![]() At the simplest level a wing generates downforce due to its profile accelerating airflow on its lower surface in relation to the flow over the top surface. Why is the F-Duct beneficial? Basic wing theoryįirst we need to look at some basic aerodynamic theory regarding wing profiles and lift/drag ratios. This speed advantage appears to have given the team the upper hand at the Shanghai circuit, Racecar decided to investigate the theory behind the new system. Remain immobile in relation to the sprung part of the car. The car (rigidly secured means not having any degree of freedom) Must be rigidly secured to the entirely sprung part of. ![]() With the basic idea being that the driver is able to alter the airflow over the rear wing, without infringing regulation 3.15 (below), and in doing so gain a speed advantage on straights.ģ.15 Aerodynamic influence : With the exception of the coverĭescribed in Article 6.5.2 (when used in the pit lane), the driverĪdjustable bodywork described in Article 3.18 and the ducts described inĪrticle 11.4, any specific part of the car influencing its aerodynamic ![]() When McLaren’s F-Duct system first appeared in pre-season testing it was hailed by many a a true stroke of genius, a classic example of out-thinking the regulations.
