Abstract
The NASA Numerical Propulsion System Simulation
(NPSS)
project is exploring 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 of a simulation
executive that addresses each of these 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 has been designed for this
simulation to support experimentation with expert system techniques for
active control of the simulation. An interconnection system provides a
transparent means of connecting the heterogeneous systems that comprise
the prototype.
