Abstract
A tilt-rotor plane represented by V-22 Osprey has an accurate aviation control capability and a high flight capability, because it has advantages of both of a helicopter and an airplane. However, rotation of twin-engine prop-rotors or changing of the modes of the plane will create very complicated flows. To simulate these complicated moving boundary problems, computational method for complicated shapes, movements and deformations is required. Therefore, in this paper, moving computational domain (MCD) method using unstructured grid is constructed. Furthermore, moving grid method for large deformation is applied to the method. And last, as application of present methods, the flight of tilt-rotor plane is simulated.
