G621 Aerodynamics Simulation of a Paper Airplane

This paper presents results of flight simulations of a paper airplane in the dynamic motion, where both fluid dynamics and flight dynamics are considered. The flight of six degree of freedom is calculated by use of Moving Computational Domain (MCD) Method. This numerical method can be applied to simulate the dynamic motion of a paper airplane in the physical space without the restriction of region size. In this paper, as a demonstrative calculation, the flight, such as circling movements, of a paper airplane is simulated. The computed results show the dynamics of flow around a paper airplane during the flight.
