抄録（英）
Aerodynamic characteristics of delta and rectangular wings under the low-Reynolds-number condition are investigated by CFD and theoretical analysis. For CFD, Farve-averaged Navier-Stokes equations are solved with Baldwin-Lomax model. Present results show that aerodynamic characteristics of delta and rectangular wings are almost the same under the attached flow condition. While, the delta wing have better aerodynamic characteristics at the high angle of attack condition because the lift by leading-edge-separated vortex prevent sudden decrease in lift coefficient which is observed in analysis of rectangular wing. Also, present results show that theoretical estimation does not work well because formed drag has strong influence on the entire aerodynamic characteristics.
