The invention discloses an anti-pitching channel propeller, which is arranged on a ship body appendage, a certain distance is formed between the anti-pitching channel propeller and the gravity center of a ship body, the anti-pitching channel propeller comprises a channel and a propeller body, and the channel is formed in the ship body appendage; the propeller is arranged in the channel, and the propeller is rotatably connected with the ship body appendage; the propeller is connected with a driver, and the propeller rotates to generate torque for resisting pitching motion of the ship body. The anti-pitching channel propeller is arranged on a rudder or other ship body appendages, a certain distance is formed between the anti-pitching channel propeller and the gravity center of a ship body, the anti-pitching channel propeller comprises a channel and a propeller body arranged in the channel, and the propeller body can generate torque for resisting pitching motion of the ship body when rotating, therefore, the effect of slowing down the violent pitching motion of the ship in the waves is achieved. The anti-pitching channel propeller can be arranged at the position far away from the gravity center position of a ship body.
本发明公开一种减纵摇槽道螺旋桨,设置于船体附体上,减纵摇槽道螺旋桨与船体重心之间具有一定距离,减纵摇槽道螺旋桨包括槽道和螺旋桨,槽道开设于船体附体上;螺旋桨设置于槽道内,螺旋桨可转动地与船体附体相连;螺旋桨连接有驱动器,螺旋桨转动能够产生抵抗船体纵摇运动的力矩。本发明的减纵摇槽道螺旋桨,设置于舵或其它船体附体上且与船体重心之间具有一定距离,减纵摇槽道螺旋桨包括槽道和设置于槽道内的螺旋桨,螺旋桨转动时能够产生抵抗船体纵摇运动的力矩,从而达到减缓舰船在波浪中剧烈纵摇运动的效果。本发明的减纵摇槽道螺旋桨,可以设置在距离船体重心位置较远的位置。
