Adaptive airfoil control for UAVs using smart materials
Deformation of the wing panel when the shape memory alloy (SMA) wires are fully actuated.
Aerodynamic performance is an essential consideration in unmanned aerial vehicle (UAV) design. It is necessary that UAVs cruise close to the best lift-to-drag ratio (L/D), which means flying at a constant angle of attack.
Finding a balance between weight, altitude, speed, and/or wing area is crucial because a failure to do so may cause the L/D to be lower than optimum and the range will be correspondingly less. A variable camber wing may provide a solution.
