摘　　要：形状记忆合金具有形状记忆效应和超弹性两大特性,利用该特性可以使其很好地应用在航空工业领域:制成扭矩管,实现副翼的启动;制成弹簧,用于控制机翼皮瓣的上翘下弯;嵌入旋翼机翼片中,能改善直升机主控制系统大、重、复杂等问题;应用在发动机锯齿喷口上,能降低噪音减少功率损失。Shape memory alloy is a kind of special function material with shape memory effect and superelasticity characteristics.With these two characteristics,it can be used in the aviation industry： it can be made into torque tube to start aileron and into springs to control the airfoil flaps upward and downward,and embedded in the rotor helicopter to improve a large,heavy and complex issues of the main control system.The application of serrated nozzle on the engine can reduce the noise and the power loss.
