Design And Implementation Of Data Management System For Wind Tunnel Test Data Based On C/S Mode

Wind tunnel test is an important method to obtain aerodynamic characteristic of aircrafts.Due to the large numbers of wind tunnel tests,enormous aerodynamic data has been stored.How to manage and use these data has be come a general problem.With the help of information technology,database has been applied to address this problem,and a wind tunnel database management system has been developed accordingly.At the beginning of thesis,related research background was introduced.After that the overall structure of the wind tunnel test data management system based on the demand analysis of wind tunnel business process was designed.C/S architecture was introduced and SQL Server 2005 was selected as the system's database pl atform.ADO technology was used for the connection between application program and the database.The details of design scheme,realization method of the sub-module were discussed.The system testing process and results were described.The final part of the thesis included a summary and improvement need to be further discussed.The system realizes the class-based storage and management of wind tunnel test data,photos and reports;provides function of data batch input,browse and query;as well as data processing,including interpolation,calculation of the trim attack angle and rudder efficiency.The system implemented database access control,and security function.At present,the wind tunnel test data management system has been applied.Experiments and trial operation show that the overall system design is reasonable and the solution is feasible.
