Closure release device

Abstract

The invention discloses a closure release device, whcih comprises a closure folding mechanism, a closure initial locking mechanism and a closure unfolding-in-place locking mechanism, wherein the closure folding mechanism comprises a left driving plate, a left driven plate, a right driving plate, a right driven plate, an upper guide rail and a lower guide rail; the closure initial locking mechanism comprises an explosive bolt and a base; the closure unfolding-in-place locking mechanism comprises a rotating shaft, a torsional spring and push pins; the torsional spring, the left driving plate, and the right driving plate are fixed on the base via the rotating shaft; one end of the torsional spring is fixed on the base, and the other end of the torsional spring is fixed on the left driving plate or the right driving plate so as act as a driving force for enbaling the left driving plate or the right driving plate to rotate around the rotating shaft; and both the left driving plate and the right driving plate are movably connected with the base via the push pins. Accoridng to the closure release device, the applied principle is simple, practicability is strong, the function of blocking a jet nozzle of an engine can be met, jettisoning is not needed, safety influences on a carrier aircraft are eliminated, repeated use cna be achieved, the development cycle is shortened, and the development cost is reduced.

Description

technical field [0001] The invention relates to a blocking cap releasing device. Background technique [0002] During the empty platform test of the missile, in order to test the performance of the engine, a disposable throwable plug is generally used to block the engine tail nozzle. According to the characteristics of the aerodynamic environment and safety requirements of the loading point of the carrier aircraft, it is necessary to select a suitable cap structure and throwing method, and to simulate the trajectory of the cap throwing to ensure the safety of the cap throwing. However, in the actual flight process, the qigong environment of the carrier aircraft's mount point is complex, and the simulation process of the cap throwing trajectory cannot fully consider unpredictable factors, and it is impossible to predict the potential danger of the cap throwing state to the carrier aircraft. [0003] Therefore, it is necessary to provide a new technical solution to solve the ...
