Abstract: A motor drive controller is provided that includes a current source inverter. The current source inverter includes driver circuitry configured to generate switching commands; a variable current source configured to generate a variable current that regulates power in a motor; and motor commutation circuitry configured to receive the variable current and switching commands, and to commutate phase currents that are output to the motor.

Abstract: Ammunition containers incorporate an advanced sealing/latching arrangement as well as a lightning mitigation scheme that exhibits a number of advantageous features. A cover assembly is provided that separates the latching functionality from the sealing functionality such that the latching assembly is rotatably engaged and the cover seal is provided via radial (rather than axial) compression of an annular sealing component. In addition, a novel lightning mitigation system also functions as a convenient method of grasping and transporting the containers.

Abstract: A machine gun assembly includes, but is not limited to, a receiver, a barrel extension, and an interlock element. The barrel extension is mounted to the receiver and moves between forward and retracted positions with respect to the receiver. The barrel extension is configured for quick-release engagement with a barrel. The interlock element is mounted to the receiver and moves between a blocking position and a clear position. The interlock element has a blocking portion positioned to obstruct movement of the barrel extension to the forward position while in the blocking position and the blocking portion is positioned to permit movement of the barrel extension to the forward position while in the clear position. The interlock element moves to the blocking position when the barrel disengages from the barrel extension and moves to the clear position when the barrel is correctly engaged with the barrel extension.

Abstract: A payload mount adapter assembly for use with an aircraft is disclosed. The payload mount adapter assembly includes, but is not limited to an upper section that is configured for mounting to the aircraft and a lower section that is configured to receive a payload. The lower section is releasably engaged with the upper section such that the lower section is substantially unadjustable with respect to the upper section when the lower section is in a fixed state and the lower section is substantially adjustable with respect to the upper section when the lower section is in a released state.

Abstract: A weapon system is provided. The weapon system includes a receiver and an operating group. The operating group includes a barrel extension at least partially housed within the receiver and arranged to axially translate relative to the receiver; an operating rod (op-rod) assembly arranged to axially translate within the barrel extension; and a bolt assembly arranged to axially translate within the barrel extension. The system further includes a gas accelerator coupled to the barrel and the op-rod assembly; a buffer assembly including a self-centering spring and a hydraulic piston assembly having a first end coupled to the receiver and a second end coupled to the barrel extension; and a feeder coupled to the receiver and configured to provide the round to the operating group.

Abstract: A loading machine includes a drum cam configured to rotate and having a cam path. A first track is positioned proximate the drum cam. A rammer subassembly is engaged with the drum cam and the first track. The rammer subassembly is configured to move between an extended position and a retracted position as the drum cam rotates. The rammer subassembly has a first rammer section engaged with the cam path and configured to move longitudinally during rotation of the drum cam. The first rammer section includes a first gear engaged with the first track such that longitudinal movement of the first rammer section causes rotation of the first gear. A second rammer section is telescopically coupled with the first rammer section and is engaged with the first gear such that rotation of the first gear causes the second rammer section to telescopically move with respect to the first rammer section.

Abstract: A gun sight is disclosed herein for use with a weapon configured for superelevation. The gun sight includes, but is not limited to, an imaging system configured to capture an image of an area down range of the imaging system, to display the image on a display unit having a display, and further configured to rotate in elevation. The gun sight further includes, but is not limited to, a drive mechanism configured to rotate the imaging system. The gun sight still further includes, but is not limited to, a processor communicatively coupled with the drive mechanism and with the imaging system, the processor configured to receive information from the imaging system relating to the image and to control the drive mechanism based on the information to rotate the imaging system in a manner that causes the image to remain on the display when the weapon is superelevated.

Abstract: A weapon system includes a receiver and an operating group with a barrel extension arranged to axially translate relative to the receiver. In the firing condition, the op-rod assembly and bolt assembly are driven by the drive spring such that the round is guided into the chamber and the op-rod assembly and bolt assembly are locked to the barrel extension and a forward momentum of the op-rod assembly is imparted to the operating group and the round is fired. A portion of an impulse stops the forward momentum of the operating group. In the recoil condition, the operating group is driven rearward by the remaining portion of the impulse, the gas accelerator imparts additional rearward momentum to the op-rod assembly and bolt assembly and stops rearward momentum of the barrel and barrel extension, and the op-rod assembly and the bolt assembly are stopped by the drive spring.

Abstract: A capacitive reactive armor assembly for shielding a vehicle is disclosed herein. The capacitive reactive armor includes, but is not limited to, a first flyer plate, a second flyer plate, and a capacitor positioned between the first flyer plate and the second flyer plate. The capacitor is configured to store an electric charge and to explosively short circuit when the capacitor is penetrated while the capacitor is electrically charged. The explosive release of energy from the capacitor pushes the first and second flyer plates apart interfering with the penetration of a shaped charge jet or ballistic penetrator.
