Title:
LIGHTWEIGHT ROTARY SAIL AND APPLICATION OF SUCH A SAIL
Document Type and Number:
WIPO Patent Application WO/2022/167668
Kind Code:
A1
Abstract:
The invention relates to a Flettner rotary sail (800) capable of turning about a vertical axis, and comprising an aerodynamic surface of rotation extending between a proximal end and a distal end, comprising, between its two ends, a plurality of sections centred on the vertical axis and extending along said axis between two parallel circular hoops, respectively of diameter 2r; and 2r2, the hoops being spaced apart by a distance 2h along the vertical axis, the shape of the aerodynamic surface of the section being defined by the revolution of a continuous meridian curve comprising, between the two hoops, a throat of radius r0 less than or equal to r; and less than or equal to r2.
