所谓静稳定度是指气动中心到飞机重心的距离,气动中心在重心之后静稳定度为正,飞机是静稳定的;气动中心在重心之前静稳定度为负,飞机是静不稳定的。在亚音速飞行状态,普通飞机的翼身组合体的升力中心在重心稍后的某个距离(静稳定),这时翼身组合体的升力所产生的负俯仰力矩(机头向下的力矩),由平尾的下偏,以产生向下的升力来平衡,尾翼的升力从 The so-called static stability refers to the distance from the center of gravity of the aircraft to the center of gravity of the aircraft. The static stability of the center is positive after the center of gravity and the aircraft is stationary. The static stability of the center of gravity before the center of gravity is negative and the aircraft is unstable. At subsonic speeds, the lift center of the wing-body assembly of an ordinary aircraft is some distance behind the center of gravity (static stability) and the negative pitch moment (nose-down moment) produced by the lift of the wing-body assembly ), By the lower end of the flat tail, to produce a downward lift to balance the lift of the tail from
