[aerohead]

I've done about as much damage as I can on 'Hammerhead.'
* Factoring in the 'upright' windshield, the drag climbed to Cd 0.3766.
* Factoring in the 'catamaran' type wheel fairings, they brought the Cd up 0.4192.
* The photovoltaic 'canards' on either side of the cabin will degrade Cd a bit more, but without actual exterior dimensions, it's folly to attribute any quanta to them, other than an estimated Cd 0.83, based upon their frontal area, plus an interference 'excrescence' penalty.
--------------------------------------------------------------------------------------
These numbers are just a 'shootin' from the hip' estimate.
I found test examples from 14-sources which isolated single attributes to specific 'features' drag, empirically tested in the past, and converted their observed 'counts' penalty, to a percentage Cd degradation.

I 'like' ALL solar race cars, and I'm glad for the entire student body and teaching staff involved in the ' Hammerhead' project.
