Telescoping Pressure Balanced Gas Generators Launchers for Underwater Use
Abstract
A launching apparatus including a launch tube having a fore end and an aft end, each end having an opening formed therein. A muzzle cap is fit to the fore end of the launch tube and a breech mounting is formed at the aft end of the launch tube. A primary plenum housing is seated in the aft end of the launch tube, the primary housing having a fore end and an aft end. A first telescoping cylinder is initially positioned within the fore end of the primary housing and a second telescoping cylinder is initially positioned within the aft end of the primary housing. A first telescoping piston is formed in the first telescoping cylinder and a second telescoping piston formed in the second telescoping cylinder. A ram plate is connected to the first telescoping piston and the second telescoping piston is connected to the breech mounting. A gas generator is provided within said primary housing and a projectile is seated between the ram plate and the muzzle cap. The first and second telescoping cylinders and the first and second telescoping pistons expand in multiple stages of extension from the main housing and propel the projectile.
