Computer Aided Advanced Design and Performance of Airborne Vehicles.
Description of an operations research tool for easily determining the gross design and performance parameters of almost any proposed airborne vehicle: a comprehensive system of computer routines, modularized down to the level of basic analyses of fundamental hardware components, and assembled into logical subsystems that are independent of vehicle configuration. A prototype FORTRAN IV implementation, including over 130 subroutines, 18,000 IBM cards, and 17,000-element databank, can be used by employing only 10 or 20 cards. It comprises REGSYS, for determining empirical weight-estimating relationships through multiple regression analysis, and AIRSYS, for design and performance analysis. Programming a final version would probably be too burdensome for any one organization, but the overall program is so arranged that separate aerospace research groups could contribute their proved programs to make a tool usable by all. (Intended for the MORS 1970 Symposium, the document consists mainly of briefing charts.) 28 pp.
