Outline of Final Research Achievements

Developments and realization of new concept, "Numerical Airplane", which is a coupled simulation technology of fluid and flight dynamics on computers, have been conducted in this study. Based on the new approach, "Moving Computational Domain Method", the fluid dynamics equation and flight dynamics equation of 6 degree have been solved simultaneously in a coupled manner. Prototypes of “Numerical Airplane”, “Numerical Vehicle”, “Numerical Helicopter”, and so on were demonstrated. Flight simulation of a propeller thrust small airplane of "Mustang" type has been conducted for various acrobatic flight conditions with success. The possibility of "Numerical Real Flight Test" on a computer has been demonstrated. The present approach has also been applied to prediction of motions of "boomerang" and "soccer ball". The trajectories and flow mechanism around the bodies were analyzed and compared with experimental data successfully.
