To realize the aircraft maneuvering turn during ground operations, the aircraft's nosewheel control system should provide the rate of nosewheel deflection as higher as possible. To prevent the aircraft's wheel from lateral slip the deflection rate should be limited in a certain range. Take a certain type of aircraft as an example, the effect of lateral slip under the large nosewheel deflection, the friction coefficient on the ground, the aircraft taxiing speed and the rate of nose wheel deflection are analyzed. Results show that the aircraft makes large nosewheel deflection at the rate of 0.3～0.4 rad/s, it can basically meet the ground stability requirements, but to reduce the risk of lateral slip on the low friction pavement, the rate of nosewheel deflection needs to be reduced when the nose wheel deflects to a large angle.%飞机若想尽快实现地面机动转弯, 则前轮转弯操纵系统操纵速率应尽量大, 而为了保证飞机地面机动不会引起前 (主) 机轮侧向滑动, 又要求前轮转弯操纵速率应限制在一定范围内.以某型机为例, 分析大动力操纵角下, 地面摩擦系数、飞机滑行速度及转弯操纵速率对前、主机轮侧滑影响.结果表明:飞机以0.3～0.4 rad/s的平均操纵速率进行大角度转弯, 基本能满足地面稳定性要求, 但为了降低飞机在低摩擦道面上的侧滑风险, 需降低前轮偏转到大角度时的操纵速率.
