摘要： A small lightweight weapon system for integration into an unmanned aerial vehicle comprises a weapon operating group which utilizes blowback operation to fire a full-powered centerfire rifle ammunition. An operating rod of the weapon operating group has an axis of translation offset from the longitudinal axis of the barrel thereby creating a moment couple on the system. A motor assembly controls the operation of the weapon operating group. Through a gear train, actuation of the motor assembly lifts a sear against a return torsion spring, which holds the operating group back when not firing. The gear train comprises a one way flywheel disconnect to increase the torque of the direct current motor and overcome the force of the torsion spring. Intelligent motor commutation and burst control are achieved through an encoder and software package.

摘要： A drive for a weapon having a drive cam and a connecting rod unit guided in the drive cam. The drive cam includes the firing cycle of the weapon. A connecting rod unit has a front pin and a rear pin, a strut pin. With its front pin, the connecting rod unit engages in the drive cam. The front pin is also connected to a crank, which is driven by an external drive. The strut pin is connected to an overall control slider of a breech block of the weapon. An emergency stop device, which when a shot is fired makes a pin extend and ensures that the overall control slider is taken along. If, on the other hand, no shot is fired, the pin is not made to extend and the overall control slider not moved. Parts of the drive may in this case continue to run.

摘要： A drive for a weapon is provided, wherein rotational motion of a motor is converted to a forward or reverse motion of the breech in a simple manner using the Scotch yoke principle. In order to allow rest periods of the breech in the end positions, the crank radius is defined by a control cam, which changes when the crank is rotated. The hinge pin of the crank may be externally driven via a pinion shaft. A yoke pin is arranged in a groove of the crank so as to be radially displaceable and carries the breech carrier or the breech in a groove extending transversely to the direction of fire via a sliding block. Two rollers are arranged on the crank pin and run in control cams in the weapon or crank housing. The control cam is subdivided into different sectors/sections, thereby achieving the desired motion of the breech.

摘要： A drive, having a quick stop mechanism, for a breech is axially adjustable relative to a weapon barrel, and includes a motor, two counter-rotating chains and sprocket wheels that guide the chains. Engaging cams and control cams are integrated into the chains. A slide mounted at the bottom of the breech is displaceable transversely to the direction of fire and has a groove that the engaging cams engage to entrain the breech in a forward or reverse motion relative to the direction of fire. The engaging cam transporting the breech forwards is displaced from the groove while the control cam displaces the slide simultaneously to its center position via its ascent ramp, thereby allowing breech rest periods in the forward limit position. Firing causes the slide to move from the center position to the left hand side whereas it remains in the center position when no shot is fired.

摘要： A drive for a breech/breech carrier renders it axially adjustable relative to a weapon barrel. The drive includes a motor, two engaging cams mounted on a chain arranged below the breech and guided around two sprocket wheels. A slide is mounted in a guide at the bottom of the breech/breech carrier so as to move at a right angle to the direction of fire, with a groove extending over its entire width. The respective engaging cam entrains the breech in forward motion relative to the direction of fire, or in reverse motion, once the shot is fired, and transports the breech forwards, is displaced from the groove, and moves backwards without the breech, thereby allowing breech rest periods in a forward position. During firing, the slide moves, whereas it remains stationary when no shot is fired so no further engaging cam can entrain the breech backwards.
摘要翻译：用于后膛/后膛托架的驱动器使其相对于武器枪杆可轴向调节。驱动器包括一个电动机，两个连接凸轮安装在一个链条上，布置在后膛下方并引导绕两个链轮。滑动件安装在后膛/后膛托架底部的引导件中，以与火焰方向成直角移动，其凹槽在整个宽度上延伸。相应的接合凸轮相对于火焰方向夹带臀部向前运动，或者反向运动，一旦射击被射击，并将后膛向前运送，则从凹槽移出，并且在没有后膛的情况下向后运动，从而允许后膛休息期处于前进位置。在射击期间，滑块移动，而当没有射击时，它保持静止，因此没有进一步的接合凸轮可以将后膛向后夹带。

摘要： A reciprocally-cycled, externally-powered weapon may include a rotative driver connected via a crank and connecting rod to the operating group of the weapon. The connecting rod may be connected to a pinion that meshes with a translating rack and a stationary rack. The translating rack may be connected to the operating group, and the stationary rack may be fixed to the receiver of the weapon. The energy needed to fire the weapon may be supplied by an energy generator. The minimum amount of energy supplied by the energy generator may be independent of the speed of translation of the operating group and may be sufficient to reliably result in cartridge ignition, thereby providing an infinitely adjustable firing rate.

摘要： An automatic cannon for a monergole liquid propellant which is designed as a continuously firing drum-type weapon whereby the supply of projectiles, the loading and the dosaging process take place in parallel. The weapon housing of the automatic cannon includes a drum which has a plurality of drum chambers and is disposed in a drum housing so that the drum chambers can be successively rotated into a firing position aligned with the gun barrel. Each drum chamber accommodates a respective projectile chamber and a respective differential piston arrangement for the liquid propellant. The drum is driven in a hybrid manner by a longitudinally displaceable slide, which in turn is driven in one direction by the firing gases supplied through a gas conduction arrangement and in the other direction by a linear electric motor.

摘要： A rapid-stop device for the control roller of an automatic weapon wherein for a space-saving arrangement, a brake unit forming part of the rapid-stop device is disposed in a longitudinally axial bore of the control roller. Within its jacket, the brake unit includes brake shims and pretensioned spring elements 79. The brake unit jacket is mounted on a central mandrel, which is fixed to the cradle housing, so as not to be displaceable in the axial direction, and is connected with the control roller so that it can rotate with same and so that the control roller can move axially relative to the jacket. For a braking process required in the case of malfunction or during normal shut-down of the automatic weapon, a trigger catch lever or a rapid-stop catch lever disposed in the housing engages in the sole catch edge of a brake disc which is coaxial with the support mandrel. At the same time, a control disc, which is drivingly connected for rotation with the control roller and which is normally connected with the brake disc in a forming locking manner by an axial displacement arrangement, displaces the brake disc, under the inertia of further rotating parts connected to the control disk, in the direction of the brake shims, and thus performs a safe and attenuated brake stroke.
