M E Talley, R N Mueller: 1072. An Approach to Integrated Cost/Weight Design Methodology. 1975.



The current emphasis on cost analysis and the design-to-cost philosophy within DOD has created an immediate need for analytical methods which can rapidly and accurately estimate the cost of a specific aircraft design. This paper discusses the detail which can and will be required in preliminary design studies to achieve sensitivity to the cost driving design parameters. Some limited experience with new D-T-C methods has revealed that implementation of the system for D-T-C programs will require:
(1) A common format for cost and weight data.
(2)Manufacturing analysis suitable to preliminary design.
(3)Assessment of damage tolerance criteria on cost and weight.
(4)Detailed tracking of cost data in advanced technology programs.
