| 摘 要： | 基于全速势方程，完成了超临界翼型设计。首先分析了最优化设计和反设计两种常用的翼型设计方法的特点。综合考虑两种方法的利弊，选用最优化设计法。结果显示，设计理论和实施方法完全适合现代翼型设计，设计结果可以满足设计指标要求，诸如巡航状态下的升力系数、阻力系数、升阻比、攻角、翼型最大厚度及厚度位置、巡航效率、压力分布形态、激波强度等等。

| Abstract: | aerodynamics design of supercritical airfoil is studied base on full potential equations in this paper, constrained design and inverse design method are analyzed, and constrained design method is applied to supercritical airfoil design. Results indicate that, the design method of this paper is appropriate, and the supercritical airfoil designed is meet design requirement on most of design target, such as cruise lift coefficient, cruise drag coefficient cruise angle of attack, lift drag ratio, pressure distribute, shock intensity, airfoil maximum thickness, cruise efficiency, and so on. |
