AI Technical Summary
Technical Problem
Existing methods for manufacturing rotor sail bodies are costly and inefficient, requiring expensive materials like foam cores and resulting in non-uniform inner surfaces that increase resistance and power consumption.
Method used
A method involving laying a first fabric with longitudinal fibers and additional strips of fibers oriented along the sail body axis, followed by resin infusion and curing, to create a sail body with both axial and circumferential strength at a lower cost.
Benefits of technology
The method enables the production of sail bodies with optimal strength and reduced material costs, minimizing weight and power consumption while maintaining structural integrity.

Abstract
A method of manufacturing a sail body (3) for forming part of a wind power assisted propulsion device (4) includes laying a first fabric (14) formed from a first fiber on a mold (16) defining the shape of a part (2) of the sail body (3), and laying a plurality of strips (22) formed from a second fiber on the surface of the first fabric (14) such that at least a part of the second fiber extends longitudinally along the sail body (3).
