Abstract:
An apparatus for restraining and releasing a missile, comprising:a pair of circular restraining protrusions formed at a rear end portion of a missile nozzle portion;a missile side restraining and releasing means having:an operation cylinder engaged to a rear end surface of the restraining protrusion of the missile;an operation piston reciprocating within the operation cylinder; anda rigid sphere protruded from an outer surface of the operation cylinder when the operation piston is moved back and inserted into the outer surface of the operation cylinder when the operation piston is moved forwardly;a canister(launch tube) side restraining and releasing means having:a missile restraining portion fixed to the inner surface of the rear end portion of the canister into which the missile is inserted, with the circular restraining protrusion being inserted into the missile restraining portion;a fixing cylinder fixing portion into which the rigid sphere protruded from the outer surface of the operation cylinder is inserted; anda piston guide portion for guiding the rear end portion of the operation piston; anda combustion gas guide means for guiding a part of a combustion gas generated when launching the missile toward the rear end portion of the operation piston for thereby moving the operation piston forwardly, so that the rigid sphere is escaped from the rigid sphere restraining groove for thereby releasing the restrained state of the missile.
