Title
(R) Gas Turbine Engine Performance Presentation and Nomenclature For Object-Oriented Computer Programs
SAE International
Publication Date:
Dec 1, 2008
Scope:
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.
