| 摘要 |
The illustrative embodiment of the present invention is a launch system that includes a closure that, in use, is attached to one or both ends of a missile canister. The closure is blown off of the canister before there is any contact between it and the nose of the missile. The closure incorporates an actuation mechanism that releases the closure when there is a rapid increase in pressure within the canister, such as when the booster of a canistered missile fires. The actuation mechanism is not, however, responsive to the magnitude of the pressure within the canister. As a consequence, the closure will not release if there is a slow build-up of pressure within the missile canister.
