【摘要】 为确保二元翼型实验的精确度，一般都用测压的方法测量翼型的气动特性，即测量翼型表面的压力分布以确定翼型的升力和力矩特性，测量尾迹区的总压分布确定翼型的阻力特性。本文就如何处理尾迹区的测压数据来确保阻力测量的精确度及如何测出大迎角的阻力特性进行了一些探讨。更多还原

【Abstract】 In order to obtain the experiment result with high accuracy for high lift-drag airfoils,the method of surface pressure survey combined with momentum method is often used, i.e. surveying the surface pressure distribution to determine the lift and pitch moment characteristics,surveying the total pressure distribution in the wake to determine the drag. This paper introduces a process method of the pressure data in the wake to obtain the drag characteristics with high accuracy, and discusses about the drag measurement at high angle of attack.更多还原
