    expensive, actual system (e.g., a flight simulation vs. use of multimillion dollar aircraft) Modelling Concepts There are several concepts underlying simulation. These include system and model, events, system state variables, entities and attributes, list processing, activities and delays. This concept is called the Numerical Propulsion System Simulation (NPSS). NPSS consists of three main elements: (1) engineering models that enable multidisciplinary analysis of large subsystems and systems at various levels of detail, (2) a simulation environment that maximizes designer productivity, and (3) a cost-effective. high-performance.

This paper describes the development of the numerical propulsion system simulation (NPSS), a modular and extensible framework for the integration of multicomponent and multidisciplinary analysis tools using geographically distributed resources such as computing platforms, data bases, and people.

      As shown in the plot below, the results are in good agreement with a reference data (analytical approach). The solid squares are the numerical results from the simulation, and the outlined circles are the reference results. Comparing the film thickness (blue) and pressure (green) between the numerical results and the reference. Image courtesy. 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.

[Karen M Meinert; Langley Research Center.;]. Numerical Propulsion System Simulation (NPSS): An Award Winning Propulsion System Simulation Tool The Numerical Propulsion System Simulation (NPSS) is a full propulsion system simulation tool used by aerospace engineers to predict and analyze the aerothermodynamic behavior of commercial jet aircraft, military applications, and space transportation.

Starting in the early s, a fifth cycle analysis era began with the development of Numerical Propulsion System Simulation (NPSS) via a collaboration between industry and NASA.

NPSS expanded on the modular structure of the previous era and also made improvements to enable multidisciplinary and multi-fidelity engine analysis [ 10, 11 ]. American Institute of Aeronautics and Astronautics Sunrise Valley Drive, Suite Reston, VA - the Numerical Propulsion System Simulation.

NPSS is a concerted effort by NASA Glenn Research Center, the aerospace industry, and academia to develop an advanced engineering environment – or integrated collection of software programs - for the analysis and design of aircraft engines and, eventually, space transportation components.
