AI Technical Summary
Technical Problem
The sail material of the existing rotor sail is prone to fatigue failure due to stress fluctuations during use in high revolutions, and the manufacturing cost is high.
Method used
Using a laminated structure consisting of a first fabric formed of the first fiber and a plurality of strips formed of the second fiber, the sail body is formed by resin curing, and the fiber layout is optimized to match the bending moment characteristics of the sail body.
Benefits of technology
It achieves the axial and circumferential strength required for the sail body while reducing material costs, extending the service life of the sail body and reducing resistance during rotation.
