Abstract Computer programs developed to handle the computational tasks for the linear stability analysis of propulsion controls by root locus techniques are described. The descriptions, flowcharts, and Fortran program listings of two main programs TJET and TFAN developed for the analysis of turbojet and turbofan engine control systems are presented. Also presented are the descriptions of three subroutines specially developed to facilitate data handling for this study. Examples are given to illustrate the application of computer programs TJET and TFAN. (Author)
