| Compressor is one of the most important parts in the aeroengine, because the designing work is critical for the performance of engines to a degree. And the aerodynamic design of the compressor depends on software design platform to a great degree.In this dissertation, there is an introduction of the development of compressor and the technology of compressor, and the status of CFD software is illuminated, the development of thoughts of design of compressor and its system in the developed countries in recent 50 years is summarized. And that in China is also analyzed. In the view of need of the development of aeroengine in china, the software platform with our own intellectual property for compressor aerodynamic design should be developed.The article is based on the theories and methods of the compressor design, guided by compressor design system, and the advantage and defect of the compressor designing software platform is analyzed. And a software design platform for compressor is developed, which is coded in the environment of Visual Studio2003.NET which is the production of MICOSOFT Co. and the software platform includes thermodynamic calculation platform, one-dimension design calculation platform in varying work condition and the platform for compressor design of Quasi-3D, and this software is designed with the theories in software engine. Then, the developing thoughts, functions, user interface, coding environment and language, and technologies are explicated.In this article, A array of compressors are designed by the software platform, and this calculating examples are validated, including thermodynamic calculation, one-dimension designing and characteristic calculation, and the compressor design of Quasi-3D including S1 flow surface, S2 flow surface and blade molding.And the validity and usability of this software system is proved by computing and analyzing these calculating examples, finally, the value of software system in engineering is proved.
