Cool
Underwater glider AUV

I was having lunch down at Scripps Institution of Oceanography the other day and they were bringing out some of the toys to display at a luncheon for the big-wigs. This one caught my eye.
No propulsion from what I could see, just some control surfaces on the trailing edge (elevons/flaps). It had some stickers on it labeled "Department of the Navy Science and Technology". I couldn't find anything about it on the inter web, but there are some other underwater gliders out there, like the XRAY

Maybe you can slope-float this thing in the upwelling currents of the continental shelf.

When I was a kid, 60 years ago, I remember building a plastic plane (military, prop job).
Poked holes in it to keep air bubbles from accumulating, Balanced with lead sinkers. Rubber band power for plastic prop. Flew real good underwater, including takeoff from bottom, flight as high as ceiling (water surface), and glide back down to bottom.
Was kind of critical about water turbulence. Everything in SLOW motion.

Looks to me you were taking your "fluid" mechanics seriously from an early age!

Are you sure Joe Manor is not involved?

Yeah, I'm quite taken a back that has not been asked.

Fascinating. Was the plastic plane designed to do that or was that your idea? My Dad (1947 model); has told me about some really interesting toys he had as a kid. He had a "jet", essentially a rocket with wings. You would prime the fuel cell and set the contol surface(s) so that it would climb up in a spiral on rocket power and then glide back down. He also had a steam engine that they would use to drive all sorts of things. A boat, a car, a small lift with a clutch system. Fantastic!
