The invention discloses a supercharged sail, and relates to the technical field of wind propulsion. The device comprises a fixed base, a main sail cylinder, a slewing bearing, a main sail slewing driving mechanism, a supporting structure, a lower guide plate, a front edge structure, a rear flap, a flap slewing driving mechanism, a flap lower connecting rod, a flap upper connecting rod, an upper guide plate and a fan. A cylindrical design is adopted as an airflow channel, the compactness of the rotary cylinder sail and the aerodynamic characteristics of the hard wing sail are combined, meanwhile, the production and manufacturing difficulty is lower, and meanwhile, the main sail cylinder body is compact in structure, small in occupied deck space and suitable for being installed on various ship types; the design of a hard wing sail is used for reference, windward is carried out at a specific attack angle, airflow flowing is optimized, and lift efficiency is improved; air is sucked into the main sail cylinder through the fan and discharged, front-back pressure difference is formed, and thrust is enhanced. By means of the design, dependence on natural wind speed is remarkably reduced, operation at a lower wind speed (such as the third level of Typha wind level or below) can be achieved, and the application scene is expanded.
本发明公开一种增压式风帆,涉及风力推进技术领域;而本发明包括固定底座、主帆筒体,回转支承、主帆回转驱动机构、支撑结构、下导流板、前缘结构、后襟翼、襟翼回转驱动机构、襟翼下连接杆、襟翼上连接杆、上导流板和风机;通过采用圆柱形设计作为气流通道,结合旋筒风帆的紧凑性和硬质翼帆的空气动力学特性,同时生产制造难度更低,同时,主帆筒体结构紧凑,占用甲板空间小,适合多种船型安装;通过借鉴硬质翼帆的设计,以特定攻角迎风,优化气流流动,提升升力效率;通过风机将空气吸入主帆筒体内部并排出,形成前后压差,增强推力。这一设计显著降低了对自然风速的依赖,可在更低风速下运行(如蒲氏风级三级以下),扩大了适用场景。
