Wind propulsion thanks to advanced French technology

Wind propulsion thanks to advanced French technology

Research Center for Marine Architecture and Industry (Crane) Technologies from France You have obtained in-principle (AIP) approval from your class society colleague Bureau Veritas (BV) for your accessories wind propulsion for cargo ships,

the concept of The suction wing, also known as the SW270 . is calledthis is a solid rough edgeequipped with a rear flap, jointly developed by Crain and its partner REEL (Rationnel Economique Esthétique Léger). The grilles on either side of the wing section create a suction force that pulls in the air stream From outside the wing section to the inside of the wing. The wing is mounted on a structural base containing the suction fan needed to operate the system.

The suction wing concept is said to provide a very high lift coefficient, reducing the size of the device required to achieve a given pulling force. ,Thanks to the size of the system, drag remains moderate, Therefore, the lift-to-drag ratio provides a Good performance in downwind conditions and for boats sailing at relatively high speedsusing air to propel the ship in conjunction with the main engine,” said B.V.

The wing section can rotate around a vertical axis to adjust wind direction and optimize performance, The device considered in this AIP is a . was Wing with a span of 27 square metersBut BV notes that the concept can be obtained in a variety of sizes to suit different vessel sizes.

« Suction Wing SW270 To Una Innovative wind-assisted propulsion solution suitable for a wide range of cargo vessels, developed using Technologies already widely used by the shipbuilding industryIt provides high strength in proportion to its surface area and is easy to install and use on ships,” said Crane CEO Philippe Pallu de Barrier.

Firm executive said allows cooperation with BV “Proceed to the next step, providing the specification for the industrialization of the SW270 by our partner”,
