100 knot submarine?

[Sean B]

Here is a neat piece of new technology, coming soon to a naval base near you. It's a submarine that blows gases in front of it as it moves along, so that it travels in a bubble, which has almost no drag. I wonder where all the gases that they inject in front of it come from. Next time you see a bubble trail moving across that water at 100 MPH , you'll know what it is. Now if I could only figure out how to blow enough air under my boat hull to do this....oh yeah, it would sink Check it out: Supercavitation Sub Illustration And here: Project Goals The Underwater Express Program will demonstrate stable and controllable high-speed underwater transport through supercavitation. The intent is to determine the feasibility for supercavitation technology to enable a new class of high-speed underwater craft for future littoral missions that could involve the transport of high-value cargo and/or small units of personnel. The program will investigate and resolve critical technological issues associated with the physics of supercavitation and will culminate in a credible demonstration at a significant scale to prove that a supercavitating underwater craft is controllable at speeds up to 100 knots.

That's pretty cool. I hope they actually can do that someday. I can get some pretty super cavitation in reverse if I give it much throttle..

Just what I was thinking.
