Abstract�� The saucer-shaped aircraft is a novel aircraft adopting blend-wing-body configuration. The linear perturbation theory based on the classic flight dynamics was used to analyze the lateral and directional flight qualities of the saucer-shaped aircraft under low speed conditions, and the time-domain method was applied on the lateral and directional mode. The lateral and directional flight qualities were given by simulation. The aerodynamic characteristics of the saucer-shaped aircraft, the conventional aircraft and the flying wing aircraft were also contrasted to discuss their similarities and differences. The results show that the saucer-shaped aircraft exhibits superior flight qualities and excellent comprehensive performances.
Keywords�� flight dynamics   stability   flight qualities   saucer-shaped aircraft
