Research On Distributed Simulation Of Aero-engines

Distributed simulation can save time and money in design and development of engine, playing a very important role in each phase of aeroengine development. In this thesis the distributed simulation environment is investigated which provides capabilities of component integration, variable complexity analysis and multidisciplinary coupling and it presents an excellent platform and solution accounting for this goal. Aeroengine distributed simulation systems based on both serial components level and parallel full engines level are developed.A component level aerothermodymamic model of a turbofan aeroengine is created in this thesis using OO technology. As an open-source middleware ACE/TAO which complies with CORBA standard is used as communication infrastructure, model's task is decompounded to constitute an aeroengine distributed system based on component level.A concurrent simulation interface for full engine is defined, and then server and client programs are developed through co-coding the skeleton and stub which come from compiling predefined IDL file, according to resolving the nonlinear equations group of concurrent distributed model. The GUI is designed based on MFC.Simulation tests indicate that it is easy to use, maintain and extend and also can improves the performance of complex simulation task remarkably.
