An Experimental Study of an Intelligent Muzzle Brake

Conference paper


An investigation was made to study a novel aspect of muzzle brake design. It uses a concept which isolates and minimises the interaction of an expanding blast wave from the muzzle of a gun with a muzzle brake device, whilst at the same time maintains its function as a recoil impulse attenuator. The technique utilises the intrinsic energy of the exhaust gas flow to activate a set of active surfaces. During the gas ejection phase from a weapon launch, these surfaces become operative under the influence of the exhaust gas pressure, and function interactively with a muzzle brake surface to deflect some of the axial gas momentum. This effect produces a forward gas dynamic impulse by the brake and is subsequently contributing to the reduction of the overall recoil impulse exerted on a gun.
