Problems solved by technology

[0003] Traditionally, servo mechanisms are used for rudder locking and angle control, but due to the increasingly complex flight profiles of launch vehicles, the requirements for servo locking and operating torque range are greater, and the torsional vibration system formed by rudders, transmission systems, and servos may also face aerodynamic pressure. problems caused by resonance

Abstract

The invention discloses a double-hinge-rod type air rudder locking, unlocking and buffeting restraining mechanism which comprises a mounting base, a left shaft system, a pin puller assembly, a connecting rod, a rudder locking shaft system and a right shaft system. Wherein one end of the left shaft system, one end of the pin puller assembly, one end of the rudder locking shaft system and one end of the right shaft system are all arranged on the mounting base; the other end of the left shaft system is connected with one end of the connecting rod, and the other end of the connecting rod penetrates through the other end of the rudder locking shaft system and is connected with the other end of the right shaft system; and the other end of the pin puller assembly is connected with the left shaft system. During flight, the rudder can be locked, the impact response can be reduced, and when unlocking is needed during flight and on the ground, the unlocking purpose can be achieved through actuation and manual operation.

Description

technical field [0001] The invention belongs to the technical field of launch vehicle separation mechanisms, and in particular relates to a double-hinged rod type air rudder locking, unlocking and buffeting suppression mechanism. Background technique [0002] Launch vehicles usually use rudder and wing-like structures to enhance flight stability, usually located at the tail of the sub-stage. With the continuous development of launch vehicle technology, functional requirements such as recoverability, drop zone control, and high-altitude launch have been put forward, which has put forward more practical requirements for the structure of rudder-like mechanisms that undertake attitude control, such as folding, unfolding, hanging and locking, etc. . [0003] Traditionally, servo mechanisms are used for the locking and angle control of the rudder. However, due to the increasingly complex flight profile of the launch vehicle, the servo locking and operating torque range are requir...
