The invention discloses a drag reduction double-body unmanned ship. The drag reduction double-body unmanned ship comprises a deck and two sheet bodies, the two sheet bodies are connected with the twosides of the deck correspondingly, and the top faces of the middles of the sheet bodies are flush with the top face of the deck; each sheet body comprises a ship tip located at the front end of the sheet body and a square tail located at the tail end of the sheet body; each ship tip is in an arc shape inclining forwards from back, the width of each ship tip is gradually reduced from back to front,and the top end of each ship tip is higher than the top face of the deck; the top face of each square tail is flush with the deck, and the bottom face of each square tail is in an arc shape extendingfrom bottom to top; and the center distance of the two sheet bodies is K, the width of the sheet bodies is b, and the relative center distance K/b is larger than or equal to 3 and smaller than or equal to 4. Through resistance optimization calculation, the proper relative center distance between the two sheet bodies of the ship body is determined, interference between the sheet bodies is reduced,the strength of the ship body is improved, meanwhile, resistance is reduced, the head of the ship adopts the design of the forward-inclining ship tips, the tail of the ship adopts the design of the square tails, the radian of the ship is increased on the basis of the forward-inclining ship tips, and the parts with concentrated stress are reduced.
本发明公开一种减阻双体无人船,包括甲板和两个片体,所述两个片体分别连接于甲板的两侧,片体中部的顶面与甲板的顶面平齐,片体包括位于片体前端的船首尖和位于片体尾端的方尾,船首尖为由后往前倾的弧形,船首尖的宽度由后往前逐渐减小,船首尖的顶端高于甲板的顶面,方尾的顶面与甲板平齐,方尾的底面呈由下往上延伸的弧形,两个片体的中心距为K,片体的宽度为b,相对中心距为K/b,3≤K/b≤4。通过阻力优化计算,确定船体两个片体之间合适的相对中心距,减少片体之间的干扰,增加船体强度的同时让阻力减少,船首采用前倾型船首尖的设计,船尾采用方尾的设计,船首在前倾型的基础上,增加弧度,减少应力集中减少应力集中的地方。
