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.
