Advanced Structures Maintenance Concepts.

Abstract

A detailed R&M analysis was conducted for an advanced composite rear fuselage for the UH-60A Black Hawk helicopter. Methods of improving the damage tolerance of the structure in areas of high impact exposure were evaluated. Cost-effective R&M options were recommended for incorporation in the design. Materials and techniques for performing rapid, low-skill-level repair of composite airframe structures in the Army field environment were investigated. Epoxide-impregnated preform patches were evaluated for repair of primary structural components. Polyurethane foam kits were studied as a potential method of creating forms and mandrels for laminating repairs on the aircraft. A modular design concept was developed for the UH-60A composite rear fuselage. Module replacement methods were defined. Studies were conducted to assess the economics of modular maintenance versus conventional types of repair. Potential improvements in combat repairability were evaluated. (Author)
