平尾偏转对飞机着陆滑跑性能的影响

为了考察平尾偏转角度对飞机着陆滑跑性能的影响，通过计算流体力学进行气动数据储备，利用多体动力学建模方法，建立了能够反映飞机气动特性随迎角和平尾偏角变化而变化的飞机着陆滑跑动力学模型，在不同的飞机平尾偏转工况下进行了着陆滑跑仿真计算。经过验证，该动力学模型能够较好地反映飞机着陆滑跑时不同平尾偏转角度下动力学特性，仿真结果表明平尾前缘下偏（拉杆）能够有效缩短着陆滑跑距离。

A Study of the Influence of Tail Deflection on Landing Skid Performance of Aircraft

In order to investigate the influence of flat tail deflection Angle on the plane''s landing and taxiing performance, through aerodynamic data by using the method of computational fluid dynamics reserves and by using the multi body dynamics modeling method, this paper builds up a model able to reflect the aircraft aerodynamic characteristics changes over tail peace at an Angle of attack Angle of aircraft landing run dynamics under condition of different plane landed flat tail deflection for taxiing simulation calculation. The results show that the dynamic model can well reflect the dynamic characteristics of aircraft at different horizontal tail deflection angles during landing and taxiing, and the horizontal tail leading edge downward deflection (pull rod) can effectively shorten the landing and taxiing distance.
