Description

Technical Field

[0001] This invention relates to the field of aircraft launch technology, and more specifically, to a quick-connect tooling and method for the protective cover of a densely packed launch box. Background Technology

[0002] Normally, the end cover of the launch container is protected by a protective cover to prevent it from being bumped or accidentally struck. The protective cover is usually installed on the cover using hinges and buckles, which requires no additional tools and is simple and quick to operate, but requires sufficient operating space. In combat readiness, the protective cover is removed, exposing the cover. When the aircraft is launched, the cover is broken through by the aircraft or by internal pressure, completing the launch and separation of the aircraft from the container.

[0003] To improve the integration level of weapon systems, the launch boxes need to be densely assembled, with small gaps between adjacent launch boxes. When the protective cover is installed and removed, conventional hinge and snap-on connections cannot be used. Instead, screw connections are mostly used, requiring special tools for installation and removal, which is complicated and inefficient. Summary of the Invention
