This year's fairing is a complete redesign - I can't give away all the awesome specs and how they compare to last year's - but when you put them side by side, the differences are significant  That said, I'm happy you liked our work 
That arm powered vehicle really needed someone with a big buff upper body - something not so common among engineers :/ It was well build though
Will you be at the next event April 25?

it looks like you're going from a trike back to a recumbent. I won't be at competition, i graduated and moved to Kentucky. The handcycle was designed for Paraplegics and lower limb amputees, they just thought it would be cool to bring it to competition. and they did well, that whole original idea thing. but this years will hopefully be alot better. last year's cycle was built before that drivetrain had ever been installed in a cycle so it wasn't positioned correctly in the frame b/c we didn't know where the best spot should be. the HPV's cycle topped out at 11 mph, i could easily get mine up to 16 mph and then i ran out of gears.

Just wanted to take a moment and let my team mate say something...
Safety is something we all should sometimes think about...

Great photo.
I am sure that Budweisser is a healing tonic and in no way was involved in the original accident.

Trebuchet,
Was that your HPV fairing video on Instructables.com? If so, thanks for posting! Our Solar Car team has been using some of your methods for building our wheel fairings. Good luck in your competition.

That makes me happy Yes, that's me
Do you, by any chance, have a team website? --- do0h! Just saw your signature

Update!
Direct link to page 2 update post.

It looks awesome... And yes, I'm intentionally NOT posting pictures of the whole thing in its current configuration. This will come soon.

Ahh man, you can't post that and not provide a link - or at least pictures That sounds AWESOME! Is it the sort of thing you have to wear SCUBA (I'm padi certified, and I've always wanted to ride in something like that )?

This is an amazing project, and an inspiration to us all. If we could have aero nuts like the people on this website designing our cars, we would have seen 100 MPG production cars decades ago. We will be rooting for you on the 25th, good luck!

Have you and your team even considered inverting that design laterally?
I'm a bit late on this thread, so I apologize if this has been answered before... The air fluidity from the front clearly showed a LOT of turbulence in the sidewall midsection. If you inverted your design, you'd reduce that drag to a fraction of what it is.
Granted, you'd increase turbulence at the rear, but I would think that it would be a much smaller at that point.

I accidentally ran CFD the simulation backwards on my first run (for some reason the coordinate system was/is reversed).... While the oil flow lines looked nicer - there was slightly more drag (but only slightly).... But, even so - we wouldn't fit! It's really hard to fit a human - pointing forward - with pedal path considerations AND be aerodynamic The prone position (laying on your front - head first) would be more aerodynamic, but the prone position isn't as intuitive as sitting - a primal task

5/3 - So What the Hell Happened?
It's done! And We competed But,I'm getting ahead of myself...
So fairing putty was applied to the seam, to get it nice and smooth...
Then the frame and fairing were primed...
Here it is mounted together
How are they mated? Set screw collets (aluminum on the fairing side, steel on the frame side) with carbon strengthened rods. The Al collets were welded to small AL plates which were then laid up inside the fairing.
On the way to WI, I made dinner - Brats! Cooked in ecomodder fashion - economically and efficiently - using waste exhaust heat!
I stopped in a hotel on the way up to Madison... I love my bike
Oh, so what does it look like? You ask....
Tuft Testing...
Double hinged hatch - open for show or entry/exit position Butt goes in first, then legs swing in. It's a little tight, but I can do this movement no sweat
Yarr! Caution: Student Driver
Post Event... Now we don't need to worry about taco'ing a wheel, so here's some trike two wheel action! I got good at holding a line and doing circles on two wheels
More soon, I'm getting pictures from the whole event soon...
Oh... Not sure on final placement results... But we got Second in Design! Woo Hoo! Design report will be posted soon too
