Abstract: An omni-directional recoil energy absorption mechanism has a slipping disk supported by a support plate carrying a weapon; and a cover plate covering the slipping disk and capturing it to create a sandwich structure of cover plate, slipping disk and support plate. Bolts act in conjunction with pressure springs to press the cover plate to the slipping disk toward the support plate and create friction forces in a plane of the slipping disk. Tension springs connect the slipping disk to the support plate under recoil force configured to return the slipping disk and the weapon to an initial position, in a center of the support and cover plates. The springs are preloaded to a pre-defined level to oppose, flexibly, the recoil forces in any vertical and radial directions, while absorbing the recoil energy by allowing the slipping of the slipping disk in between the cover and support plates.

Abstract: The present invention will provide a flexible secondary weapon mount that can quickly and easily attach and detach to an OGPK surface and retain/eject a secondary weapon quickly and easily. Furthermore, the present invention is designed to operate with common weapon mount pintles for compatibility. This is accomplished by utilizing a base, support levers, and a ball lock retention pin for retaining he secondary mount to a surface and retaining/ejecting the secondary weapon quickly and easily.

Abstract: A weapon may include a translatable recoil mass and two translatable counterweights disposed on opposite sides of the recoil mass. Each counterweight may have a mass that is substantially one-half a mass of the recoil mass. A pair of racks may be fixed to respective ones of the counterweights and a second pair of racks may be fixed to opposites sides of the recoil mass. Pinions may engage the counterweight and recoil mass racks. A receiver may be fixed with respect to the recoil mass and the pair of counterweights. The directions of translation of the recoil mass are substantially opposite directions of translation of the two counterweights.

Abstract: A gun comprising: a generally tubular barrel defining a barrel axis and having an external barrel surface about the perimeter of the tubular barrel a cradle having a cradle bore for accommodating a section of the barrel wherein the barrel is slidably mounted in the cradle bore such that the barrel can move relative to the cradle along the barrel axis across a range of barrel positions and wherein an interface defined by the slidable contact between external barrel surface and the cradle bore—i) prevents rotation of the barrel relative to the cradle about the barrel axis; and ii) is maintained at a single section of the cradle over the entire range of barrel positions.

Abstract: A weapon mount including a housing through which the weapon translates when fired, a conversion subsystem configured to convert translation of the weapon when fired into rotational motion, and a braking subsystem for resisting rotation of the conversion subsystem.

Abstract: An isolation system for a sensitive component or apparatus affixed to a mortar tube comprising a barrel mount assembly which supports two parallel shafts. A plate parallel with each axis of the two shafts positions four bearing carrier blocks, two each containing a sleeve bearing which rides on each of the shafts to allow the plate assembly to slide freely along the length of the shafts and support an isolated cage. During firing, the travel vector is decoupled from the cage by the shafts as they move with the barrel through the bearings leaving the cage assembly in free space. The cage then accelerates under the force of gravity over the distance of the displaced travel of the shafts back to its rest position landing on steel springs or dampers, each on a shaft and seated against the lower flange end of the barrel mount assembly.

Abstract: A recoil buffering apparatus for use with an artillery gun of the type comprising a breech assembly (15) connected to a barrel (12), the breech assembly (15) having a firing mechanism for firing a projectile through an open end of the barrel (12). The recoil buffering apparatus comprises a recoil buffering means adapted to be fixed to the barrel (12) and movable therewith during recoil action of the barrel (12) caused by firing of the projectile, and a support means associated with the recoil buffering means for supporting the recoil buffering means and thereby supporting the barrel (12) and breech assembly (15) through the recoil buffering means. An elevating apparatus and a traversing apparatus for an artillery gun are also described. The artillery gun can also be provided with a muzzle brake (11).

Abstract: A weapon having a barrel (3) supported in a cradle (2) for axial recoil movement, and having a breech block wedge (7) displaceable, transversely to the barrel axis (6) by a control unit (11) connected to the cradle and acting on a piston rod (8). The control unit (11) includes a spring-loaded shift rod (13) aligned with the piston rod (8), a spring-loaded control rod (15) aligned with a control cam (10) secured to the breech ring (4), and a detent pawl (17) that can be pivoted by a cam (16) from a blocking to a release position. The piston and shift rods (8, 13) are disposed such that during forward motion of the barrel (3), the breech block wedge (7) is already opened by axial displacement of the rods (8, 13) before the control cam (10) displaces the control rod (15).

Abstract: A machine gun and associated armament apparatus, including an ammunition box for supplying belted ammunition to the gun, are exteriorly supported on a landing gear sponsor tow plate of a helicopter, adjacent a cabin area gunner's window, using a specially designed pintle support structure. The machine gun is horizontally rotatable about a vertical azimuth rotation axis which is forwardly tilted and substantially parallel to the similarly tilted rotor mast axis. The gun's upward firing elevation angle is limited to 1.5 degrees when the gun is pointed forwardly. However, due to the forward tilting of the gun's azimuth rotation axis, its maximum upward firing elevation angle automatically increases as the gun is swung rearwardly, thereby desirably increasing the gun's firing range to the side and rear of the helicopter while at the same time automatically maintaining the bullet path of the forwardly pointed gun safely below the forwardly drooped operational rotor tip path.

Abstract: A damped spring device for a firearm is disclosed. The damped spring device includes a housing, a cylindrical outer tube fixed to the housing and defining a cavity, and a cylindrical barrel slidably disposed within the outer tube cavity such that the outer tube and the barrel define therebetween an annular space. The barrel is moveable longitudinally through a portion of the cavity between a rest position and a recoil position in response to the firing of the firearm. A prestressed elastomeric spring is disposed within the annular space and operatively engages the outer tube and the barrel for biasing the barrel toward the rest position and for braking the relative movement between the barrel and the outer tube.
