GUN POD ASSEMBLY

Umbilical Weapon Harnesses (Weapons Electrical Cables)

GUN POD ASSEMBLY

The gun pod is mounted to the universal pylon on the left side of the aircraft with standard 14-inch pylon lugs.

The gun pod provides a mounting point for the XM296 machine gun, and boresight adjustments points for weapon baseline to aircraft sighting mechanism adjustments. The gun pod is comprised of a:

gimble ring assembly
diode assembly
cage assembly
top plate assembly
gun charger assembly
electrical wiring harness
electrical (gun firing) solenoid assembly
rounds count sensor switch assembly

GIMBAL RING ASSEMBLY

The ginbal ring serves as the mechanical interface between the machine gun trunnion and the gun cradle. It provides 2-axis movement for machine gun boresight adjustments.

DIODE ASSEMBLY

The diode assembly is mounted on the right rear inside the rear of the cage assembly. The diode assembly rovides signal surge protection for the gun firing solenoid.

CAGE ASSEMBLY

The cage assembly provides protective enclosure for the XM296 machine gun and mounting points for the electircal wiring harness, the diode assembly, and spent casing ejection chute. The cage assembly consists of a forward nose shroud assembly which minimizes aerodynamic drag on the aircraft, a mid-cage assembly, and an aft-cage assembly.

TOP PLATE ASSEMBLY

The top plate assembly provides a shock-attenuating and boresightable mounting platform for the .50 cal. machine gun, mounting points for the cage assembly, and lug assemblies for mounting the gunpod assembly on the universal weapons pylon ejector rack. It consists of the top plate, two lug assemblies, and the gun carriage assembly. The gun cradle absorbs the recoil forces generated during weapon firing through its recoil adapter assemblies. The recoil forces are reduced to about 5-percent from those felt when the maching gun is fixed-mounted.

GUN CHARGER ASSEMBLY

The gun charger attaches directly to the machine gun receiver. It provides for remote charging of the gun; full aft and release (load/recock), full aft and latched (unload/safe).

ELECTRICAL WIRING HARNESS

The electrical wiring harness provides electrical signal interface between gun pod components (gun charger, gun firing solenoid, diode assembly, and rounds count sensor assembly) and the aircraft (via the .50 cal. umbelical harness). It also incorporates limit switches for the control of charger motor dirve signals.

ELECTRICAL (Gun Firing) SOLENOID ASSEMBLY

The solenoid is mounted on the backplate of the XM296 machine gun. It provides the means of electrically/remotely firing the machine gun. The solenoid is adjustable for setting timing of the machine gun.

ROUNDS COUNT SENSOR SWITCH ASSEMBLY

The rounds count sensor is mounted to the right rear side of the receiver. The sensor is a proximity switch which senses cycles of the breech bolt (pin).
