Abstract : The present invention relates to projectile launching devices and more particularly to an energy storage and low-noise launch system using an elastomeric bladder as the energy storage medium. It is a general purpose and object of the present invention to provide an improved, impulse energy storage and transfer system. Further objects are that this system exhibit a relatively high mechanical efficiency, be simple, reliable and low in cost. These objects are accomplished with the present invention by providing, in combination, a device for storing potential energy in the form of a distended, fluid medium filled, elastomeric bladder and rapidly converting that stored energy into kinetic energy of the working fluid for quietly ejecting a projectile along with the stored fluid from the device and into the surrounding fluid medium. The stored working fluid flows through a tubular launch tube enclosing a projectile. The moving fluid acts to expel the projectile entrained therein. Such an energy storage and transfer system is particularly well suited for, but not limited to, submarine launcher system applications. The present invention can provide the energy required to quietly launch a projectile, such as a torpedo from a submarine. Keywords: Patents. (AW)
