WebJan 24, 2024 · Some high-speed aircraft are equipped with inner ailerons to reduce the torsional deformation of the wings caused by the deflection of the ailerons. Therefore, the internal ailerons are also called high-speed ailerons. In the design process of an aileron, four parameters need to be determined.
