摘要

摘要: 碟形飞行器是一种小展弦比全升力飞行器,采用一种仿生的鱼鳍型小翼对绕碟形飞行器的诱导流动现象进行改善,削弱翼尖诱导旋涡,提高整机气动效率.应用高精度风洞试验和以该风洞试验数据为校验的数值模拟,对鱼鳍型小翼的作用进行了研究,从风洞试验和数值模拟两方面给出了评判.研究结果表明:鱼鳍型小翼对碟形飞行器的诱导流动现象有较大的改善效果.

Abstract: The saucer-shaped aircraft is a kind of all-lifting-vehicle with low aspect ratio. Bionic fin-shaped wing tips were used to improve the induced flow over the saucer-shaped aircraft and impair the induced flow separation, and then the aircraft aerodynamic efficiency could be increased. The high precision wind tunnel tests were conducted to investigate the induced flow improvement effect of the saucer-shaped lifting body, with the adopting of the fin-shaped wing tips. Numerical simulations basic on the high precision wind tunnel tests were also used. The results show that the fin-shaped wing tips could highly improve the induced flow over the saucer-shaped aircraft.
