平尾尾容系数对飞机俯仰敏捷性的影响

研究了平尾容系数对飞机俯仰敏捷性尺度的影响，这些尺度包括加载／卸载时间，最大正／负过载变化率，最大上仰／下俯机运范围内的俯角速率，对比计算表明:较大的尾容系数可获得较高的俯仰敏捷性，而在同一容系数下，较大的平尾面积可比较大的平尾力臂获得更高的俯仰敏捷性。另外，平尾面积和平尾力臂的影响只有一定范围内最显著，故在设计时需进行综合考虑。

Effects of Horizontal Tail Volume Coefficient on Aircraft Pitch Agility

In this paper, effects of horizontal tail volume coefficient on the pitch agility metrics are discussed through comparison computations. These metrics include plus and minus load factor time and rates, pitch rates during maximum pitch up and pitch down maneuvers. The results turn out that the larger the horizontal tail volume coefficient, the higher pitch agility will be, and at the same horizontal tail volume coefficient the larger the horizontal tail area , the higher pitch agility will be, compared with the larger of the horizontal tail moment arm. What's more, as the effects of horizontal tail area and moment arm are more efficient in a certain region, the horizontal tail design should be optimized.
