Problems solved by technology

Among them, the electromechanical front cover uses a motor to drive a special mechanism to realize the opening of the cover before launch. Its structure is more complicated and the launch preparation time is longer; the integral detachment front cover uses gas shock waves, projectile impact force or explosive cables as power. In the initial stage of ignition of the booster engine, the overall falling off of the cover usually requires a relatively large impact force or explosive force, which has high requirements on the impact resistance of the projectile, and the flight distance when the cover falls off is limited, which is harmful to the projectile and the launch. The safety of the device has a certain impact; the fragile front cover also uses the gas shock wave or projectile impact force as the power to realize the opening and falling of the cover, and breaks into multiple pieces to reduce the impact on launch safety. The cover needs to prefabricate the broken groove and ensure its strength during storage and transportation, which is difficult to realize in the process

Abstract

The invention discloses a low-impact overall ejection type launching canister front cover and belongs to the technical field of rocket and missile launching. The low-impact overall ejection type launching canister front cover comprises a movable impact part, an energy storage spring, fixing fulcrum bars, pull bars, fixing locking rings, locking tongue pieces, a front cover body and a fixed support. The fixed support is fixed to the center of the front cover body. A hollow pipe of the movable impact part and a guide bar of the fixed support are in hole and shaft fit. The outer surface of the hollow pipe of the movable impact part and the outer surface of the guide bar of the fixed support are sleeved with the energy storage spring. One end of each fixing fulcrum bar is fixed to a flat plate of the movable impact part. One end of each pull bar is movably connected to the other end of the corresponding fixing fulcrum bar. Each locking tongue piece is movably connected to the other end of the corresponding pull bar. The fixing locking rings are fixed to flanges of a launching canister body. The front cover body is installed at the open end of the launching canister body through the cooperation of the locking tongue pieces and the fixing locking rings. The launching canister front cover can be effectively sealed and reliably opened and safely disengage.

Description

technical field [0001] The invention belongs to the technical field of launching rockets and missiles, and in particular relates to a low-impact integral ejection type launch box front cover. Background technique [0002] The front cover of the rocket and missile launch box is an important part of the rocket and missile launch box. During the storage and transportation process, the front cover ensures the effective sealing of the launch box and provides a suitable storage and transportation environment for rockets and missiles; during the launch process, the front cover needs to be reliably opened and safely dropped to ensure the safe launch of the projectile. The design of the front cover of the launch box has always been an important content in the design of rocket and missile launching devices. The key points include: 1) reducing the action time of the front cover opening and improving the launch efficiency; 2) reducing the impact of the front cover opening on the missile...
