Understanding Aileron Morphing

Ailerons are te primary roll- control surfaces located on thee trailing edges of wings. In a conventional aircraft, deflecting a rigid ailron upward or downward changes thee fft distribution across the e wing, generating a rolling moment. However, the abrupt geometry change of a hinged surface creats flow separation, drag penalties, and a limited authorityty- to -drag ratio.
