After receiving the results of aerodynamic tests in MIRA wind tunnel, performed by the invitation of Niche Vehicle Market, we would like to share with motorsport fans what we achieved.
The tests began with a coefficient of aerodynamic drag of 0.5, which is significantly higher than that of road cars. This is due to the fact that all aerodynamic elements carry downforce, and so create drag .
The purpose of the test was to find the optimal relationship between these two parameters – to balance the tension forces of the front and rear axle.
The tests began with a coefficient of aerodynamic drag 0.5 and pitch strength 73% on the front axle and 27% – on the rear. It became clear that there is too much compression in front of the vehicle and must be processed in order to increase the load at the rear.
“After several hours program, which took place in various types of experiments and tests with different position of the rear wing and different rear wings, we achieved a result that is very satisfactory for us.” Said Rosen Daskalov
The end result is a reduction in aerodynamic drag coefficient at 0.43 and distribution of the pressing force to front and rear axle of 47% front and 53% rear.
Working with aerodynamic devices and reduce drag we earn another 10 hp.
Another interesting point during the test was the smoke test, which shows the movement of air around and over the car and gives guidance on where to obtain zones of compression, where are the places with turbulence and low pressure areas.
“Thus, once again we checked whether the calculations we have done, work in real conditions.” explained Rosen Daskalov
He expressed gratitude to the Niche Vehicle Market and MIRA for their assistance and an intention to work together in the future.
