Re: [PSUBS-MAILIST] Interest in your project

Paul,

The starting point on the profile was a NASA low drag profile. I then looked at fast marine life such as the Orca and tried to incorporate some of their features into aircraft life control surfaces. The aft control surfaces are mounted on an articulated jet ski nozzle that has small hydraulic cylinders the control pitch and yaw movements. The port and starboard ailerons are hydraulically coupled and can be controlled with a joystick via the PLC. These give me roll control. My goal with the design is to be able to fly the boat underwater with the same type of stick and rudder pedal movements you would have in a small plane. The design objective of the boat is far removed from a more conventional psub like the k boats.

The ultimate destination for the boat is the caribbean where the water clarity can support the speed.

I have to second that "Wow!" Nice engineering.

Cliff, how did you design the hydrodynamics? Some aircraft techniques? I see a prop, wings, control surface, etc...

And what kind of water clarity are you aiming for when testing that top speed?! :-) Or rather, I didn't see any sonars spec'd in your description.
