一种基于RIA结构的飞机载荷谱数据库系统设计方法

 针对基于Web方式处理飞机载荷谱实测数据及载荷谱编制过程中结构化和非结构化数据共存、客户端实测数据处理能力弱和大量网络数据传输量等问题，提出了基于富互联网应用程序(RIA)体系的数据层、业务逻辑层、表示层和客户端软件层的4层结构资源管理模型，利用ASP.NET技术构建飞机载荷谱数据库系统，客户端软件层通过自定义协议向服务器发送请求并获取处理实测数据，构成了富客户端，增强了客户端浏览器对试验数据的处理能力，使飞机载荷谱实测数据管理与处理方式由单主机方式或基于局域网共享方式转变为基于Web方式的实测数据和相关资源的管理与共享，为飞机机构定寿、延寿和设计工作提供科学依据。

A Method to Design Aircraft Load Spectrum Resources Database Based on RIA Framework

Many problems exist in processing experimental aircraft load spectrum data and generating the load spectrum based on Web application, such as the need to deal with both structural and non-structural data, weak capacity of the client browser for data processing and massive network data transferring, etc. To solve the above problems, a four-layer resource management model is established based on rich internet application (RIA), which includes a data layer, a business logic layer, a presentation layer, and a client software layer. The aircraft load spectrum data storage and management system is developed by ASP.NET according to component conception, in which the client software layer sent requests and treated experimental data using custom protocol from the document server group. In the four-layer system, the client software (rich client) with built in browser is enhanced to process and share real-time experimental data. The resource management system changed the method to process aircraft experimental data, and the way to data treatment by single host or local area network (LAN) sharing is abandoned. The new pattern based on Web applications can provide scientific basis for aircraft life determination, extension, and deign through an experimental data management and sharing system.
