Latest Patents

Sonneborn's latest patents include a "Twist control for helicopter tail rotor pitch change." This invention features a control mechanism for a helicopter tail rotor, where inboard twist sections on opposite sides of a central hub section are adjacent to pitch horns mounted outboard the margins of the twist sections. These extend to a negative delta connection point located at the virtual bending axis of each twist section. The rotor teeters on the tail mast, with the span axis of the rotor at an angle of approximately 30 to 45 degrees from the teetering axis. Another significant patent is the "Soft in-plane helicopter rotor." This design includes a helicopter rotor hub assembly where a blade grip extends inboard of a yoke and transfers centrifugal forces to the yoke through a spherical elastomeric bearing. The pitch change of the grip and blade is accommodated by this bearing, which also serves as the pivot point for lead-lag motion of the blade and grip.
