| 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. |
