Abstract
A firing assembly for a stored energy projectile launcher of the type hav an energy storage device that is pressurized by a fluid. The projectile is mechanically latched in its launch tube and the aft end of the projectile cooperates with the breach end of the launch tube to define a breach chamber that communicates with and is pressurized with the bladder. A valve in a line from the breach chamber is electrically controlled to move a piston and release the mechanical latch when fluid pressure is provided to the piston chamber. The pressure used to overcome the force needed to raise the piston is taken from the energy storage device. No addition of energy to the system is required, with the exception of a short electrical impulse signal, to open a full port valve acting instantaneously on the rear face of the projectile.
