Delayed expansion mechanism for folding rudder sheets of small missile

Abstract

The invention discloses a delayed expansion mechanism for folding rudder sheets of a small missile, and belongs to the field of missile attitude controlling. Each delayed expansion unit which is composed of a first adapter plate, a second adapter plate and a rudder sheet lock pushing rod is arranged corresponding to each rudder sheet, and the rudder sheets are stably locked in a rudder cabin segment by the delayed expansion units to ensure that the rudder sheets are still in a locking state after the small missile is launched; and in the process of the flight of the small missile, the lockingof the rudder sheets can be released and the expansion of the rudder sheets can be completed quickly by driving the rudder sheet lock pushing rods to move at any time so as to realize the locking anddelayed expansion of the rudder sheets. According to the delayed expansion mechanism, the structure is simple, the controlling is easy, the response is quick, the reliability is high, the working requirements of the folding rudder sheets can be fully met, the stable locking of the rudder sheets can be ensured, and the delayed expansion of the rudder sheets can be realized effectively, so that theflexibility and accuracy of the rudder sheet controlling are effectively improved, then the flight accuracy and controlling flexibility of the small missile are ensured, and good application and popularization value is achieved.

Description

technical field [0001] The invention belongs to the field of attitude control of missiles, and in particular relates to a time-delay deployment mechanism for folding rudder blades of small missiles. Background technique [0002] With the continuous development of missile technology and the continuous improvement of the demand for modern war equipment, higher requirements are put forward for the functions of small missiles with local lethality. [0003] According to different application environments and application requirements, the shape and function of small missiles are also different. Among them, small missiles with folding rudders are more widely used. Usually, the main unfolding part of folding rudders is energy storage in advance. The torsion spring of the small missile; before the launch of the small missile, the folding rudder is accommodated in the cabin of the small missile, and the rudder is restrained by the inner wall of the missile launch tube; when the missil...

Problems solved by technology

However, according to long-term research and application, it has been shown that the influence of the rudder blades is different in each stage of the flight process of small missiles. However, the existing folding rudder structure cannot fully meet the above requirements and has certain limitations
