traînée de culot / prise d'air latérale Explanation: sans contexte, il est impossible de voir le lien entre ces deux notions "La principale traînée (de l'ordre des 2/3) est la « traînée de forme » (ou de profil)3. Deux principales raisons physiques expliquent l'existence de cette résistance ; la première est due à l'augmentation de la pression à l'avant du véhicule tandis que la seconde est due au vide partiel laissé par le véhicule après son passage formant une traînée de culot ayant pour conséquence de l'« aspirer » dans la direction opposée à son mouvement5." http://fr.wikipedia.org/wiki/Aérodynamique_automobile http://philippe.boursin.perso.sfr.fr/pdgaero.htm -------------------------------------------------- Note added at 1 day7 hrs (2015-01-31 15:05:33 GMT) -------------------------------------------------- Ferrari 458 ("cars & trucks") "Thanks to innovations from Ferrari's F1 experience, and extensive wind tunnel testing, the 458 produces better cooling, less drag, and increased downforce. The former large side intakes behind the doors have disappeared within the C post, leaving a smooth open span that draws your eye up and over the rear shoulders. It also creates a clear aerodynamic path by which airflow is directed within the bodywork. New inlets at the headlights direct airflow through the front wheel arches, and small winglets in the front intakes help to reduce drag and generate downforce, as well as increase cooling for the repositioned radiators. The flexible winglets actually deflect downward as much as 20mm at speeds starting at 125mph, further optimizing directional airflow, and reduce lift over the front fenders by a full 40 percent. A new flat underbody with engine cooling ducts, and rear diffuser also show a marked increase in overall aerodynamic efficiency. Even the transmission radiators, now located in the tail, act as spoilers, creating an FXX-derived base bleed effect. The resulting aero-sharp styling and optimized aerodynamics provide a slippery 0.330 drag coefficient (down from 0.343), and up to 795 lbs of increased downforce at 200mph. " |
