This document provides recommendations for several aspects of air-breathing gas turbine engine performance modeling using object-oriented programming systems. Nomenclature@ application program interface@ and user interface are addressed with the emphasis on nomenclature. The Numerical Propulsion System Simulation (NPSS) modeling environment is frequently used in this document as an archetype. Many of the recommendations for standards are derived from NPSS standards. NPSS was chosen because it is an available product. The practices recommended herein may be applied to other object-oriented systems. While this document applies broadly to any gas turbine engine@ the great majority of engine performance computer programs have historically been written for aircraft propulsion systems. Aircraft and propulsion terminology and examples appear throughout. Purpose The purpose of this document is to define an object-oriented paradigm for the simulation of gas turbine engine performance@ recommend nomenclature for objects and variables within such a simulation@ and recommend practices for user interaction with such a simulation. Field of Application This document applies to air-breathing gas turbine engine performance simulations using an object-oriented programming approach.
