Aero-engine Design, A Shared Database And Web Application Development

The Aeronautic Engine Sharing Database is the external cooperation projects of Beijing University of Aeronautics & Astronautics. This database is a combination of the need to build a database of aeronautic engine sharing platform in order to preserve the industry-wide test data and manage effectively. Thus, it is used to support for research and Aero Engine Simulation of technical support.In this thesis, it discussed the principle and the main technical methods, which on based Web application database, and analysed the status of domestic and abroad, and introduced the general situation of application in the field of aero-engine database system. The solution of program design has also been given. The main contents are as follows:1.Through analyzing the Aeronautic Engine Sharing Database's demand, the conceptual models,the logical models have been designed. The E-R diagram and tabular are also designed. In accordance with the information and the relation of the aero-engine components, it has made data structure design, built to 10 of professional data structures.2.Web-based application on the database architecture has been investigated, the current situation of relation database has been analyzed, and the merits of accessing to the database through Web have been listed.3.The design and implementation of the Aeronautic Engine Sharing Test Database have been described. The functional design, the technology of carrying out, and the application of program have been discussed. The choice of a database,the program design tools,the development methods and the procedures design process have been described. In software program, it focus on the application of the Web-based query system and post-processing system, including query,data playback,curve,mathematical data processing and output data.In short, over a long period of design data and valuable test data, performance analysis data are stored in the database. In this unified platform, established a management system including engine, the core of machines, parts and components of aero-engine. Thus, this database can provide strong technical support for the various types of advance research for aero-engine.The research results provide reference for the investigation of other databases.
