The invention discloses a boat bottom for a high-speed boat. The small high-speed boat glides on the sea surface and is shallow in draught, on one hand, lift force is generated by means of collision between the boat body and seawater, on the other hand, the catamaran is adopted, the lift force is increased by means of the ejection effect of air on the boat body and the sea surface, and meanwhile the resistance between the boat body and the seawater can be greatly reduced through air energy. The ship bottoms on the two sides are simplified into thin steel plates and go deep into the sea surface by a certain distance, so that a strong constraint space is formed between the ship bottoms and the sea surface, the ship bottom in the middle is wide, wavy ground-effect wings are distributed on the ship bottom in the middle and can glide on the sea surface, the ship bottom which is sunken upwards is arranged between the ship bottom and the ship bottom in the middle, an air inlet channel is formed, and wavy ground-effect wings are also distributed on the ship bottom in the middle. During high-speed movement, the whole structure is located above the water surface, only a small part of the structure is located near the water surface, the operation resistance is small, and the wave-shaped ground-effect wings distributed in an array mode are adopted, so that the loading capacity of the ship can be effectively improved.
本发明公开了一种高速艇用船底。小型高速艇在海面滑翔,吃水浅,一方面依靠船身和海水的碰撞产生升力,另一方面采用双体船,利用空气在船身和海面的弹射作用,增加升力,同时空气能大大减小船身和海水之间的阻力,基于以上原理,本发明采用“M”型船底,最两边船底简化成薄型钢板,深入海面以下一定距离,使船底和海面形成强约束空间,最中间船底较宽,分布有波浪式地效翼,可以在海面滑翔,两者之间是向上凹陷的船底,形成进气道,也分布有波浪式地效翼,采用破浪型船头,船头两边是渐变型进气口,和船底进气道相连,本发明在高速运动时,整体结构都处于水面以上,只有很小部分结构处于水面附近,运行阻力小,采用阵列分布的波浪形地效翼,可有效提高船舶荷载能力。
