| Abstract | ||
| For lateral-directional stability analysis, the horizontal tail geometric parameters effect has not been considered. In the present work, the effect of horizontal tail aspect ratio on the lateral-directional stability derivatives, rolling static, lateral dynamic stability and Routh discriminate of the airplane is investigated. The increasing of the horizontal tail aspect ratio improves both the rolling static stability and damping ability in the rolling convergence mode and decreases the damping ability in spiral mode. The results could be used as real design requirements for further configuration improvements of the airplane. | ||
