The invention relates to a wind propulsion unit comprising a double-wing sail mounted on a structure that is angularly controlled about a substantially vertical axis according to conditions, the double-wing sail comprising a front wing (100), a rear wing (200) and a support structure (300), the unit comprises a support structure allowing the front and rear vanes to pivot about two axes substantially parallel and spaced apart from each other, the unit further comprising means for controlling the orientation of the rear vane during propulsion according to the direction of incidence of the wind. According to the invention, the device for controlling the orientation of the rear vane is further configured to bring the rear vane (200) into a folded orientation in which a substantial portion of the cross-sectional area of the rear vane is positioned along a substantial portion of the cross-sectional area of the front vane (100) when the wind propulsion unit is in the inactive position.

    本发明涉及一种风力推进单元,该风力推进单元包括安装在结构上的双翼帆,该结构根据条件围绕大致竖直的轴线进行角度控制,该双翼帆包括前翼片(100)、后翼片(200)和支撑结构(300),该支撑结构允许该前翼片和该后翼片围绕大致平行并彼此间隔开的两个轴线枢转,该单元还包括用于在推进期间根据风的入射方向控制该后翼片的取向的装置。根据本发明,用于控制该后翼片的该取向的该装置还被构造成当该风力推进单元处于非活动位置时使该后翼片(200)进入折叠取向,在该折叠取向中,该后翼片的横截面范围的相当大部分沿着该前翼片(100)的横截面范围的相当大部分定位。
