A lift generating method and apparatus for aircraft is provided which generates lift in forward flight, in vertical flight or while hovering. A disk (24) is positioned between first and second counterrotating blade assemblies (22 and 36). The disk (24) generates lift in vertical flight or while hovering due to radial flow of air over an upper surface (28) thereof. In forward flight, the disk (24) functions as a fixed wing to generate lift. The assemblies (22 and 36) may be rotated to provide equal and opposite torques so that a torque compensating tail r...
An apparatus for generating lift in forward and vertical flight, comprising: blade means, rotatable about a substantially vertical axis, for imparting motion to air in a downward direction; and disk means, disposed beneath and operatively separated from said blade means, formed in the shape of a circular airfoil such that said disk means functions as a wing to generate lift in forward flight, said disk means having a vertical depth which is between about 5 to 20 percent of the diameter of the disk means and including a convex upper surface defined by an ...
