Introduction
The project focuses on the conception, preliminary analysis, and detailed design of a wingsail system intended for auxiliary propulsion of commercial cargo vessels. The work will encompass a telescopic or rigid‑wing concept, definition of indicative laminate lay‑up schedules, structural sizing, and performance estimation. Where feasible, a more detailed design and sizing methodology will be pursued.
What You’ll Work On
Conceptual Design
- Generate two alternative wing‑planform concepts (fully rigid cantilever wing, telescopic wing with internal struts).
- Perform a quick‑hand aerodynamic estimation or study literature to determine a suitable size. Conduct a trade‑off study of structural material families (carbon‑fiber/epoxy, glass‑fiber/epoxy, hybrid composites) and select a baseline material based on density, stiffness, and corrosion resistance.
Indicative Laminate Plans
- Define representative laminate stacking sequences for the primary load‑bearing skins of the wing (e.g., [0/±45/90]s, [90/0/±45]s) and for secondary members (spars, ribs, struts).
- Calculate lay‑up thicknesses required to meet bending, torsion, and buckling criteria using classical laminate theory; present results.
- Estimate overall mass of the wing.
Pre‑liminary Structural Analysis
- Build simplified 3‑D FE models of the selected concept to verify that the chosen laminate schedules satisfy ultimate and serviceability limit states under design wind loads (e.g., 0.8 × dynamic pressure at 20 kn).
- Perform a modal analysis to identify natural frequencies and ensure they do not coincide with expected operational excitation ranges.
Detailed Design (if time permits)
- Refine the geometry of telescopic hinges or locking mechanisms, including tolerance analysis for deployment and stowage cycles.
- Develop detailed connection details between the wingsail and the vessel’s deck‑mounting system, incorporating fatigue‑life considerations for repeated cycles.
- Produce a finite‑element model of the full wing‑structure‑mounting assembly, applying realistic boundary conditions (fixed deck, elastic deck‑flexibility) and run a static load case representing maximum wind pressure combined with ship motion loads.
Reporting
- Compile all design calculations, laminate tables, FE model setups, and performance predictions into a structured technical report. Present the conceptual trade‑off, selected baseline concept, and detailed design outputs to the engineering team for further development
