Implementing Monitoring and Zooming in a Heterogeneous
Distributed Jet Engine Simulation
Abstract
The NASA Numerical Propulsion System Simulation project explores the use of
computer simulation to facilitate the design of new jet engines. Several key
issues raised in this research are being examined in an NPSS-related research
project: zooming, monitoring and control, and support for heterogeneity. The
design and implementation of a distributed simulation executive that addresses
each of theses issues is described.
In this work, the strategy of zooming, which allows codes that model at
different levels of fidelity to be integrated within a single simulation, is
applied to the fan component of a turbofan propulsion system. A prototype
monitoring and control system provides continuous updates on the progress
of the simulation and a platform for experimenting with active control
techniques. An interconnection system provides a transparent means of
connecting the heterogeneous systems that comprise the prototype.
