The invention belongs to the technical field of water surface take-off and landing control of water surface aircrafts, and particularly relates to a water surface take-off and landing longitudinal control method of an amphibious aircraft. According to the method, the corresponding elevator deflection angles when the aircraft slides at the median trim angles at different speeds are determined through test flight, and elevator control rate curves in the takeoff process of the aircraft are drawn through the test flight speed, the median trim angles and the corresponding elevator deflection corresponding relations of the test flight speed, the median trim angles and the corresponding elevator deflection angles during takeoff control. The control rate of the aircraft elevator in the takeoff process of the aircraft on the still water surface and the wave water surface is obtained; during dampening control, after the aircraft receives water, a pilot gradually drives a rod, so that the elevator deflection angle is in the minimum value state in the maximum available rudder deflection angle combination until the aircraft decelerates on the water surface. According to the invention, the unstable influence caused by the interference on the take-off and landing of the amphibious aircraft due to the influence of water surface waves in the take-off and landing processes of the amphibious aircraft is effectively solved, and the take-off and landing safety is improved.

    本发明属于到水面飞行器水面起降操纵技术领域,具体涉及一种水陆两栖飞机水面起降纵向操纵方法。本发明通过试飞,确定飞机在不同速度下以中位纵倾角滑行时对应的升降舵偏角,起飞控制时,利用试飞速度、中位纵倾角及其对应的升降舵偏对应关系,分别绘制飞机在起飞过程中升降舵控制率曲线,得到飞机在静水面、波浪水面起飞过程中飞机升降舵控制率;着水控制时,在飞机接水后,飞行员逐步带杆,使升降舵偏角处于最大可用舵偏角组合中的最小值状态,直到飞机在水面减速完成为止。本发明有效解决水陆两栖飞机在起飞、着水降落过程中,由于水面波浪影响,对飞机起降带来的干扰而造成的不稳定影响,提高起降安全性。
