Short recoil impulse averaging weapon system
First Claim
1. A weapon system for firing a round from a belt of rounds, the weapon system comprising:
- a receiver;
an operating group configured to operate the weapon system through a charged condition, a firing condition, and a recoil condition, the operating group comprisinga barrel extension at least partially housed within the receiver and arranged to axially translate relative to the receiver;
an operating rod (op-rod) assembly at least partially housed within the barrel extension and arranged to axially translate within the barrel extension between the charged condition, the firing condition, and the recoil condition; and
a bolt assembly coupled to the op-rod assembly and at least partially housed within the barrel extension and arranged to axially translate within the barrel extension between the charged condition, the firing condition, and the recoil condition;
a barrel coupled to the barrel extension and defining a chamber and a bore,wherein the op-rod assembly and the bolt assembly are interlocked such that the bolt assembly is limited in axial movement by the op-rod assembly to provide a redundant containment of the op-rod assembly and bolt assembly within the barrel extension;
a gas accelerator with a first end coupled to the barrel and a second end coupled to the op-rod assembly;
a buffer assembly comprising a 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 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.

12. A weapon system for firing a round from a belt of rounds, the weapon system comprising:
-
a receiver; an operating group configured to operate the weapon system through a charged condition, a firing condition, and a recoil condition, the operating group comprising 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 at least partially housed within the barrel extension and arranged to axially translate within the barrel extension between the charged condition, the firing condition, and the recoil condition; and a bolt assembly coupled to the op-rod assembly and at least partially housed within the barrel extension and arranged to axially translate within the barrel extension between the charged condition, the firing condition, and the recoil condition; a barrel coupled to the barrel extension and defining a chamber and a bore; a gas accelerator with a first end coupled to the barrel and a second end coupled to the op-rod assembly; a buffer assembly comprising a 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, wherein the barrel comprises a quick-release assembly that includes a lock projection on the barrel, first locking lugs on the barrel, second locking lugs on the barrel extension, and a lock surface on the barrel extension, and wherein, in a locked position, the first locking lugs and the second locking lugs cooperate to prevent relative motion in an axial direction and the lock projection and the lock surface to prevent relative motion in a circumferential direction. - View Dependent Claims (13)
