飞机后缘襟翼运动同步性设计和计算

The Design and Calculate For Same Movement Step of Civil Aircraft Trailing Edge Flap

在飞机的起飞、降落、巡航飞行中,襟翼运动起着重要的作用。全机有多块内、外襟翼,当分别绕各自不同的转轴运动时,会产生不同的圆锥运动。为实现所有的内、外襟翼同步运动,需对每块襟翼上的不同作动器进行精心设计、布局,及对作动器运动参数进行计算。这既非常关键,又相当复杂,一直是设计中的难题。介绍了现代客机襟翼作动器运动学计算方法及内、外襟翼同步运动中的误差计算与分析,其计算方法和结果已成功应用在飞机中。

The flap movement makes important effect in phase of Aircraft taking off、landing and cruise. More pairs of inboard、outboard flaps at Aircraft will product different cone movement round different axial movement respectively. Design and arrangement to different actuators of each pair of slap must be used due to ensure every inboard and outboard flaps some movement step and parameter calculates of actuators movement are used. These projects are very key、very complex and every difficult in design.The flap actuator kinematics calculate method of model civil aircraft trailing edge flap are introduced and same movement step error analysis of inboard and outboard flaps is described in this paper. These calculate method and results have succeed applied on Aircrafts.
