Gas Turbine Simulation Integration and its Distributed Object Implementation

In order to systematically, rather than analytically investigate the interdisciplinary phenomenon during the engine's life cycle,the concept of gas turbine simulation integration is proposed.The technological obstacles in its realizeation are identified.Then a prototype distributed object implementation is presented from the viewpoint of the cross platform attribute of the simulation integration.For engine overall performance simulation based on its components' performance on a heterogeneous distributed computing platform,the IEEE standard for distributed object computing,CORBA,is conformed throughout the implementation.The implementation is tested on a network environment consisting of 3 Pentium Ⅱ PCs and 1 SUN Ultra 1 workstation interconnected through a LAN.The functionality of simulation integration is fully verified and various simulation results of different configurations are presented and analyzed.It is concluded that,without real time support,the above implementation can only be used in interdisciplinary researches not requiring any real time capabilities.Some potential applications of the implementation,including remote collaborative engine design and simulation,are also proposed.
