The variable-span and cambered span morphing wing for unmanned aerial vehicle (UAV) can greatly improve its flight efficiency. In this work, a new extendable and bendable morphing wing with double driving is designed. The morphing skeleton of wing is composed of the basic unit module which is seven-bar mechanism in series. The rubber-filled corrugated sandwich corrugated skin is designed according to the requirement of morphing skeleton. The kinematics model of morphing skeleton that is composed of three modules in series is established, then the kinematics analysis of morphing skeleton is carried out, at last the expressions of the deformed position and driving angle are obtained. In the case of the same wing span, the influence of different rod length ratio on the maximum extension length of the morphing wing is analyzed, and the influence of different driving speed on the maximum bending angle under the same rod length ratio is compared and analyzed.
