大型水陆两栖飞机抗浪能力研究

阐述了大型灭火/水上救援水陆两栖飞机高抗浪船体设计方法，对飞机起飞过程中的水阻力、滑行稳定性和波浪运动响应进行了研究。通过对比分析，发现断阶喷溅形态是影响水阻力出现第2峰值的关键因素，提出了水阻力曲线出现第2峰值的条件；分析了在纵倾角-速度图中不同区域滑行时飞机纵倾角响应特性，明确了飞机在典型状态的稳定边界；通过研究波长、速度对飞机纵倾角、飞高和机身垂向过载的影响，确定了飞机在波浪水面发生剧烈运动响应时对应的波长范围。

Seakeeping performance research of large amphibious aircraft

The design method of the hull of the huge amphibious seaplane for fire extinguishing and rescue is illustrated firstly, then the aircraft's water resistance, planning stability and motion response to rough water are investigated. The results show that the spray configuration is the main factor that affects the second hydro-resistance hump, and the precondition for the second hump is put forward. The characteristic of the trim response to different zones in the trim-speed figure is analyzed, and the stable boundary is also confirmed. By analyzing the effect of the wave length and the speed on the trim, heaving and vertical overload, the range of wave length corresponding to the strenuous exercise response of the plane on wave is confirmed.
