|Virtual Wind Tunnel (VWT), was originally developed jointly by Dartmouth College Thayer School of Engineering and North Sails and is now run by the Stevens Institute of Technology. VWT is the first (and still the only) computer simulator to accurately model wind flow on downwind sails at 100% scale. When first developed, North Sails used the world’s two leading low-speed wind tunnels (North’s own Twisted Flow Wind Tunnel and Oracle’s IACC Twisted Flow Wind Tunnel) to verify it’s accuracy. The results have given us great confidence that North’s “VWT” predicts results with more accuracy than wind tunnel sail testing of any kind. VWT provides powerful insight into flying sail shape, sail drive, shape stability and ease of trim.|
Unique to VWT is its ability to integrate with Membrain allowing both upwind and downwind sail shapes to be analyzed with unprecedented accuracy.
