The invention discloses a surface paddle propeller combined high-speed boat sliding elevation angle control device and a high-speed boat, the high-speed boat is driven by two surface paddles, each surface paddle comprises a stern shaft and a propeller installed on the stern shaft, the stern shafts are sleeved with stern shaft tubes, an elevation angle control device is arranged between the two stern shaft tubes, and the elevation angle control device is located in front of the propellers; the elevation angle control device comprises a hydrofoil located below the stern shaft, and the two ends of the hydrofoil are connected with the two stern shaft pipes through connecting structures respectively. Before the high-speed boat slides, the propellers and the elevation angle control device are located below the free liquid level, in the sliding process of the high-speed boat, the hydrofoils are stressed, so that the high-speed boat is subjected to head lowering torque, the head lowering torque can counteract most head raising torque, and therefore the elevation angle of the high-speed boat is reduced, the visual angle of a driver is increased, and the control safety is high.
本发明公开了一种联合表面桨推进器高速艇起滑仰角控制装置及高速艇,高速艇由两个表面桨驱动,表面桨包括艉轴和安装于艉轴上的螺旋桨,艉轴套设于艉轴管内,两个艉轴管之间设有仰角控制装置,仰角控制装置位于螺旋桨的前方;仰角控制装置包括位于艉轴下方的水翼,水翼两端分别通过连接结构与两个艉轴管连接。高速艇起滑前,螺旋桨和仰角控制装置位于自由液面以下,高速艇的起滑过程中,水翼受力导致高速艇受到低头力矩,该低头力矩可以抵消大部分抬头力矩,从而减小了高速艇的仰角,增大了驾驶员视角,操纵安全性高。
