Abstract
A Gatling type machine gun system whose rotational operation of subsystems is accomplished by way of a plurality of electronically controlled motors. The Gatling type gun system includes a core gun, a feeder subsystem, and a transfer subsystem each of which must operate at particular instance and speed to accomplish the proper operation of the gun system. Control of the gun and subsystems is provided by electronically controlled motors.
Claims20
A revolving battery machine gun, comprising:
- a core gun assembly including a barrel cluster having a plurality of radially disposed gun barrels rotationally carried by a gun rotor, a bolt assembly configured to chamber and extract an ammunition round into each of the plurality of radially disposed gun barrels, and a gun motor coupled for axial rotation of the gun rotor;
- a feeder assembly having a feed sprocket configured to individually draw a plurality of ammunition rounds from a source of ammunition, an extractor sprocket rotationally carried with the feed sprocket, and a feeder motor coupled for axial rotation of the feed sprocket and the extractor sprocket;
- a transfer assembly having a transfer sprocket configured to transfer each of the plurality of ammunition rounds between the feeder assembly and the bolt assembly, and a transfer motor coupled for axial rotation of the transfer sprocket;
- and
- an electronic controller that provides a discrete motion command signal to each of the gun motor, the feeder motor, and the transfer motor, wherein the discrete motion command signal has a trajectory profile corresponding to a desired rate of fire.

An electronic drive system for a revolving battery machine gun, comprising:
- an electronic gun motor coupled for axial rotation of a rotor of a gun barrel assembly;
- an electronic feeder motor coupled for axial rotation of a feed sprocket configured to draw a plurality of ammunition rounds from a source of ammunition;
- an electronic transfer motor coupled for axial rotation of a transfer sprocket configured to transfer each of the plurality of ammunition rounds between a feeder assembly and a breach assembly;
- and
- an electronic controller that provides a discrete motion command signal to each of the electronic gun motor, the electronic feeder motor, and the electronic transfer motor, wherein each said discrete motion command signal has a trajectory profile corresponding to a desired rate of fire.
2 more elements
An electronic transfer assembly for a revolving battery machine gun, comprising:
- a transfer sprocket rotatable to receive an ammunition round from an extractor sprocket of a feeder assembly to a bolt assembly of the revolving battery machine gun;
- an electronic transfer motor coupled to rotate the transfer sprocket;
- and
- a programmable micro controller programmed to send a motion command signal to the electronic transfer motor, the motion command signal having a transfer trajectory profile that alternates between a lower threshold value and an upper threshold value, wherein the lower threshold value corresponds to an ammunition round transition between the extractor sprocket and the transfer sprocket and the upper threshold value corresponds to an ammunition round transition between the transfer sprocket and the bolt assembly.
