Wing sail technology
Wing Sail Technology : A wingsail is a form of marine propulsion similar to conventional sails. However, a wingsail is a built-up structure with airfoil cross-section, like an airplane wing, which shape can provide a much better lift-to-drag ratio than conventional sails.

L-Shaped Foils on Oracle #AC45: A new innovation after wing extension?

L-Shaped Foils on Oracle #AC45: A new innovation after wing extension? | Wing sail technology | Scoop.it

A forum entry from Pressure-Drop with a collection of pictures taken during Oracle Racing training on President's day. A reader a the Foilers blog (foils.wordpress.com) observed that one of the AC45 was equipped with L-Shaped foils.

Is it a new innovation that will come on the AC45 after the WingSail extension?

Dynamic Fluid Design: Rigid WingSail CFD

Dynamic Fluid Design: Rigid WingSail CFD | Wing sail technology | Scoop.it

The decision to use rigid wing sails for the next generation of America's Cup boats has lead to a race in understanding of this novel sail boat system. The AC45 and AC72 will be fast, light and exciting, and offer a unique challenge to both the sailors and the designers.
While experience with wing sails has been gained in the smaller c-class wing sail boats, Computational Fluid Dynamical modelling of wing sails can aid in the understanding of the complex interaction between the multi-element rigid wing sails and the conventional flexible foresail.

By now you’ve all seen plenty of photos of the AC45 wingsails in action, but do you know how they’re built? Peter Nielsen paid a visit to the manufacturers, Core Builders Composites, in Warkworth, New Zealand, to find what goes into one of these featherweight rigs.

Winging It: America’s Cup Racers Push the Sailboat to Its Limits

Winging It: America’s Cup Racers Push the Sailboat to Its Limits | Wing sail technology | Scoop.it

John Kostecki has one instruction for me: “Hold on.” It’s a sunny day in New Zealand’s Hauraki Gulf, off the coast of Auckland, and I’ve just boarded Kostecki’s boat. Actually, calling it a boat suggests something a lot more substantial than what I’m standing on. It’s the barest skeleton of a raft, a wisp of a catamaran 22 feet wide by just under 45 feet long. Called an AC45, it’s a bantam version of the next-generation America’s Cup yacht, and it’s unlike anything else on water. Above me is not a sail but a solid wing, mounted vertically like a fin. At 70 feet tall, it is longer than the wing of a Boeing 727. Yet the craft that this massive airfoil propels is almost fully dematerialized—a CAD file in wireframe hovering over the bay. As far as I can tell, there’s nothing to hold on to.

Video: Anatomie de l'AC 45 "un petit précurseur prometteur" by @Voiles_Voiliers | Wing sail technology | Scoop.it

Lancé en janvier 2011, l’AC 45 préfigure ce qui sera le support de la 34ème Coupe de l’America. Il s’agit d’un catamaran à aile rigide de 45 pieds monotype qui permettra aux concurrents de s’entraîner en attendant l’arrivée des AC 72, support officiel de la Cup en 2013. Révolutionnaire tout en restant accessible aux équipages habitués des Class America, les premiers bords de l’AC 45 ne sont pas passé inaperçus en baie d’Auckland. Explications détaillées en vidéo.

America's Cup 2013 - The Boats: AC72 and AC45 Multhulls Compared - from CupInfo | Wing sail technology | Scoop.it

The AC72:

The AC72 is a 72-foot catamaran with a wingsail. These are the boats which will be used in the 34th Defense of the America's Cup in 2013, and in the challenger selection series of the Louis Vuitton Cup regatta.

The AC45 is a one-design 45-foot long catamaran with a wingsail. Identical boats are being built for each team, who will train and race them in the 2011-12 and 2012-13 America's Cup World Series seasons.

AC Uncovered 26. Wing Extensions

This week on America's Cup Uncovered we're in Auckland where Luna Rossa Challenge and Emirates Team New Zealand went head to head for the first time. We have reactions to the testing sessions for the wing extensions, designed to increase the speed of the AC45s in lighter breeze. Then, we in San Francisco to uncover Save the Bay - partner of the America's Cup Healthy Ocean Project. But first, some crew news from Team Korea: White Tiger Challenge announced the recruitment of two current world champion athletes. Australian Nathan Outteridge will replace outgoing skipper and helmsman Chris Draper, who has joined Luna Rossa Challenge. Also joining Team Korea is World and European Finn Champion, Giles Scott, from Great Britain.

The Cars, Planes and Motorcycle That Rocked Our World

America's Cup AC45 and AC72
The 159-year-old America's Cup just got a whole lot faster with the introduction of wing-sailed catamarans.

Racers are training on the AC45, a water-borne rocket that that took just four months to go from concept to creation. The AC45 is but the barest wisp of a catamaran, measuring just 22 feet wide and less than 45 feet long. The sail is actually a wing, and at 70 feet tall it’s longer than the wing on a Boeing 727.

As amazing as it is, the AC45 is but a bantam version of the next-generation America’s Cup yacht, the AC72. That boat promises to make the next Cup the fastest, and most challenging, in history.

Retour sur une sacrée première année. Le Golden Gate Bridge. Il sera sans doute un bon spot pour suivre les courses de l’America’s Cup en 2013 à San Francisco. Sauf les jours où le brouillard emboucane la baie ! Deux événements réservés aux AC45 sont prévus dans la ville californienne l’été prochain.

Wings, the Next Generation
By ADMIN | Published: NOVEMBER 29, 2011
Wanna have some fun? Set Paul Cayard loose on the subject of America’s Cup 34, some re-imagined and surprising wing-control mechanisms, and the terrors of San Francisco Bay in full cry. The custom AC72 catamarans of 2013, he says, will be 30 percent more powerful but “much less stable” than the AC45s that sailed three events this year on the America’s Cup World Series circuit.
