摘要
提出了一种分布式超声电机驱动的小型变弯度翼。分别对机翼的变形驱动方案和流场分布规律进行了仿真分析,研究了变弯度翼的变形驱动机构、高弹性伸缩蒙皮、分布式超声电机的协调控制等关键技术,并实现了小型变弯度翼的系统集成。风洞实验数据表明,分布式超声电机驱动的变弯度翼能够实现机翼在低速飞行状态下外形的智能变形驱动与控制,从而可以有效改善机翼的升阻气动特性。笔者研究的成功展开为压电精密驱动技术应用于流动控制探索了一条可行的技术途径。
A kind of small variable camber wing driven by distributed ultrasonic motors is put forward. The relation between of wing deformation shape and the distribution of air flow field are analyzed.The key techniques of morphing drive mechanism,high elastic telescopic skin and coordination control of distributed ultrasonic motors have been researched.The system integration of small variable camber wing has been achieved.The wind tunnel experimental data show that this kind of variable camber wing can realize the drive and control function of adaptive morphing wing in low speed flying condition and improve its lift and drag characteristics.This paper explores a feasible technological approach for applying the piezoelectric precision driving technology to flow control.
