摘要: 以比例为1∶3的F1方程式赛车后升力翼为研究对象,研究了后升力翼攻角变化对F1方程式赛车气动阻力和气动升力的影响规律.在攻角为12°时,气动升力与气动阻力的比值的绝对值达到最大,此攻角就是F1方程式赛车后升力翼的最佳攻角,模型风洞试验验证了这一结论.Abstract: Taking the rear lifting airfoil of scale of 1∶3 F1 racing car as the object of study, the influence law of angle of attack of rear lifting airfoil on the aerodynamic drag and lift of the F1 racing car was researched. When the angle of attack is 12°, the absolute value of aerodynamic lift and drag ratio reaches the maximum, and the angle is the optimum angle of attack of rear lifting airfoil for F1 racing car. Model wind test validated the conclusion.
