Elastic Pitch Beam Tail Rotor Study for LOH Class Helicopters.

Abstract

This report studies the feasibility of using the flexural concept of the Elastic Pitch Beam in the design of tail rotors for LOH class helicopters. The goal is to provide reliability, maintainability, repairability, and performance characteristics that are improved over those of current designs. Specifically the designs studied included individually replaceable airfoil panels, a minimum number of bearings, elastomeric bearings where bearings are required, and composite materials to improve damage tolerance and repairability. Comparative analyses were used to select the preferred configuration to be subjected to further study. (Author)
