This document is the first part of a two part volume of detailed Users Guides for the computer programs of a new transonic wing design procedure. Part 1 presents the Users Guide for the transport design programs produced by Lockheed-Georgia Company and Part 2 presents the Users Guide for the fighter design programs. The purpose of the contract was to develop and validate a new transonic wing design procedure using the numerical optimization technique. The new procedure was used to design both a transport and a fighter configuration. Because the missions and design requirements of a fighter and transport are so different, the design procedure was developed along parallel lines. Lockheed-Georgia Co. developed the transport design procedure, and Grumman Aerospace Corp. developed the fighter design procedure. Users guides for the computer programs used in the transport design case study for the aircraft design procedure developed as part of the Advanced Transonic Technology ATT program are presented. These programs include two 3D transonic wing analysis codes linked to a numerical optimization routine, a two dimensional strip boundary layer program and a wing-pylon-nacelle interference program. The input data required by each program is described in detail. Samples of the output from each program are presented. Author
