| 摘 要： | 以飞翼布局为研究对象,对常规和智能两种后缘襟翼模型进行了对比试验,在风洞中探索用智能材料植入机翼代替常规铰接式后缘襟翼的气动效益。本文给出了在北航D1风洞1/20半模模型对比风洞试验的结果,结果表明:在与常规襟翼相同偏角情况下,智能襟翼具有更大的增升效益;在常规襟翼失效的偏角情况下,智能襟翼仍能提供额外升力;在实验攻角范围内智能襟翼比常规襟翼平均增升20%以上。

| Abstract: | Comparative experiment has been carried out for conventional and morphing flaps in a flying layout,Which toke out the aerodynamic efficiency of conventional flaps and morphing flaps with smart material.This paper presents an overview of the results from the morphing aircraft,which was performed at the BUAA D1 wind tunnel.The results show that morphing flap could bring more performance gains of lift with the same flap deflections than conventional wing model.Morphing flaps could provide additional lift while... |
