Standards Approach to Design-To-Cost of Composite Airframes

General Dynamics proposes a unique approach to the problem of airframe cost estimation. This approach involves identification of detail airframe parts and automated specification of a complete manufacturing plan. A procedure such as this provides credible manufacturing cost estimates for new technology areas, such as advanced composites, and provides a systematic methodology whereby design-to-cost evaluations may be incorporated in early configuration design. The procedure's design, its development for composite materials, and specifically the construction of an automated composites manufacturing plan are discussed. 10 refs.
