An extensible propulsion simulation platform Part I-foundations of engineering model

EPSP(extensible propulsion simulation platform) was developed as a Java-based object-oriented platform for propulsion system simulation.The architecture represents the hierarchal structure of the engine,its components and substructures using recursive composition.This paper presents the design of a common engineering model framework for use in EPSP.This technique provides an access to build models with increasingly complex elements out of simpler ones.The foundations of the platform's engineering model were described.To test the platform,we can easily construct a component based engineering model,and the "pluggability" of the architecture is shown.The example proves the validity and feasibility of the modeling of the platform.
