Subject: Corvette Fever Tests Corvettes In AeroDyn's Wind Tunnel by BrianCunningham on 2009/3/23 2:49:12 Another post worth bringing over here: http://forums.corvetteforum.com/autoc ... unnel.html#post1569403188 [QUOTE]SuperL98; Corvette Fever (May 2009) has an interesting article this month on Aerodynamics. They took Corvettes, from each generation, and tested them in the AeroDyn wind tunnel (Mooresville, North Carolina). http://www.a2wt.com  I dont think I can legally post the whole article, but here are the graph results. Data seams to be taken at 85 mph, and Passengers means they placed weight in the seats.   I put their CDA, Lift/Drag Ratio, and % Front Lift, into a spreadsheet and calculated values up to 200 mph. Just did the base model coupes, with passengers. Keep in mind this is just Aerodynamic Drag (from the data) and no rolling resistance.  And front and rear lift, again from their data.   Interesting stuff, if the data is believable? The C5 has the lowest drag. The C4 & C3 have the lowest rear Lift, even lower than the C6? Look how high the C4 drag coeff is 0.371 ? Anyway, hope this is interesting...... Yes, the early cars are: C1 is a 62 C2 is a 63 Split Window C3 is a 70 C4 is a 90 ZR1 AeroDyn has a few picture and a video of a C6 in the tunnel, on their web page.     http://www.youtube.com/watch?v=aduap_AS5j8 http://www.youtube.com/watch?v=aduap_AS5j8 http://www.youtube.com/watch?v=shcms4YnOh8 ;)[/QUOTE] |
