Abelly Autogyro Rotor Head
rotor head is designed and machined to our exacting standards.
We use the highest quality, full-complement, dual-row, angular contact sealed bearing available. A ¾" gimbal offset with an accompanying trim spring add dynamic stability to the aircraft.
A hydraulic rotor brake system is integrated directly into the torque tube. The brake pad assembly is pushed outward to the ID of the PR ring gear much like a drum brake.
The outward force of this system is much more effective than traditional style rotor brakes that push upward on the bottom of the ring gear and cause excessive flexing of the disk assembly.
When disengaged, the brake pad retracts slightly away from the ring gear and is completely clear of the rotating components, with no chance of interference during flight.
Plastic teeter-stop inserts prevent metal-to-metal contact of the hub bar and rotor head.
Choose your desired input for the Bendix unit. Rigid shaft (5/8″), Flex shaft adaptor, or Hydraulic motor mount.
Custom height teeter-towers are available to match the under-sling of your rotor system
