SwRI to Manage Numerical Propulsion System Simulation (NPSS) Consortium
SAN ANTONIO --(Business Wire)--
Southwest Research Institute (SwRI (News - Alert)) has been awarded a contract to
become the manager of the Numerical Propulsion System Simulation (NPSS)
Consortium. NPSS is an advanced object-oriented, non-linear
thermodynamic modeling environment used by the aerospace industry for
modeling turbo-machinery, rocket engines, environmental control systems,
ducting, vapor cycles and other equipment and phenomena. SwRI will
assume responsibility for the consortium May 1.
NPSS originated in the 1990s as a NASA Glenn Research Center project
with a focus on developing a rapid simulation capability for engine
"As industry adopted the software tool, it became more important to
aerospace companies because it allowed for collaboration and model
sharing for integration with other vehicle system models," said David
Ransom, manager of the Machinery Structural Dynamics Section in SwRI's
Mechanical Engineering Division. "The NPSS Consortium was formed, and
NASA licensed the software to the consortium so industry partners could
continue developing it for their needs."
Member companies se the software for preliminary design of new engine
systems, sharing engine models across companies and correlating with
actual engine test data. Current member companies include a number of
major engine manufacturers and aerospace companies, as well as NASA.
Ransom noted that other companies and universities have purchased
commercial licenses of the software for modeling a variety of systems
including industrial gas turbines and concentrating solar power systems.
As consortium manager, SwRI will provide overall project management and
engineering support for maintenance and development activities as
directed by the member companies.
Ransom said consortium goals for 2013 include completion of a graphical
user interface for NPSS to reduce learning time for new users and adding
an improved thermodynamic fluid properties modeling capability for fluid
flow elements, including the ability to model multi-phase flow for
refrigeration cycle models.
NPSS can be obtained by either the purchase of a commercial license or
through consortium membership. For more information about NPSS, contact
Ransom at (210) 522-5281 or firstname.lastname@example.org.
SwRI is an independent, nonprofit, applied research and development
organization based in San Antonio, Texas, with nearly 3,000 employees
and an annual research volume of more than $584 million. Southwest
