    • The invention relates to a shooting system comprising a housing and parts that can be moved relative thereto, i.e. a tube, a tube closure, and a silencer, as well as a non-self-locking threaded spindle which has a left-handed threaded section in one of the halves thereof while having a right-handed threaded section in the other half. The silencer and the tube closure are mechanically coupled to one respective threaded spindle section by means of one respective nut such that a translational movement of the silencer is converted into a rotational movement of the spindle and the movement of the spindle is converted into a translational movement of the tube closure, in such a way that both parts perform translational movements in opposite directions because of the right-handedness and left-handedness of the spindle. The tube is disposed to also be movable relative to the housing and can be coupled to the tube closure in such a way that the tube is entrained by the tube closure at least during a translational movement of the tube closure, during which the tube closure moves away from the silencer from a shot-triggering position.

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