The invention provides a seaplane bottom structure, and belongs to the technical field of aircraft body structure design, the structure is characterized in that a break step 2 is located in the middle of a hull 1, a wave suppression plate 3 is located in the outer side area of a wave suppression groove 4, a keel beam 5 is arranged at the bottom symmetry center of the hull 1 and penetrates through the whole hull 1, and a water rudder 6 is located at the tail symmetry center of the hull 1; a plurality of watertight bulkheads 7 are arranged on the hull 1 from front to back in the length direction, and a plurality of common frames 8 are arranged between the adjacent watertight bulkheads 7 on the hull 1 in the length direction; and the front undercarriage cabin 9 is arranged at the symmetrical center of the front part of the hull 1. When the seaplane is used as a fire-extinguishing airplane, a water tank is arranged in the ship bottom space. The layout design method is typical in layout, high in expansibility, high in structure utilization rate, higher in water load impact resistance and suitable for layout design of seaplane ship bottom structures of various sizes.
本申请提供一种水上飞机船底结构,属于飞机机身结构设计技术领域,该结构中断阶2位于船身1中部,抑波板3位于抑波槽4外侧区域,龙骨梁5布置于船身1底部对称中心并贯穿整个船身1,水舵6位于船身1尾部对称中心处,船身1沿长度方向从前至后布置有若干个水密隔框7,同时在船身1沿长度方向相邻水密隔框7之间布置有若干普通框8;前起落架舱9布置于船身1前部对称中心处。当水上飞机作为灭火飞机时,还利用船底空间设置水箱。本申请布局典型,拓展性强,结构利用率高,抗水载荷冲击力更强,适用于各类尺寸水上飞机船底结构布局设计。
