Development of a rigid folding sail concept to power large ship in order to decarbonate the maritime fret industry.
A collaborative R&D project with participation of the European Union via the FEDER fund.
Partners: Multiplast, Chantier de l’atlantique, ENSTA Bretagne, GSea Design
Sails designed from 300m² up to 1200m²
Build and test of a small scale sail of 50m²
Definition of the design specifications in collaboration with Chantier de l’atlantique
Performance analysis of the sail using fluid structure interaction to asses the shape and twist control in given sailing conditions.
Definition of the structural scantlings to meet the stiffness, strength and buckling requirements on all parts of the sail.
3D modeling of the sail and components, cinematic analysis during hoist and haul down.
Full set of construction drawings and weight estimate
Guidance during construction and testing
Internal software : OPHELIA
3D modeling: CATIA – 3D experience
Computational fluid dynamics (CFD): Fluent
Composite FEA shell model: NASTRAN
Development of a fluid structure interaction loop between the CFD and FEA models
Drawings: AutoCAD
Our mission : Creating composite parts, which will make a difference tomorrow, both in the marine environment and in industry. Making calculations to ensure our clients the design and fabrication of reliable and innovative composite structures, which perfectly adhere to their needs or ideas, whether they comprise offshore race boats, cruisers or industrial projects.
