Abstract : The NAVAIRDEVCEN (Naval Air Development Center) is a large user of vehicle and propulsion design and performance computer codes and is constantly seeking to improve their efficiency and flexibility. A significant number of these codes are dependent on the use of input tabular data sets. Quite frequently these data sets are initially received in a format incompatible with direct use in these codes, resulting in a time consuming, error prone transformation task. To circumvent this problem, development of a rapid data transformation code was undertaken. The impetus for this effort was the need to prepare for a planned substantial increase in analyses of various aircraft and propulsion system. This present report describes a code based on the use of an interactive graphics system that permits direct creation of digital tabular data sets from material in graph form, utilizing a Tekronics 4015 graphics terminal, digitizer tablet and hardcopy unit. In addition the user may edit and correct these data directly from the digitizer tablet or from the graphics display screen using cursor cross hairs and tablet commands. This code, entitled TIGS(Table Plot Interactive Graphics System) was developed using the NAVAIRDEVCEN CDC 6600/Cyber 175 computer facilities. A user's guide for this code is shown in Appendix A. A Fortran listing ot he TIGS code is shown in Appendix B.
