Abstract
Powder gases issuing from the muzzle of an aircraft-mounted gun are initially deflected to one side of the line of fire by a mouthpiece in the form of a length of pipe coaxially mounted directly in front of the muzzle and having an elliptical mouth extending all across it and along it from a pointy front end of it to a short distance in front of its rear end. The gases are further deflected to a discharge direction away from sensitive parts of the aircraft by a set of guide plates arranged outside the mouthpiece and spaced apart at regular intervals along the line of fire. Inner surface portions of the guide plates, proximal to the extended axis of the gun barrel, are parallel to the direction of local gas flow out of the mouthpiece, and the guide plates are curved so that their outer surface portions, which cooperate to define slot outlets, extend in said discharge direction and are parallel to one another.
