Calculations from a Mathsoft workbook are similar to those used by Lockheed engineers working on the F-35. The software documents and shares the equations so others can substitute their values to run comparable structural studies. Mathcad also integrates with FEA and CAD programs. |

Engineers with the Joint Strike Fighter program at Lockheed Martin Aeronautics Co. use mathematics software to document aircraft design calculations. Mathcad, from Mathsoft Engineering & Education Inc., Cambridge, Mass. (www.mathsoft.com), lets JSF engineers record inputs, assumptions, methods, calculations, and results that drive the F-35 structural design process and improve efficiencies in design, quality, and productivity of the development work.

"The software will run and document critical calculations, and serve as a design repository for underlying assumptions behind the calculations," said Glenn Morris, specialty lead for structural analysis at Lockheed Martin. "The software also allows more aggressive mathematical analysis, which helps speed design and investigate ways to lower the aircraft's weight."Mathcad's centralized repository also links the JSF Program Office and team members to other Lockheed Martin offices.
