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.
