A baffled muzzle brake and seal system fur submerged gun operation includes a muzzle brake chamber mounted to the muzzle of a submerged Tun barrel. A baffle assembly mounted within the chamber deflects the propellant gasses produced by operation of the gun and sabot fragments into an annular chamber surrounding the baffle assembly while allowing passage of a projectile through the assembly. A valve seal in the muzzle end of ...
The present invention relates to an underwater weapon having a barrel with an opening through which a projectile is discharged. The weapon further has an apparatus for pressurizing the interior of the barrel to a pressure greater than the ambient pressure to keep water from entering the gun barrel at any point around the circumference of the muzzle opening. The pressurizing apparatus includes a source of gas, a pressure regulator ...
A sealing apparatus which may be mounted on multi or single barreled guns is disclosed to provide a watertight seal on an underwater gun. The sealing apparatus comprises a sealing plate connected to a gun barrel and a muzzle seal which fit on the muzzle of the gun barrel and frictionally engages the sealing plate. The sealing plate includes a firing aperture which aligns with the gun barrel when the ...

The present invention relates to an underwater weapon having a system for sealing the opening of a gun barrel to prevent the ingress of water. The sealing system includes a non-metallic or metallic tape for covering and sealing the opening and a mating surface on the gun barrel against which the tape is seated to prevent the ingress of water. The sealing system further includes sprockets for advancing the tape ...

In a fluid such as water the direction of a vessel is controlled by a fin having at least one fixed chordwise segment and at least one cantilever mounted movable segment secured to the fixed segment by a backbone or spine spring at the neutral axis, and by differently tensioned control wires that are used to achieve camber variations under the influence of the vessel's control system. An elastomeric skin ...
