BMW Sauber F1.07 - rear wing revisions (尾翼技術分析)

Source: www.formula1.com

For Brazil, BMW have adopted a rear wing profile with a double curve, bending upward at the extremities. This solution raises dowforce at the rear without a significant increase in drag, hence leaving the car's top speed unaffected on the long uphill straights of Interlagos.

BMW 在Interlagos所使用的尾翼前端有兩個向上折彎的曲線，這樣作可以增加車身後段的下壓力卻不產生阻力，以避免影響到上坡直線中的尾速表現。
