How many elastomeric bearings are found on the tail rotor?

The correct answer is based on the design and configuration of the tail rotor assembly in certain helicopters. In particular, this would refer to elastomeric bearings that are used to support the tail rotor system, allowing for necessary movement and dampening vibration during operation. Specifically, the use of eight elastomeric bearings plays a critical role in enhancing the performance and reliability of the tail rotor by enabling smooth articulation while maintaining structural integrity. These bearings provide essential flexibility to accommodate the various forces acting on the tail rotor, including aerodynamic loads and torque reactions.

This configuration is integral to the overall operational safety and efficiency of rotorcraft, as it aids in noise reduction and prolongs the service life of mechanical components involved in tail rotor functionality. Knowing the exact number of elastomeric bearings helps maintenance personnel to be accurate in their inspections and repairs, ensuring readiness and safety during flight operations.
