The regatta, supported by the St . Barth Yacht Club brings together six classes of yachts, including maxis, a class of giant prototype boats fitted out with the latest equipment and experimental technology for ocean racing, like rotating wing masts.
He also designed the prototype for a flying machine with a rotating wing similar to today's helicopters.
This causes a unique dynamic time-lag phenomena of lift generation for FRW, unlike the normal flapping wing flight vehicle driven by its own motor to actively rotate its wings.
It was even dual purpose: rotate its wings and it turned into a drinks table.
For example, Dickinson suspects that insects maneuver by changing the point in the stroke at which they begin to rotate their wings.

But the sea butterfly "flies" (see video), generating lift by rotating its wings and body in a figure 8, almost clapping the wings together at the top of the stroke just like a small flying insect, the team reported in the Journal of Experimental Biology.
If the insect rotates its wing before starting the return stroke, the wing can intersect its own wake and capture extra oomph to keep the insect aloft.
