摘　　要：本文基于低速风洞纵向测力以及涡格法的理论计算结果，初步研究了联接翼布局的低速纵向气动特性，并与相应的机翼、尾翼相分离的正常布局的试验结果作了比较。结果表明，联接翼布局具有许多优点，如较大的升力线斜率较大的最大升力系数Ｃｙｍａｘ、较大的纵向稳定度、相当小的诱导阻力Ｃｘｉ和较高的巡航升阻比Ｋ，以及具有直接升力和直接侧力控制的可能性。This paper conducts an investigation into the low-speed longitudinal aerodynamic characteristics of the joined wing configuration on the basis of the results of the longitudinal forces measured testing in lowspeed wing tunnel, and the theoretical calculation of the vortex-lattice method. Comparing with the testing results of the relative conventional wing-tail configuration, the joined wing configuration has many advantages, it has. For example, higher lift curve slope , maximum lift coefficient Cymax and longitudinal stability, higher lift-drag ratio K, relatively lower induced drag Cxi, and possibility of the direct lift and the direct side force controls.The paper also approaches into the possibility which should further increase and improve the longitudinal aerodynamic characteristics of the joined wing configuration when the canard is set forward.
