Abstract: A gun barrel with piecewise helical barrel fluting comprises a single start non-stop feature of alternating and intersecting right hand and left hand helical segments. Piecewise helical barrel fluting combines the ease of manufacture of a single start fluting with the improved performance benefits of a multi-start approach, namely increased barrel stiffness and resulting performance with respect to firing accuracy and firing precision.

Abstract: A remote weapon system (RWS) for an unmanned ground vehicle (UGV) includes a dedicated weapon, multi-axis gimbal and ammunition handling capabilities with all operations functioning remotely and wirelessly. The RWS comprises system-level and component-level safety features which preclude the weapon of the remote weapon system from being operable if removed from the remote weapon system.

Abstract: A remote weapon station (RWS) system for an unmanned ground vehicle (UGV) includes a dedicated weapon, multi-axis gimbal and ammunition handling capabilities with all operations functioning remotely and wirelessly. The RWS system is a gas powered, or self-powered, belt fed, rotating bolt lock weapon. In addition, the RWS is man-portable and air-droppable as the major subsystems may be latched together in the field without tooling or needing to make electrical connections.

Abstract: A power generation assembly for a weapon system converts waste energy from a firing event to electric power. The power generation assembly directs expanding burning propellant gasses within the weapon system into a turbine array to generate electric current. The electric current is rectified to trickle charge a battery bank which then powers the weapon system.
