Abstract:
1. A supercavitating projectile comprising: a body having a forward end and a rear end; a combustion chamber interior to said body; a solid propellant loaded within said combustion chamber; a pathway defined through said solid propellant wherein said pathway has an axis collinear to a longitudinal axis of said body; a first nozzle with a fluid connection collinear to said pathway and to an exterior of said projectile at the forward end; and a second nozzle with a flow area larger than said first nozzle with said second nozzle having a fluid connection collinear to said pathway and to the exterior of said projectile at the rear end; wherein said propellant is combustible to produce gases that fluidly direct through said first nozzle to form a ventilation bubble forward of said projectile and producing gases that fluidly direct through said second nozzle to form a jet as a propellant to said projectile allowing the formed ventilation bubble by said projectile to act as a supercavitator for said projectile.
