Extending the Flexibility of Object Oriented Systems Modeling Architectures

Abstract

When adopting an industry-wide generalized modular based system simulation tool (such as the Numerical Propulsion System Simulation – NPSS™), the generic modules provided with the system do not typically provide the fidelity required for detailed engineering design and analysis nor do they necessarily align with company specific methods. The challenge is to develop company specific replacement modules that would promote standardized methodologies while still providing the flexibility required for unique methods and / or joint venture teaming arrangements. Pratt & Whitney (P&W) has developed such a system within the NPSS™ framework that leverages the intrinsic Object Oriented (OO) capabilities of this tool without compromising the integrity of the standard methodologies. This flexibility easily allows a single system to be used for engine systems modeling from Concept Initiation through Fielded Product Support. Additionally, the structure and capabilities of this newly developed system provides the means for a significant reduction in the manpower required to maintain / upgrade this toolset.
