The CADAM ® System for Aircraft Structural Design 801208

The use of interactive computer graphics for aircraft structural design is discussed. The software used is the Lockheed-California Company Computer-graphics Augmented Design and Manufacturing (CADAM)® system in conjunction with our inhouse Surface Design and Finite Element Model programs. Starting with the conceptual design on the CADAM system, configuration geometry is generated for use by analysis users, preliminary design, loft, and production design organizations. An example used to demonstrate the application of the system is the development of a smaller horizontal tail for L-1011 derivatives, under the sponsorship of the NASA Energy Efficient Transport Technology office. The increased productivity achieved by using the CADAM system is described.
