| Research Abstract |
To obtain engineering design guidelines of main wings or tails toward realization of a Mars airplane that flies in the very rare Martian atmosphere, the relationship between design parameters of a three dimensional wing and aerodynamic characteristics at low Reynolds numbers are clarified and knowledge about fluid dynamic mechanisms which causes aerodynamic changes is obtained. Besides, wind tunnel tests on aerodynamic characteristics of a Mars-airplane scale model are conducted. Effectiveness of control surfaces becomes low at low Reynolds numbers. This is due to nonlinear aerodynamic characteristics of a tail airfoil and the effectiveness of control surfaces is improved successfully by a proper tail airfoil
