This article introduces the EngineCAD microcomputer integrated design system using the latest technology in the design and modification of aeroengine. The system can realize the parametric real-time design of the components and general plans of turbojet, turbofan, turboshaft and turboprop engines, and provide engine information database and interactive query of structure database in the parametric design process, The required information, data and structural graphics support can be quickly generated for the program demonstration applications of various aircraft engine parts map, the total map and a variety of information, and can quickly achieve multi-program design. Specific application shows that the use of the system greatly shortens the design cycle, improve the success rate of a design, reducing design costs
