AS681H Gas Turbine Engine Steady-State and Transient Performance Presentation for Digital Computer Programs

This Aerospace Standard (AS) provides the method for presentation of gas turbine engine steady-state and transient performance calculated using digital computer programs. It also provides for the presentation of parametric gas turbine data including performance, weight and dimensions computed by digital computer programs.

This standard is intended to facilitate calculations by the program user without unduly restricting the method of calculation used by the program supplier.
