Aerodynamic testing?

Aerodynamic testing?

Postby master6 » Mon Apr 26, 2010 10:21 am

I was on another site, and the thread was about improving time trial results by various methods, when I saw this:-



"Don't forget to work hard on your position as well. Maybe strap your self and a set of scales to the roof of your car. Get your mate to drive at 100km/h and move around until you can get the smallest reading on the scales. Obviously you'll have to set it up so that the scales are vertical and behind your back wheel."


I am not sure whether the poster was speaking in earnest, however, at worst, many silly ideas turn out to be usefull. The method could be modified to towing with a long line, for those who are scared of heights.
Can you envisage a test day, perhaps on the flats outside Richmond? Might be nice if any members of law enforcement agencies were elsewhere, however anyone involved in the medical profession could be put to good use!

There are more practical, accurate and safer ways to perform aerodynamic testing.

Did they have a roller trainer on the car roof?
I think: Find hill, assume position, ride down, check top speed, repeat - with different position would be easier and safer way to find best aero position.

Hey Spork, we test going down Ten Mile Hill the same way, no pedalling when at the top and roll down. its interesting to see people with crazy aero posistions.
