内容記述 | Flow field around a configuration of supersonic transport with high-lift devices at low speed and high angle of attack was investigated by solving Reynolds-averaged Navier-Stokes equations. The configuration was consisted of a fuselage and a cranked arrow wing, with leading-edge and trailing-edge flaps. Numerical simulations were conducted and validated at conditions of the wind-tunnel test. Details of flow field at the design condition were analyzed using computational results. Effect of the high-lift devices on aerodynamic performance was discussed. The leading-edge vortices were reduced both in size and in strength by deflecting the leading-edge flap and the drag was reduced. A typical leading-edge vortex flap was confirmed. The trailing-edge flap increased the effective camber of the wing and improved the lift force. Furthermore, it was shown that the aerodynamic performance was improved by combination of the leading-edge and trailing-edge flaps. | |||||
