变前掠翼无人机翼身连动机构设计

针对变前掠翼无人机设计了一种翼身连动机构,使无人机能够根据任务需求,在直机翼、前掠翼、三角翼之间进行气动布局转换,从而在整个任务飞行过程都能达到性能最佳.该连动机构为一环形卡槽式结构,在连接翼梁的卡槽两端布置有4个油腔,通过电磁活门控制高压油液驱动翼梁旋转,从而完成机翼的转换.该结构使翼升力在翼根的应力集中通过环形槽两侧的作用点被分散,避免了因翼根加固所导致的结构增重.

A Design of Wing-Body Revolved Mechanism for UAV with Variable Forward-Swept Wing

The Unmanned Aerial Vehicle(UAV) with variable forward-swept wing is a new design concept,which integrates the advanced aerodynamic characteristics of orthogonal wing,delta wing and the forward-swept wing.The best performances under different mission demands can be achieved through changing the wing position among the three said configurations.The design of wing-body revolved mechanism,as a key technique,must be hard enough to suffer the lift and moment during varying wing,moreover,the fuselage can not be o...
