuator cylinder 2 is arranged along the circumference of the nozzle, the front end is connected to the outer wall of the cylinder body 1 through a mechanical connection, and the rear end is connected to the synchronous adjustment ring 3; the rear end of the synchronous adjustment ring 3 is connected to the pull rod 4 through a rotating pair; The tie rod 4 is evenly distributed along the nozzle pipe circumference, and the other end is connected to the outer middle section...
