摘要：
This paper examines, analytically and experimentally, a shape memory alloy (SMA) wire actuator to be used for in-flight tracking of helicopter rotor blades. The recovery characteristics of SMA's are utilized to deflect a trailing edge trim tab. Conceptually, the tab is deflected using SMA wires with initial pre-strains, and any differential recovery displacement due to a thermal field is transformed into an angular motion of the tab. A one-dimensional thermo-mechanical constitutive model is used to predict the constrained recovery characteristics of SMA's and predicted results are validated with measured values. Good correlation between measured and predicted values is obtained.
