    摘要: Shape memory alloy-actuated propeller blades and shape memory alloy-actuated propeller assemblies are disclosed. An example propeller blade includes a propeller body (212), a plate (222) coupled to the propeller body (212), a torque transfer member (220), and a shape memory alloy (SMA) actuator (218). The torque transfer member (220) has a distal end attached to the plate (222) such that the torque transfer member (220) applies to the plate (222) at least a portion of a torque applied to the torque transfer member (220) at a proximal end ofthe torque transfer member (220). The SMA actuator (218) has a distal end and a proximal end. The distal end of the SMA actuator (218) is attached to the torque transfer member. (220) The proximal end ofthe SMA actuator (218) is coupled to the propeller body (212) such that the distal end is mated to the propeller body. (212) The SMA actuator (218)is configured to apply the torque to the proximal end of the torque transfer member (220) in response to an application of heat to the SMA actuator (218).
