Applications of sail propulsion for a 25.000 tdw Bulk-carrier are examined. A program of calculations is developed to ascertain the performances of a system of sails at different wind forces and different angles of attack. Performances are studied assuming as sail profiles either a curved plate or NACA symmetrical profiles. Applications of fabric sails are examined.

Abstract
Applications of sail propulsion for a 25.000 tdw Bulk-carrier are examined. A program of calculations is developed to ascertain the performances of a system of sails at different wind forces and different angles of attack. Performances are studied assuming as sail profiles either a curved plate or NACA symmetrical profiles. Applications of fabric sails are examined. The possibility to elimate the leeway is also investigated, by use of trimming keels. Finally a typical voyage has been assumed and performances of many sail plans are calculated and compared. © 1985.File in questo prodotto:
