摘      要：In this paper,the morphing trailing edge is designed to achieve the up and down defection under the aerodynamic *** a detailed and accurate computational analysis to determine the SMA specifcations and layout programs,a solid model is created in CATIA and the structures of the morphing wing trailing edge are produced by CNC machining.A set of DSP measurement and control system is designed to accomplish the controlling experiment of the morphing wing trailing *** last,via the force analysis,the trailing edge is fabricated with four sections of aluminum alloy,and the arrangement scheme of SMA wires is *** of precise control integral has been performed to survey the control *** experiment consists of defection angle tests of the third joint and the integral ***,the ultimate defection angle is tested in these two ***,the controlling experiment of different angles could be performed within this *** results show that the defection error is less than 4%and response time is less than 6.7 s,the precise controlling of the morphing trailing edge is preliminary realized.
