Product Code:SAE AS681
Title:Gas Turbine Engine Performance Presentation for Computer Programs
Issuing Committee:S-15 Gas Turbine Perf Simulation Nomenclature And Interfaces
Scope:This SAE Aerospace Standard (AS) provides the method for presentation of gas turbine engine steady state and transient performance calculated using computer programs. It also provides for the presentation of parametric gas turbine data including performance, weight and dimensions computed by 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. This standard is applicable to, but not limited to the following program types: data reduction, steady-state, transient, preliminary design, study, specification, status & parametric programs.
