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。 In order to carry out research on static ground control torque of front landing gear front wheel, the composition of static ground control torque of front wheel of single-wheel nose landing gear is introduced, the torque characteristics of each part are studied, the mathematical formulas of each torque are emphatically deduced, The relationship between torque and steering angle. The results show that the maneuver torque required to overcome the friction force of the front wheel is the maximum, the maneuvering torque to overcome the rolling friction of the main wheel and the steering torque required to deflect the front wheel are larger when the front wheel is steered at a large angle.
