Abstract:

The construction of expert system,especially the methods of knowledge representation in conceptual preliminary design of Solid Rocket Motors(SRM) is presentedA computer program with expert knowledge base and design optimization was developed by use of Borland C++ Object Oriented Programming (OOP) for Windows and Fortran languagesWith the assistance of the code,design engineers can quickly perform prototype design of SRM that satisfies the performance requirements of SRM,and meets design criteria for minimum motor mass and total impulse ratioThe purpose of expert system is to save our knowledge accumulated from practice about the SRM design,aid the new designers in making their best initial design parameter selections and deliver some suggestions for the general schemeThe functions of the code are demonstrated by designing a metal case SRM
