跨声速翼型风洞数据库管理系统

本文主要介绍在西北工业大学跨声速翼型风洞(TAWX)中的PC/XT微机上,采用数据库管理软件 C-dBAsE Ⅲ,对该风洞翼型实验数据、计算数据,几何数据和应用程序进行系统化管理的方法。文中着重说明了使用的情况,并针对该风洞的性能、特点,简单描述了所用数据库的结构框图,在此基础上较详细地叙述了实现风洞实验数据共享和存贮的具体过程,其中也涉及到了数据库的管理和维护措施。从文中可领略到使用数据库的好处和必要性。该数据库的建立和开发应用,解决了长期以来实验数据零散、管理困难、使用不便、资源无法共享等问题,提高了工作效率,为实现风洞-计算机一体化的宏伟目标迈出了第一步。

DATA BASE MANAGEMENT SYSTEM IN THE TRANSONIC AIRFOIL WIND TUNNET

This paper presents the case of test data,scientific com-putation data,geometrical model data and systematic management ofthe test program of the wind tunnel,using microcomputer PC/XT anddata base management software C-DBASE3 in the transonic airfoil windtunnel at the northwestern polytechnical university.The practical appli-cation of the software explaieed in detail in the paper.The logic diagramof the used data base was simply described,which is suitable for thequality and characteristic of the wind tunnel.The process to really sharingwith other facilities and storage of the wind tunnel test data was closelydescribed.The management and maintenance of the data base was alsoinvolved in this paper.From the paper,yeaders can realize the advantageand necessity of applying data base to wind tunnel testing.The establishment and application of the data base,the problemshavebeen solved which had existed for a long time,such as the testing dataare scattered, difficult to administer,inconvenient to use and impossbleto share with other facilities.As aresult,the working efficiency has beenpromoted and wind tunnel-computer integration has been made ten tatively.
