Latest Patents

One of his latest patents is a low drag, bearingless rotor head for helicopters. This invention provides a low drag, bearingless coupling between a blade and hub of a helicopter rotor system. The coupling is achieved through a planar, elastic flexure that extends between the blade and the hub in a generally azimuthal direction within the rotor plane. The flexure's thickness is designed to be smaller than the adjacent blade or hub thicknesses, ensuring that its aerodynamic cross-section presented to airflow is negligible. The flexure is characterized by a bend in the coupling between the hub and blade, and it is illustrated as an integral, 'W'-shaped component with a 'U'-shaped segment extending between each side of the adjacent blade and hub arms. The flexure can be constructed from a rod with a circular cross-section or a flat plate shaped to possess the desired elastic and resilient characteristics.
