A KNOWLEDGE-BASED PROPELLER CAD SYSTEM

Till now CAD systems have been used as a tool helping the practical computer design, containing sequence of computational procedures, applied to the abstract models of the objects to be designed. Within the last years the development of expert system shells have permitted their coupling with CAD systems to produce the new challenge - the intelligent CAD. This paper describes the methodology and the results of developing a knowledge-based system for screw propeller design, having new mechanisms for advice and expert knowledge support. The shell is based on OPS5-like language, having all the features of manipulating the knowledge and data base. It performs control functions in the integrated system giving control to different numerical and graphical CAD procedures. Several propeller design rules have been incorporated in the knowledge base. Some examples illustrating the performance of the system are presented. The system is a user - friendly tool for the designer and is open to further development.
