DEFINITION
Classification: 114/39.3
Reaction rotor-type (e.g., Magnus effect):
(under subclass 39.29) Subject matter wherein the extent of material by which the wind is used to propel the hull through the water is an airfoil rotating through more than 360 degrees about an axis.
(1)
Note. The airfoil may be of the type having a single element rotated about a central longitudinal axis or may be a plurality of integral elements rotated about a common axis.
