Abstract:
1. A turbine blade assembly comprising: a central rotor having a central axis; a plurality of blades mounted on said rotor to rotate through a plane of rotation, each of said blades lying along a blade axis and having a proximal section and a variable pitch section, said variable pitch section being adjustable to a pitch that may differ from that of said proximal section; and a plurality of stays each extending from said central rotor to approach and terminate on an associated one of said blades, each of said stays having a proximal end spaced from said blades and a distal end attached to an associated one of said blades, the proximal section of each of said blades connecting to the distal ends of a different corresponding trio of said stays, for each of the blades the proximal ends of said different corresponding trio circumscribing the blade axis, each of the stays of the trio distally converging with respect to the other stays of the trio in order to reduce blade deflection front to back and along the plane of rotation.
