One of the objectives of the High Performance Computing and Communication
Project's (HPCCP) Numerical Propulsion System Simulation (NPSS)
is to provide a common and consistent way to manage applications,
data, and engine simulations. The NPSS Configuration Management
(CM) File Manager integrated with the Common Desktop Environment
(CDE) window management system provides a common look and feel
for the configuration management of data, applications, and engine
simulations for U.S. engine companies. In addition, CM File Manager
provides tools to manage a simulation. Features include managing
input files, output files, textual notes, and any other material
normally associated with simulation. The CM File Manager includes
a generic configuration management Application Program Interface
(API) that can be adapted for the configuration management repositories
of any U.S. engine company.
Guided by emerging desktop standards, a team consisting of NASA
Lewis Research Center personnel and representatives from U.S.
engine and airframe companies defined, developed, and implemented
a standard graphical user interface windowing system for launching
and administering simulations with configuration management access
functions and file management tools. The NPSS CM File Manager
contains a common windowing system based on CDE that contains
the necessary tools an engineer requires for designing and analyzing
engines. The software was developed following I. Jacobson's Object-Oriented
Design methodology and was implemented in C++.
In March and June of 1996, Lewis released beta versions of the
NPSS CM File Manager. In September of 1996, Version 1.0, with
documentation, was released to U.S. engine companies.
The development of the NPSS CM File Manager provides U.S. aeropropulsion companies a common tool for creating and modifying engine simulations. Since the CM File Manager was built on a desktop standard (CDE), it is easy for engine companies to use, accept, and manage. In addition, U.S. engine companies could save millions of dollars by using standard analysis and design tools in precompetitive areas.
During fiscal 1997, NPSS will accept enhancements and modifications
to the CM File Manager. The modifications will be done by a third
party that can provide long-term software support.
