摘　　要：为了获得盒式布局飞机的飞行品质特征,对新型亚声速盒式布局飞机的气动特性进行了计算,采用时域分析的方法对其纵向模态进行了分析,并与常规飞机的特性进行了比较,提出了改善盒式布局飞机飞行品质的有效措施。研究结果表明,盒式布局飞机具有良好的升阻特性和特殊的纵向操稳特性。Aerodynamic computation is conducted to analyze the characteristics of subsonic aircraft with joined-wing configuration, and the time domain analysis is applied on longitudinal modes ,and compared its property with common aircraft, the effective measure which can improve the flight qualities of aircraft with joined-wing configuration as well. The result shows that the joined-wing aircraft has high lift-drag ratio and specific stability and controllability.
