Available in PDF, EPUB and Kindle. Book excerpt: This report describes a digital computer program that calculates static stability, high lift and control, and dynamic derivative characteristics using the methods contained in sections 4 through 7 of the USAF Stability and Control Datcom (revised January 1974). Configuration geometry, attitude, and Mach range capabilities are consistent with those accommodated by the Datcom. The program contains a trim option that computes control deflections and aerodynamic increments for vehicle trim at subsonic Mach numbers. Volume I is the user's manual and presents program capabilities, input and output characteristics, and example problems. The program is written in ANSI Fortran IV. The primary deviations from standard Fortran are Namelist input and certain statements required by the CDC compilers. Core requirements have been minimized by data packing and the use of overlays. User oriented features of the program include minimized input requirements, input error analysis, and various options for application flexibility.
