Abstract:

This report presents the results of a design study of repairable main rotor blades. The designs studied are applicable to the Armys UH-1H helicopter with semirigid teetering rotor system. The program included development of analysis methodology, including a model for rotor blade life cycle costs, establishment of design concepts, analysis of these concepts from both a technical and cost viewpoint, and selection of a final recommended configuration for future development. As partial support for the concept of field repairability of rotor blades, an experimental evaluation of a major repair was conducted under simulated field conditions. The procedure used and the results of this evaluation are included as an appendix to this report.
