Modular liquid propellant gun

摘要: A gun of the kind in which liquid propellant is burned firing chamber to fire a projectile from constructed so that number modules can be combined modular gun. Each module cam controlled, and common used control each The flexible having belt configuration permit arranged both circular groupings non-circular groupings, such as side by side. includes fixed, non-rotating eliminate need for tangential velocity correction factors accelerate mass barrel assembly operational speed. individual injection mechanism injecting at high pressure when non-hypergolic bi-propellant propellant. One or more hydraulic actuators are develop pressures operate other components gun, bolt. also engaged with interlock controls through cam. source pressurized fluid independent power weight profile kept minimum. system compound spool valve operates dual mode normal cyclic operation during maintain an open bolt condition armed but non-firing operations. misfire detection shutdown locks misfired closed without depressurize circuits include additional bypass circuits. two pistons yoked together operated single actuator inject into metered amounts constant mix ratio. valves pistons, drawn fuel on retraction strokes pistons. retracted away after burst isolate heat chamber. rotary lock mounted closely adjacent engages relieved area locked position quite small force will hold against combustion tending
