Integration of Hybrid Structure into Low-Cost Aircraft Design - Rationale and Methodology.

Abstract

This report contains the rationale and methodology for using a blend of advanced metallics and advanced composites in the design of low-cost, low-weight aircraft. A systems engineering approach is developed via an example using a previously designed fighter aircraft as a baseline. The criteria for improvement is low life-cycle-costs for derivatives of the baseline aircraft that meet the specific performance measures. The rationale and methodology displayed pertains to the use of structural materials and associated manufacturing processes for airframe construction. The emphasis is on cost related decisions made during the conceptual design phase. This report contains a description of the salient properties of materials, typical material applications, and a description of the manufacturing processes associated with the materials. The rationale and methodologies described can be used for conceptual design of all types of aircraft. The specific results obtained are indicative of the value of advanced metallics and advanced composites. From a cost viewpoint, it is concluded that research and development of both advanced metallics and advanced composites should be continued. (Author)
