The invention relates to the technical field of rigid sail wings, in particular to rigid double sails capable of weakening vortex shedding influence and a method. The rigid double sail capable of weakening the vortex shedding influence comprises a main sail body and an auxiliary sail body, a slit is formed between the main sail body and the auxiliary sail body, at least one skin is arranged between the tail edge of the main sail body and the front edge of the auxiliary sail body, and multiple sets of holes of different sizes are formed in the skin; the device further comprises an adjusting device and a tensioning device. The adjusting device comprises a first driving device, and the first driving device controls any group of holes of the skin to be located at the slit position; the tensioning device comprises a second driving device, and the second driving device controls the skin to be tensioned. The problems that under the continuous vibration effect caused by vortex shedding, the sail wings and the mast are subjected to fatigue damage and structural instability, and the service life of the sail wings, the working efficiency and the sailboat safety are seriously affected are solved.
本发明涉及刚性帆翼技术领域,特别是一种削弱涡脱落影响的刚性双帆及方法。其中,本发明的削弱涡脱落影响的刚性双帆,包括主帆和从帆,所述主帆和所述从帆之间具有狭缝,所述主帆的尾缘与所述从帆的前缘之间至少设置一个蒙皮,所述蒙皮上设置多组不同尺寸的孔隙;还包括调节装置和张紧装置;所述调节装置包括第一驱动装置,所述第一驱动装置控制所述蒙皮的任意一组所述孔隙处于狭缝位置;所述张紧装置包括第二驱动装置,所述第二驱动装置控制所述蒙皮张紧。本发明解决了在涡脱落造成的持续的振动作用下,帆翼和桅杆会发生疲劳损坏和结构失稳,对帆翼的使用寿命、工作效率和帆船的安全都会带来严重影响等问题。
