摘要: 碟形飞行器是一种新颖的,采用翼身融合布局的飞行器.为获得碟形飞行器在低速条件下的总体特性,对其进行了风洞测力和动导数测量试验,结合稳定性分析和模型试飞研究了其总体性能.研究结果表明:碟形飞行器最大升阻比为12.2,失速迎角28°,全机纵向 模态稳定,横航向滚转模态和荷兰滚模态稳定,螺旋模态发散,具有良好的飞行品质和综合性能.

Abstract: The saucer-shaped aircraft is a novel aircraft adopting blend-wing-body configuration. The wind tunnel experiments, stability analysis and flying tests were conducted to investigate the aerodynamic characteristics and stability features of the saucer-shaped aircraft under low speed conditions. The results show that the highest lift to drag ratio is 12.2, the stall angle of attack is 28°. Meanwhile saucer-shaped aircraft has stable longitudinal mode, rollover mode and Dutch roll mode. The spiral mode is unstable. The saucer-shaped aircraft exhibits superior flight qualities and excellent comprehensive performances.
