Abstract

Design concepts of low-cost lightweight composite engine frames were applied to the design requirements for the frame of commercial transport high-bypass turbine engines. The concepts included generic-type components and subcomponents that could be adapted for use in different locations in the engine and to different engine sizes. A variety of materials and manufacturing methods were assessed with a goal of having the lowest number of parts possible at the lowest possible cost. Evaluation of the design concepts resulted in the identification of a hybrid composite frame that would weigh about 20% less than the state of the art metal and cost about 40% less.
