航空发动机试车数据库系统的设计与开发

Design and Development of the Database System Applied in Areo-engine Test

阐述了航空发动机计算机辅助实验系统中试车数据库系统的设计与开发;首先,介绍了如何采用软件工程的思想对开发过程进行组织和管理,详细讲述了软件工程基本思想及数据库的基本理论;之后,在进行需求分析的基础上构建了SQLServer作为后台数据库管理系统,在Visual C++6.0开发平台上编程实现了航空发动机试车数据库系统中数据的添加、删除、修改、查询等全部数据库管理功能;经过测试,该系统具有响应速度快、稳定性好等优良性能,完全可以胜任航空发动机试车数据的管理工作,已经成功应用于国内某型航空发动机的试车中。

This paper mainly introduced the design and the implement of the database system which was used in aero engine computer aided testing. First of all, the paper discussed how to use the software engineering to organize and manage the process of the system development, then introduced the software engineering and database theory in detail. After that, at the base of the need analyse, the SQL Sever was constructed, the function, including data adding, data deleting, data querying and data modifying, were implemented. Through test, the system can react quickly and the high reliability was realized, the performance was excellent, the system can completely implement the task of aero engine test data management. It has been applied to the test of the engine in our country successfully.
