Abstract
The present invention includes a means to sustain a rocket torpedo's supercavation envelope to enhance the speed, maneuverability and resistance to percussion based counter measures. The invention includes machines using those aspects of the invention. The invention may also be used to upgrade, repair, or retrofit existing machines, using methods and components known in the art. The present invention comprises a porous plate technique never associated with torpedo design. This approach differs from previous efforts to apply porous plate designs to surface ships and differs as a proportional gas flow is achieved to sustain supercavation during all aspects of a torpedo travel to include but not limited cruising, diving, surfacing and while executing turns of any turning radius.
Claims1
A rocket torpedo having a self contained rocket motor and a cavitation induction device for creating a flow of gas at a forward tip of said torpedo to thereby create a supercavitating gas envelope surrounding said torpedo during propulsion, the improvement comprising,
- multiple longitudinal gas channels running along the torpedo, each of said gas channels covered by a porous material such that any gas injected into the gas channel will eject through said porous material,
- means for selectively injecting gas selectively into each gas channel to thereby create a flow of gas into the selected gas channel and a flow of gas through the porous material covering said selected gas channel,
- where the ratio of the gas flow at the tip of the torpedo to the flow of gas through the porous material of the selected gas channel is defined by the equation,
- E
- ∝
- π

-
- L
- 2

- (
- θ

- where L is the length of the torpedo, D is the diameter of the torpedo and Θ is the turning angle of the torpedo where 0 degrees denotes straight travel.
