摘　　要：根据一例飞机地面检查中出现的故障,研究了机械操纵分系统和控制增强分系统组成的人工飞行控制系统工作时对驾驶杆行程和驾驶杆力的影响。两个分系统同时工作比仅机械操纵分系统单独工作,驾驶杆行程会缩小,缩小的比例与控制增强分系统的权限相等,但平尾的偏度保持不变,飞机的操纵性不受影响。采用杆力传感器的控制增强分系统工作后,当驾驶杆推拉到缩小后的极限行程附近时,可能会出现抵抗力、回弹力。According to a phenomena in an aircraft ground test, this paper analysed the influences on control- stick movement range by authority of the control augmentation subsystem. The manual flight system consists of the mechanical control subsystem and the control augmentation subsystem. Comparing to the case in which only the mechanical control subsystem worked, when the two subsystems worked, the control-stick movement range decreased, the decrease proportion was equal to the authority of the control augmentation subsystem, but the deflection degree of the horizontal stabilizer was not decrease, the handle quality of aircraft was not influenced. If the control augmentation subsystem used a control-stick force sensor, when the control-pilot stick arriving the limit point of its movement range, perhaps there would be a rejecting force on the control-stick.
