The program can be used to analyze power systems having any number of shafts up to a maximum of five. On each shaft there can be as many as five compressors and five turbines, along with any specified number of intervening intercoolers and reheaters. A recuperator can be included. Turbine coolant flow can be accounted for. Any fuel consisting entirely of hydrogen and/or car¬bon can be used. The program is valid for maximum temperatures up to about 2000 K (3600° R). This report presents the system description, the analysis method, a detailed explanation of pro¬gram input and output including an illustrative example, a dictionary of program variables, and the program listing.
