Modularized stern room and rudder control transmission mechanism

Abstract

The invention discloses a modularized stern room and rudder control transmission mechanism. The stern room and rudder control transmission mechanism comprises a stern room shell, a steering engine mounting seat, a steering engine, an air rudder, a gas rudder, a connecting rod assembly and the like; the steering engine mounting seat is fixedly connected to the stern room shell, one end of the steering engine is hinged to the steering engine mounting seat through a pin shaft, and the steering engine can swing through the pin shaft; the other end is connected with the connecting rod assembly through a pin shaft; the output mode of the steering engine is a linear output mode; the air rudder is connected to the stern room shell through a shaft sleeve and a shaft end locking nut; the gas rudder is connected to the rear end frame of the stern room shell through a gas rudder support; the connecting rod assembly can convert linear motion of the steering engine into synchronous rotation of the air rudder and the gas rudder. The mechanism is simple and compact, all parts are tightly attached to the inner wall of the stern room shell and are located outside the maximum outer envelope line of an engine jet pipe, equipment inside the stern room is directly connected with the engine after being mounted and debugged, and modularized assembling of a rocket body is achieved.

Description

technical field [0001] The invention belongs to the technical field of carrier rockets and the like, and in particular relates to a modular tail compartment and a rudder control transmission mechanism. Background technique [0002] The tail cabin is the last cabin of the rocket structure. It is connected to the rear flange of the engine by bolts to enclose the engine nozzle and protect the engine nozzle from external mechanical damage during storage and transportation; it is not protected from external mechanical damage during flight. The impact of the external airflow prevents the nozzle from being blown by the airflow; the tail compartment is also used as an installation space for instruments and equipment, where the steering gear, gas rudder, air rudder, transmission system, power supply of the vector control system are installed, and the instruments of the control system and other systems are installed. equipment. [0003] Since the outlet diameter of the engine nozzle ...

AI Technical Summary

Problems solved by technology

[0003] Since the outlet diameter of the engine nozzle is larger than the throat diameter, if the instruments and equipment in the tail compartment are large, it is necessary to install the tail compartment shell on the engine first, and then install and debug the instruments and equipment in the tail compartment. It is difficult to install and debug the structural form of the instrument, which is not conducive to the modular assembly of the rocket body
