A rapid fire gun round is made with a composite chamber. The chamber is led by rotational motion rather than by reciprocating motion. The round will work in a recoilless gun configuration. An alternate arrangement permits multiple barrels to be arranged with an ammunition chain to form a Gatling gun configuration. A liner can be inserted in the gun barrel to be replaced with wear as appropriate.

Composite round/rapid fire gun

A liquid propellant gun having a chamber adapted to receive a projectile liquid propellant and having a breech area containing a fuel injection system and a valve internally thereof and a bolt which is chambered within said valve and adapted to move from a projectile load to a fire position. The movement of the bolt from projectile load to fire position is done in one movement and this is possible in that the valve is able to hold high-pressure, making unnecessary a forward jogging of the bolt before firing.

Liquid propellant gun, breech pressure axial injection

An injection system for a liquid propellant gun including coaxial flow vas giving complete mixing of two propellant components by convergent streams, wherein ullage is eliminated by closely contouring the valves with the gun chamber and the flow valves are automatically controlled by action of the propellant pump.
