摘要

This paper presents the experimental investigations of NACA0012 airfoil aerodynamic characteristics improvement by airfoil tail tailoring ( 30% chord part ) in low speed wind tunnel. Experiment Renolds number range is 4.9 ×10⁵ to 6.5 ×10⁵ , and the angle-of-attack range is -12° to 12°. The comparisons of experimental results show that: tail tailoring can increase both airfoil lift and lift-to-drag ratio in the positive angle-of-attack range; it can decrease airfoil drag in the negative angle-of-attack range.
