ABSTRACT:
This invention provides an annular piston, annular control valve, liquid propellant gun system, having a dual angle injection mechanism to provide both bore and chamber gas requirements with a single injection control valve. The dual angle feature assures a stable combustion zone. A flexible lip on the projectile is used in conjunction with the dual angle injection mechanism to positively eliminate backflow of propellant through the injection mechanism during the ignition phase of the gun cycle.
