Re: [PSUBS-MAILIST] New World-Record Speed Set At International Human-powered Submarine Races; 'Batwing And Manta Ray-like' Power



Does anyone here know what kind and brand of water proof servos they used, as well as what computer system, and how it was kept water tight?

Omer 5 has a removable memory stick that the pilot plugs in. It has his individual preferences such as variable pitch settings and parameters governing the control surfaces. It also saves all sorts of parameters during the race for analysis on a poolside laptop. This way they make adjustments between runs. I saw data for a run and the interesting thing is that at the end of the 100m they were still accelerating.
 
The two crewmembers also have panels that give them real time feedback on a number of parameters using simple led arrays.
 
The sub is all fly-by-wire, with little servos moving the control surfaces.

Jay, Pic came through fine, as did Joe's link of the current crop. Cool stuff. I used to have a neighbor up here in PSL who was the ENGINE for FAU's sub for a couple of seasons. Can't remember his name, but that boy had some pins on him, let me tell you. And some lungs, no doubt. Vance

Vance,
Yes it is exciting.  The Omer Team has dominated recent races and will be very hard to beat.  I assisted with the first races in California held in a tow tank?water was extremely cold with visibility not being great but did get a chance to help set a world?s record speed with my alma mater?s team from FAU.  There is a lot of camaraderie among teams at the races but teams are really serious as you note.  Here is the only image that I have from the races, not sure if it will make it through the web server:

A skimmer afloat is but a submarine, so poorly built it will not plunge.

Jay, Exciting stuff. I used to do some beach work when Perry hosted this thing, and that was fun. But these folks seem REALLY serious by comparison, don't they? I'm looking forward to pictures of the new stuff from Canada. Vance
