ABSTRACT:
A liquid propellant cannon includes an axially movable pump piston 25 which is exposed to propellant in a propellant chamber. The pump piston has a stroke that is shorter than the total length of the propellant chamber. For some or all of the rest of its length the propellant chamber 22 is divided by webs into parallel chamber portions. The pump piston causes uniform ignition of the liquid propellant charge during its relatively short stroke, while the chamber portions permit a substantially variation-free, compact reaction of the liquid propellant. The result is a relatively compact structure which provides uniform combustion behavior.
