The invention relates to a sail propulsion device comprising: a mast (3); inflatable or non-inflatable sail (1) consisting essentially of two substantially sealed adjacent surfaces (5) connected to each other around their periphery so as to form between them at least one closed cavity, said sail comprising an upper portion (6), a lower portion (7), a leading edge (8) and a trailing edge (9), said sail comprising, over the entire length, different arcuate portions forming a projection; the air guide pipe is arranged between the inner part and the outer part of the cavity of the sail; at least one means for injecting air into the cavity, the sail having a profile that remains permanently symmetrical once inflated regardless of the movement of the propulsion means or the direction or strength of the wind; a top plate (10) located at the upper part of the sail; and a sail receptacle (11) located between the leading edge and the trailing edge at the lower part of the sail. The device according to the invention is characterized in that the mast is arranged in front of the aerodynamic thrust center of the sail, the mast can or cannot be freely rotated by 360 degrees, and the sail comprises at least one means for maintaining a slight low pressure in the sail.
本发明涉及一种风帆推进装置,该风帆推进装置包括:桅杆(3);可充气或非充气式风帆(1),其基本上由两个大体密封的相邻表面(5)组成,两个相邻表面(5)围绕它们的周边彼此连接,从而在它们之间形成至少一个闭合腔体,所述风帆包括上部(6)、下部(7)、前缘(8)和后缘(9),所述风帆在整个长度上包括形成凸起的不同弧形部;空气导管,其设置在风帆的腔体的内部和外部之间;至少一个用于将空气注入所述腔体的装置,风帆一旦充气不论所述推进装置的移动或者风的方向或强度如何都具有保持永久性对称的轮廓;顶板(10),其位于风帆的上部;以及风帆容座(11),其在风帆的下部位于前缘与后缘之间。根据本发明的装置的特征在于,桅杆设置在风帆的气动力推力中心的前方,桅杆能够或不能够自由旋转360°,并且风帆包括至少一个保持风帆中轻微低压的装置。
