Low speed characteristics of the saucer-shaped aircraft

  • Received Date: 14 Jan 2009
  • Publish Date: 28 Feb 2010
  • 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.
