| 摘 要： | 通过风洞测力实验研究了矩形Gurney襟翼对多操纵面飞翼布局无人机纵向气动特性的影响.升降副翼和襟副翼加装Gurney襟翼都会增加全机升力系数以及低头力矩系数.通过比较发现,升降副翼加装Gurney襟翼的增升效果好于襟副翼,外侧操纵面控制效果好于内侧.升降副翼和襟副翼分别组合加装Gurney襟翼会进一步提高增升效果,并且升力系数随着Gurney襟翼高度的增加而增加.鸭翼上加装Gurney襟翼可以减小全机低头力矩系数,因此鸭翼和升降副翼、襟副翼组合加装Gurney襟翼在线性段提高全机升力系数的同时,可以保持低头力矩系数增量基本为0,该特性对改善飞行器性能尤为有利.

| Abstract: | An experiment had been conducted to investigation the effect of different control surfaces with Gurney flaps on the aerodynamic characteristic of a multiple-control-surface tailless aircraft model.It is found that either the individual elevons and flaperons,or their combinations with Gurney flaps can increase the lift coefficient,while the drag and nose-down pitching moment coefficients are also enhanced inevitably.In contrast,when the canard wing is equipped with Gurney flaps,the lift and drag coefficients... |
