Abstract
A broach recoil mechanism includes an arresting cartridge and a broach having plural cutting surfaces. The broach is disposed on the exterior of the barrel of a weapon. As a projectile is fired from the barrel, the barrel recoils, moving toward the arresting cartridge. The broach engages the arresting cartridge, shaving off pieces thereof, slowing progress of the barrel while transferring the recoil load to the hull of a unmanned underwater weapon containing the weapon.
Claims11
An apparatus comprising a broach recoil mechanism, wherein the broach recoil mechanism mitigates effects of a recoil load on a weaponized unmanned underwater vehicle (UUV), the broach recoil mechanism comprising:
- a broach, wherein the broach comprising a plurality of cutting surfaces of increasing height disposed on an external surface of a barrel of the weaponized UUV;
- an arresting cartridge, the arresting cartridge comprising a material suitable for broaching via the broach;
- a sleeve, wherein the sleeve receives the arresting cartridge, and the sleeve and arresting cartridge are concentrically arranged with respect to the barrel, and suitably dimensioned so that the barrel moves longitudinally therethrough when a projectile is fired from the barrel;
- and
- a recoil load-bearing collar, wherein the recoil load-bearing collar is physically coupled to the sleeve and to a hull of the UUV, the recoil load-bearing collar thereby transferring the recoil load of the barrel to the hull.
An apparatus comprising a broach recoil mechanism, wherein the broach recoil mechanism mitigates effects of a recoil load on a weaponized unmanned underwater vehicle (UUV), the broach recoil mechanism comprising:
- a broach, wherein the broach comprising a plurality of cutting surfaces of increasing height disposed on an external surface of a barrel of the weaponized UUV;
- an arresting cartridge, the arresting cartridge comprising a material suitable for broaching via the broach, wherein the arresting cartridge is supported in a fixed position with respect to the barrel, and wherein:
- when a projectile is fired from the barrel, the barrel moves longitudinally in a direction opposite to a direction of travel of the projectile, and wherein, after an amount of travel of the barrel that provides sufficient time for the projectile to exit the barrel, the cutting surfaces of the broach engage the arresting cartridge, causing the barrel to slow due to broaching of the arresting cartridge and a transfer of the recoil load from the barrel to the UUV.
A method for transferring a recoil load from a barrel of weapon in a UUV, the method comprising:
- sliding a barrel towards an arresting cartridge in response to firing a projectile from the barrel, the barrel having a plurality of cutting surfaces of increasing height disposed on an exterior surface thereof;
- and
- engaging the cutting surfaces and the arresting cartridge, the arresting cartridge coupled to a hull of the UUV, engagement of the cutting surfaces and the arresting cartridge causing the barrel to decelerate and the UUV to accelerate as the recoil load is transferred from the barrel to the UUV, and wherein before the cutting surfaces and the arresting cartridge engage one another, the barrel moves a first distance that provides sufficient time for the projectile to exit the barrel before the cutting surfaces and the arresting cartridge engage one another.
