The invention discloses a self-adaptive ship empennage which is an underwater controllable energy-saving anti-rolling appendage device arranged at the tail of a ship on the water surface. Through self-adaptive adjustment of parameters such as the underwater space position and the attack angle of the empennage, resistance reduction, efficiency improvement, energy conservation and acceleration can be realized in a wide navigational speed range; an advanced algorithm can be combined to control hydrofoil movement to actively control ship body movement, and ship seaworthiness is improved; meanwhile, the tail flow field and the cavitation performance of the propeller disc can be improved to a certain extent, the propeller operation environment is improved, and the propelling efficiency is improved; movement of marine organism fins can be simulated, and ship micro-speed movement is achieved. According to different operation scenes of the water surface ship, self-adaptive adjustment can be achieved, and the aim of improving rapidity and seaworthiness of the ship is achieved. Aiming at different navigational speeds, the empennage is automatically adjusted to the optimal position and attack angle at the navigational speed, and drag reduction and energy saving in a wide Fourier number range are achieved; the empennage position and the attack angle are adjusted in real time, and hull movement in waves is actively and efficiently controlled; and when needing to be folded, the device can be upwards stored close to the tail sealing plate.

    本发明公开了一种自适应船舶尾翼,是一种置于水面船舶尾部的水下可控节能减摇附体装置。通过自适应调整尾翼水下空间位置、攻角等参数,可在宽航速范围内减阻增效,节能提速;亦可结合先进算法控制水翼运动来主动控制船体运动,改善船舶适航性;同时可一定程度改善尾部流场和桨盘空泡性能,改善螺旋桨作业环境,提高推进效率;可模仿海洋生物鳍的运动,实现船舶微速运动。本发明可根据水面船舶不同作业场景,自适应调节,达到提高船舶快速性、适航性的目标。本发明针对不同航速,自动调整尾翼至该航速下的最优位置和攻角,实现宽傅氏数范围内的减阻节能;实时调节尾翼位置和攻角,主动高效控制波浪中的船体运动;可在需要收起时向上靠尾封板收纳。
