Muzzle break with supersonic nozzle

摘要

A muzzle brake mounts to the barrel of a gun and reduces the recoil when the gun is fired. The muzzle brake comprises a supersonic nozzle including an expansion chamber configured to accelerate the propellant gases exiting the barrel of the gun and a reverser plate to at least partially reverse the flow of the propellant gases to reduce or mitigate recoil.

主权项

1. A muzzle brake comprising:
a supersonic nozzle adapted to attach to the end of a gun barrel, said supersonic nozzle including an expansion chamber having an inlet and an outlet, said expansion chamber being configured to accelerate gases exiting the end of the barrel when the gun is fired; a reverser plate spaced from the supersonic nozzle and configured to redirect the flow of the gases exiting the supersonic nozzle; an opening in the reverser plate for permitting a bullet exiting the barrel to pass through the reverser plate; and an annular opening between the supersonic nozzle and the reverser plate to allow the escape of the propellant gases exiting the supersonic nozzle.
