Abstract
Openings in a muzzle brake provide recoil inhibition and impulse noise attenuation by redirecting the propellant gases to the external environment. A turning vane aggressively turns and redirects the propellant gases in a rearward direction to counter the recoil of the weapon system. An angled baffle provides a physical barrier to redirect propellant gases rearward to provide additional force to counteract the recoil force. Attenuation slits mitigate blast overpressure by producing a fluid barrier of high velocity propellant gases directed radially away from the muzzle brake. The fluid barrier from the attenuation slits interacts with the redirected propellant gas from the turning vane and the angled baffle and redirects the counter recoil gases away from the crew.
