Characteristic Research of Static Steering Ground Torque for Aircraft Single Nose Wheel

为了开展前起落架前轮静态地面操纵力矩研究,介绍单轮前起落架前轮静态地面操纵力矩的组成,对各个分力矩特性进行研究,重点推导各个分力矩的数学计算公式,并计算各操纵力矩与操纵角度的关系。结果表明:克服前轮地面摩擦力所需的操纵力矩最大,克服主轮滚动摩擦力所需的操纵力矩和偏转前轮上举飞机所需的操纵力矩在大角度操纵前轮时较大。

To carry out the research of static steering ground torque for aircraft single nose wheel, composition of static steering torque for aircraft single nose wheel is introduced. Every component torque characteristic is studied. Every component torque formulation is deduced. And relationship between each steering torque and control angle are calculated. The results show that the steering torque against nose wheel ground friction force is the maximum;steering torque against main wheel rolling friction force and steering torque against lifting aircraft are bigger when steering nose wheel with wide angle.
