Abstract:

The effort is concerned with the application of graphiteepoxy and graphitepolyimide composite materials in the design of both a conaxial compressor and a centrifugal compressor. The first part of the program involved the study of a composite conaxial compressor to determine the fabrication and structural feasibility of producing such a compressor. This composite compressor would be capable of 2000 feet per second tip speeds and would be applicable to small engines. The second part of the program involved the study of a centrifugal compressor that was to be constructed of advanced composite materials substituted on a functional-replacement basis with the current titanium material with the objective of arriving at a cost-competitive component. Structurally feasible designs for both the coaxial and centrifugal components were developed under the constraints set in the program. It is doubtful that composites can be utilized on a cost-competitive basis in the centrifugal compressor application unless the economics of high-volume production can be utilized to justify the cost of the necessary specialized automated equipment. It is recommended that future effort be directed toward the development of the composite conaxial compressor, since a major advance in axial compressor technology is possible. Author, modified-PL
