Abstract

A machine gun comprising a gun housing; a rotor assembly positioned within the gun housing; a barrel cluster including a plurality of barrels extending forward from the rotor assembly; one or more vents providing a path for expulsion away from the rotor assembly of gases emanating from a cartridge chambered in one of the plurality of barrels; and one or more of a rotor lock mechanism, a feed mechanism, a delinking and transfer mechanism, a searing mechanism, a drive system, a self-contained hardware barrel clamp, a threaded adapter barrel clamp, integrated mounts, and/or multiple feed inlet locations.

Claims (42)

1. A machine gun comprising:

a gun housing;

a rotor assembly positioned within the gun housing;

a barrel cluster including a plurality of barrels extending forward from the rotor assembly;

one or more vents providing a path for expulsion away from the rotor assembly of gases emanating from a cartridge chambered in one of the plurality of barrels;

a motor configured to rotate the rotor assembly,

a motor housing, and

a rotor lock mechanism configured to lock the rotor assembly directly to the motor housing, preventing rotation of the barrel cluster.

2. A machine gun comprising:

a gun housing;

a rotor assembly positioned within the gun housing;

a barrel cluster including a plurality of barrels extending forward from the rotor assembly;

one or more vents providing a path for expulsion away from the rotor assembly of gases emanating from a cartridge chambered in one of the plurality of barrels;

a feed mechanism with a feeder sprocket that is concentric to and rotates in an opposite direction of the barrel cluster so as to cause an inertial load of the feed mechanism to counteract an inertial load of the barrel cluster.

3. The machine gun of claim 2 , further including a motor configured to rotate the rotor assembly, a bonded clutch solenoid, an external control interface, and a gun control module including a processor and one or more software modules that are configured to, when executed by the processor, respond to external control signals to disengage the bonded clutch solenoid, stopping rounds from being fed into the rotor assembly, the gun control module further configured to control the motor to run any remaining rounds through the firing cycle and spin the barrel cluster multiple times to ensure chambers are clear, and electrically safe the machine gun.

4. The machine gun of claim 2 , further including a searing mechanism having a longitudinally movable bolt searing ramp.

5. The machine gun of claim 2 , further including a drive system having a feedback control loop with a brushless DC servo motor, a position encoder sensor, and a programmable drive, allowing variable rate of fire, and current and temperature sensing.

6. The machine gun of claim 2 , wherein the motor is configured to rotate the rotor assembly and a motor housing with cooling features, transferring excess heat to ambient environment.

7. The machine gun of claim 2 , wherein the plurality of barrels include respective non-threaded barrel end portions and further including a threaded adapter barrel clamp with threads to mount a multitude of muzzle devices to the non-threaded barrel end portions.

8. The machine gun of claim 2 , further including one or more stabilizer adapters.

9. The machine gun of claim 8 , wherein the one or more stabilizer adapters include integrated mounts for suspension lugs.

10. The machine gun of claim 8 , wherein the one or more stabilizer adapters include load transferring pads.

11. A machine gun comprising:

a gun housing;

a rotor assembly positioned within the gun housing;

a barrel cluster including a plurality of barrels extending forward from the rotor assembly;

one or more vents providing a path for expulsion away from the rotor assembly of gases emanating from a cartridge chambered in one of the plurality of barrels;

a delinking and transfer mechanism including a non-rotating reciprocating delinking shuttle and a rotating barrel cam operably associated with the non-rotating reciprocating delinking shuttle to control linear movement of the non-rotating reciprocating delinking shuttle to delink and transfer each round.

12. A machine gun comprising:

a gun housing;

a rotor assembly positioned within the gun housing;

a barrel cluster including a plurality of barrels extending forward from the rotor assembly;

one or more vents providing a path for expulsion away from the rotor assembly of gases emanating from a cartridge chambered in one of the plurality of barrels;

a self-contained hardware barrel clamp configured to prevent each barrel of the plurality of barrels from rotating about an axis thereof,

wherein the barrel clamp includes a lock housing with a slot, a lock plunger, and a spring-loaded rotating barrel lock whereby the barrel clamp is removable from the barrel cluster by inserting a tool into the slot of the lock housing, applying a force to the lock plunger, rotating the spring-loaded rotating barrel lock, and sliding the barrel clamp off the barrel cluster.

13. A machine gun comprising:

a gun housing;

a rotor assembly positioned within the gun housing;

a barrel cluster including a plurality of barrels extending forward from the rotor assembly;

one or more vents providing a path for expulsion away from the rotor assembly of gases emanating from a cartridge chambered in one of the plurality of barrels;

further including a feed mechanism with a feed mechanism housing configured to allow for a single feed inlet location of multiple possible feed inlet locations.

14. The machine gun of claim 13 , wherein the feed mechanism includes a feed chute inlet, a feeder door adapter, and one or more feeder closeouts, the feed mechanism housing includes a bottom, sides, and a top, and the feed mechanism housing is configured to allow for the feed chute inlet at one of the bottom, the sides, and the top at a time.
