Outline of Final Research Achievements

In this research, "efficient digital flight simulation based on aerodynamic database" has been carried out in view of the time variation of aerodynamic forces. Firstly, the Kriging model aerodynamic database construction was considered. Here, aerodynamics were acquired by the computational fluid dynamics. Looking up this database to solve equations of motion, the efficient flight simulation could be achieved. In 2013, usage of Kriging model was investigated for the prediction of aerodynamics around aircraft. In 2014, Kriging based aerodynamic database was coupled with equations of motion. As this result, the flight mode such as Phugoid could mode be simulated. In addition, for higher efficient aerodynamic database, Proper Orthogonal Decomposition(POD) is used to analyse unsteady aerodynamics and compression of aerodynamic data to construct aerodynamic database efficiently.
