Abstract:

This report uses the results of Contract DAAJ01-73-C-0282P3L, Elastic Pitch Beam Tail Rotor Study for LOH Class Helicopters, and Contract DAAJ01-72-C-0006, Elastic Pitch Beam Tail Rotor, for selecting the most promising concepts to establish detailed designs that are applicable to LOH class helicopters. The designs studied herein included removablereplaceable blade airfoil shells, damageerosion-resistant leading edge, and damage tolerantrepairable trailing edge. The elimination of bearings was an important design objective where bearings were required, consideration was given to the use of elastomeric bearings. Improvements in reliability and maintainability, repairability, cost, performance and producibility along with interchangeability with existing tail rotor systems were also prime considerations in the design selection.
