Description
本申请涉及船舶技术领域,例如涉及一种舵叶装置和船舶。The present application relates to the technical field of ships, for example, to a rudder blade device and a ship.
船舶在现代的交通运输业中扮演着非常重要的角色。船舶在航行需要转向的时候,首先通过舵机驱动安装在螺旋桨后方的舵叶进行转动,从而使流经舵叶相对的两个外表面的水流的速度发生变化,使舵叶两个侧面的受到的压力产生不同,形成压力差,从而在舵叶上产生升力,在该升力的作用下船舶发生转向。Ships play a very important role in the modern transportation industry. When the ship needs to turn when sailing, the rudder blade installed behind the propeller is first driven by the steering gear to rotate, so that the speed of the water flowing through the two opposite outer surfaces of the rudder blade changes, so that the two sides of the rudder blade are affected Different pressures are generated to form a pressure difference, thereby generating lift on the rudder blades, and under the action of the lift, the ship turns.
相关技术中的船舶的舵叶,包括常规舵、襟翼舵等均安装在螺旋桨的正后方。由于舵叶本身存在一定的厚度,导致船舶航行时,在舵叶上会产生一定的阻力。为了减少阻力,舵叶的厚度应尽可能减小。但是由于舵叶本身需要具有一定的刚度和强度,故舵叶的厚度不可能无限制的减少,这样也就导致在舵叶上产生的阻力无法减少,由于作用在舵叶上的阻力会影响船舶的航行速度,从而造成燃料大量消耗。Rudder blades of ships in the related art, including conventional rudders and flap rudders, are installed directly behind the propeller. Due to the certain thickness of the rudder blade itself, a certain resistance will be generated on the rudder blade when the ship is sailing. In order to reduce drag, the thickness of the rudder blade should be reduced as much as possible. However, since the rudder blade itself needs to have a certain rigidity and strength, the thickness of the rudder blade cannot be reduced without limit, so that the resistance generated on the rudder blade cannot be reduced, because the resistance acting on the rudder blade will affect the sailing speed, resulting in a large amount of fuel consumption.
