Abstract

Abstract: When we design the 3D wing of an airplane, a cruise-shape wing will be designed first, which has the most ideal aerodynamic pressure distribution. In the real flight the wing will be deformed by the aeroelasitcity, which changes the pressure distribution. The twist angle will be optimized to redistribute the pressure on the deformed wing along the spanwise, and thus the pressure distribution can be similar to the ideal cruise shape. A loose coupling method is developed to optimize the twist angle of the jig shape wing, which can be divided into two phase and is able to lower the time and computation resource compared to the tight coupling effectively.
