For lateral-directional stability analysis, the horizontal tail geometricparameters effect has not been considered. In the present work, the effect ofhorizontal tail aspect ratio on the lateral-directional stability derivatives,rolling static, lateral dynamic stability and Routh discriminate of the airplaneis investigated.The increasing of the horizontal tail aspect ratio improves both the rollingstatic stability and damping ability in the rolling convergence mode anddecreases the damping ability in spiral mode. The results could be used as realdesign requirements for further configuration improvements of the airplane.
