Calculation of hydrodynamic & aerodynamic performances of ACCWING patented wingsail concept.

Within the context of the collaboration between SIREHNA & ACCWING, a series of calculation of both hydrodynamic & aerodynamic have been performed in order to estimate the performance of the concept on a 65m clipper equipped with 4 masts of 35m and a total of 900m2 of sails.

ACCWing is a patented wingsail concept led by French inventor Hugues de Turckheim and Philippe Marcovich. The new company is lodged into Sicomin Holding, with the goal to promote the worldwide manufacturing of masts and wingsails for sailboats or merchant ships of many types.
The carbon fibre masts supporting the wings are manufactured by epoxy infusion or prepreg.Both stayed and unstayed masts are non rotating and of elliptical shape, without spreaders.
