| 摘 要： | 为改善带涡襟翼的细长翼的升阻特性,在其上附加了前端襟翼和后缘襟翼。通过前端涡(前端襟翼上产生)和前缘涡(涡襟翼上产生)相互作用对气动特性影响的研究,得到能够改善升阻特性的方法。结果表明,涡的相互作用对涡的产生和发展有很大影响,因而影响细长翼气动特性。附加前端襟翼和后缘襟翼是必要的。由此得到既能增升又能减阻的前端襟翼偏转角。

| Abstract: | In order to improve the aerodynamic characteristics of vortex-flapped slonder wings, the apex-flap and trailing-edge flaps are added on them. Through studying the interaction between apex vortices and leading-edge vortices, a way is found to improve the aerodynamic characteristics of slender wings. Results show that the vortical interaction has a great influence on vortical production, movement and aerodynamic characteristics of slender wings. By controlling the deflected angle of the apex flap, the drag will be reduced and the lift increased. So the method of employing apex flap and trailing-edge flaps in combination is effective in enhancing the aerodynamic characteristics of slender wings. |
