民用飞机后缘襟翼机构设计仿真计算研究

研究了民用飞机后缘襟翼运动机构,并对几种常见的机构形式进行了对比分析。重点研究连杆滑轨机构,它具有驱动力矩小和襟翼扭转力矩小的特点,并且在飞机起飞时襟翼偏角小,同时有较大的富勒运动。根据连杆滑轨机构的特点和机构学理论,建立数学仿真计算模型,并用C++编写了计算仿真软件。文中针对某飞机后缘襟翼参数,通过计算仿真软件计算出襟翼偏角与富勒运动量、缝隙之间的关系以及驱动角与襟翼偏角、富勒运动量、缝隙之间的关系,取得良好结果,证明了该方法的可行性。

Mechanical Design and Research of Trailing Edge Flap for Civil Aircraft

TThis paper describ the civil aircraft high lift devices of trailing edge flap mechanisms,and comparison of several common forms of mechanism.The motion of link/track mechanism is very favorable for Fowler motion at lower takeoff flap angles and requires very low actuation power.The link/track flap mechanism has the low overturning moment from the flap loads.The mathematical model,is,establish based on the link/track flap mechanism and theory of the mechanism.The simulation software is programmed by C++.The...
