Abstract

The invention discloses a cover blocking release device. The blocking cover releasing device comprises a blocking cover folding mechanism, a blocking cover initial locking mechanism and a blocking cover unfolding position locking mechanism. The blocking cover folding mechanism includes a left driving sheet, a left driven sheet Sheet, right driving sheet, right driven sheet, upper guide rail and lower guide rail; the initial locking mechanism of the plug cover includes an explosive bolt and a base; the locking mechanism of the plug cover unfolded in place includes a rotating shaft, a torsion spring and a push pin. The spring, the left driving blade and the right driving blade are fixed on the base by the rotating shaft, one end of the torsion spring is fixed on the base, and the other end of the torsion spring is fixed on the left driving blade or the right driving blade, as the left driving blade or the right driving blade The driving force of the blade rotating around the rotating shaft, the left driving blade and the right driving blade are movably connected with the base through the push-pull. The plug release device is simple in principle and strong in practicability, and satisfies the function of plugging the tail nozzle of the engine. It also eliminates the safety impact on the carrier because it does not need to be thrown away, and can be reused, shortening the development cycle and reducing the cost of development cost.

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 ...
