Abstract:

This patent application discloses submarine torpedo tube axial weapon restrainer for preventing a weapon from moving breechward in a torpedo tube once the weapon has been released for firing. An axial restrainer block is mounted within a housing on a wall of a torpedo tube. The block has a guide slot that extends into the torpedo tube for engaging a guide stud of a weapon to be loaded into the tube. The housing is provided with cam slots that allow the block to move axially along the torpedo tube. The cam slots permit the blocks guide slot to receive, engage or release the weapon guide stud in one of a load, lock or fire position, respectively. A hydraulic control system having three power cylinders controls the movement of the block. A first power cylinder mechanically connected to the block moves the block. Second and third power cylinders are used to control the amount of movement of the first power cylinder toward the breechward andor muzzleward end of the torpedo tube. In the critical firing situation, the second power cylinder ensures that the first power cylinder is only permitted to move towards the muzzleward end of the torpedo tube.
