Mach number than predicted by wind tunnel data. The 996 had a drag coefficient of resulting from hours spent in the wind tunnel. Initial results of the Caltech wind tunnel tests were disappointing. This model was initially used for a series of wind tunnel tests. Ten design proposals were evaluated with five designs emerging after intensive wind tunnel testing. A total of 1,400 hours of wind tunnel testing was completed by 2008. Wind tunnel tests continued through this period. The women worked on the data coming from wind tunnel and flight tests. Aerodynamics for the car included over 1,300 hours of wind tunnel analysis. It was the first car to be designed in a wind tunnel. None developed beyond prototypes or wind tunnel models, save for the G5N. It is unknown to what extent the wind tunnel is used currently. Automotive aerodynamics is studied using both computer modelling and wind tunnel testing. There are many applications for boundary layer wind tunnel modeling. They assisted him with the construction work, computer simulations, and wind tunnel tests.
