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.
