The invention relates to the technical field of boat drag reduction, and discloses a novel unmanned boat composite drag reduction mechanism which comprises a boat body, a sliding surface is arranged at the bottom end of the boat body, a streamline sliding plate is arranged on one side of the middle of the bottom end of the sliding surface, and groove seats are obliquely arranged on the two sides of the middle of the bottom end of the streamline sliding plate. Two stepped seats are arranged on the other side of the middle of the bottom end of the sliding surface at equal intervals, inclined planes are arranged on the sides, close to the streamline sliding plate, of the two stepped seats, stepped outer grooves are formed in the positions, close to the boat tail, of the bottom ends of the two stepped seats, and supporting floating seats are arranged on the positions, close to the edge, of the other side of the middle of the bottom end of the sliding surface. Ram air is fully utilized to reduce resistance and support the boat weight, so that the sailing speed is greatly increased when the unmanned boat sails, power generated by power potential energy is fully used for propelling the boat body, and the utilization rate of the power potential energy generated in the sailing process of the boat body is remarkably increased.

    本发明涉及艇类减阻技术领域,公开了一种新型无人艇复合减阻机构,包括艇体,所述艇体的底端设置有滑行面,所述滑行面的底端中部一侧设置有流线型滑板,所述流线型滑板的底端中部两侧均倾斜设置有槽座,所述滑行面的底端中部另一侧等距设置有两个断级座,两个所述断级座靠近流线型滑板的一侧设置有斜面,两个所述断级座底端靠近艇尾的位置处均设置有断级外槽所述滑行面的底端中部另一侧靠近边缘处均设置有支撑漂浮座。通过充分利用冲压空气进行减阻和支撑艇重,使得无人艇航行的时候航行速度有了大幅提升,并充分将动力势能产生的动力用于艇体的推进,使得艇体在航行过程中产生的动力势能利用率显著提高。
