Rigid Wing Sails - Epoxyworks
WebThe wing sail has the main structure and the surface of the leading edge moulded in an aramid epoxy and foam sandwich. Similar construction is used for the hulls. The rest of the wing surfaces are reinforced flexible film stretched on composite battens. Spars, crossbeams, rudders and dagger boards are carbon fibre and epoxy. A wingsail, twin-skin sail or double skin sail is a variable-camber aerodynamic structure that is fitted to a marine vessel in place of conventional sails. Wingsails are analogous to airplane wings, except that they are designed to provide lift on either side to accommodate being on either tack. Whereas wings adjust … See more Wingsails are of two basic constructions that create an airfoil, "soft" and "hard", both mounted on an unstayed rotating mast. Whereas hard wingsails are rigid structures that are stowed only upon removal from the … See more The presence of rigging, supporting the mast of a conventional fore-and-aft rig limits sail geometry to shapes that are less efficient than the narrow chord of the wingsail. However, conventional sails are simple to adjust for windspeed by reefing. Wingsails typically … See more Wingsails change camber (the asymmetry between the top and the bottom surfaces of the aerofoil), depending on tack and wind speed. A wingsail becomes more efficient with … See more • Media related to Wings (sailing) at Wikimedia Commons See more et toi in french
