Re: Genesis results

Hi
 
Tunnel test time runs out at about £2K per day, which includes the staff  and
sorting out the mounting (if not too complicated). They were suggesting a  
full size frame mock up, with the wheels rolling  in contact with the  rolling
road, to give more accurate results.
 
You could use anything for the experimental bodywork, including  polystyrene.
as long as you can attach it firmly enough. To make best use of the  tunnel,
you would need at least 4 different styles, and possibly a number of  
appendages. If developing a full size 'open' style vehicle you would need a  replica
rider as well, I suppose.
 
This sort of thing could be done with an advanced computer programme, which  
can sit and go through all the variables until it refines the best shape, but  
the best shape in electrons is not always the one that works on the road.
 
To test for side winds you may have to lift the vehicle clear of the  
floor......
 
Cd was  0.35 with the doors on, and 0.45 with the doors off.  Which sounds a
bit high to me, but was saved by a small frontal area. Could do  
better..........
 
Ride safe
