摘要
Abstract
The aerodynamic effect of parameters including aspect ratio, spanwise position of the leading edge kink, leading edge sweep of the inboard wing and leading edge sweep of the outboard wing, were studied for outboard dual-swept flying wing configuration. The effects of parameters variation on lift coefficient and lift-to-drag ratio were obtained. The results showed that: Firstly, the changing trend of aerodynamic forces with every parameter presented to be nonlinear. Secondly, the spanwise position of leading edge kink, leading edge sweep of the inboard wing and aspect ratio have relatively remarkable effect on the aerodynamics. Finally, the aerodynamic characteristics could be improved by decreasing the distance from leading edge kink to A/c centerline and leading edge sweep of the inboard wing, or increasing the aspect ratio. Additionally, the result showed that different parameters had an interactively coupling effect on aerodynamic characteristics.关键词
