摘要： 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.

摘要： A liquid propellant is burned in the bulk mode and in pulses to produce high combustion pressures with large power outputs. The pulsed high pressure liquid propellant combustion is also used for producing sound waves for underwater seismic exploration. The high combustion pressures produced by burning the liquid propellant in the bulk mode and in pulses may be used to overcome high back pressures such as those existing at deep drilling depths and in deep ocean depths.

摘要： An automatic weapons effects simulator (AWES) reproduces the visual and acoustic signatures associated with the firing of a weapon used in combat troop engagement simulation. The AWES is directly integrated into the weapon and allows the weapon operator to utilize the basic weapon mechanism in the same manner as with the original parts and at a cost advantage as compared to the cost of blank ammunition.

摘要： A liquid propellant modular gun has a slim profile and is constructed for wide latitude in gun cluster configuration.The modular gun has a stationary barrel and is externally driven and cam operated by a drive cam and a control cam.The drive cam has one internal spiral cam track for driving the bolt forward to a projectile firing position and another internal spiral cam track for driving the bolt rearward to a projectile loading position.The control cam is mounted for rotation at the forward end of the drive cam and controls the injection of liquid propellant into the combustion chamber and an electrical igniter.A water injection mechanism is also associated with the control cam for injecting a small amount of water into the combustion chamber after the firing of each round to cool the combustion chamber structure by internal water cooling. The water injection mechanism is also effective to purge propellant from the combustion chamber in the event of a misfire.The bolt is rotated to a locked position at the forward end of its travel where locking lugs on the bolt are engaged with mating lugs on the barrel so that all breach loads caused by chamber pressure are carried through the barrel rather than the receiver. This permits the receiver to be made quite light.

摘要： A liquid propellant modular gun has a main cam which is driven at a multiple of the gun firing rate and which has internal cam surfaces operatively associated with the bolt while the bolt is driven forward to load and fire and backward to accept another projectile.The gun incorporates a control cam driven at the gun firing rate and effective to unlock the bolt after firing of a projectile so that the bolt can be returned to its rearward position under the control of the main cam.The main cam acts to time all the remaining mechanisms of the gun to the bolt motion.The accelerating force for the bolt is provided by hydraulic pressure applied directly to the bolt area.Energy stored in the bolt from the force of the accelerating hydraulic pressure is converted into rotary energy and is stored in the main cam and other rotating devices geared to the main cam.The stored rotary energy in the main cam is used in combination with residual gas pressure remaining in the gun barrel for a part of the bolt return stroke to accelerate the bolt rearward.Energy losses, including those caused by hydraulic pressure drop, friction and windage, are made up by a pumping system receiving its energy from the gas pressure added to the gun as a part of the firing of each projectile.
