民机试飞测试数据处理分析软件设计开发

测试数据是民机试飞过程中的最终产物,是反映飞机系统状态、表明适航符合性的重要依据。 随着大量先进航空总线在民机上的应用,测试数据的体量越发庞大、类型也更为复杂,为测试数据的处理和分析带来了巨大的挑战。 对民机试飞测试数据的类型、存储特点和常用分析方法进行了研究,深入分析了试飞测试数据的处理和分析需求,立足于 WPF( windows presentation foundation)平台,采用 MVVM(Model-View-ViewModel)设计模式,使用了内存管理、DataBinding 事件模型、反射等关键技术,集成了 SciChart、时序数据库等组件,设计开发了民机试飞测试数据处理分析软件。 软件实现了试飞测试数据的快速处理、分析及可视化,可完成多个数据文件的同时加载、进行 1 Hz ~ 16 kHz 不同采样率下数据分析结果的可视化展示,经实际应用,满足了某国产大型客机的试飞需求。

Design and development of data processing and analysis software for civil aircraft flight test

Test data is the final product of the civil aircraft flight test, which is an important basis for reflecting the aircraft system status and showing the airworthiness compliance. With the application of a large number of advanced aviation buses on civil aircraft, the volume and types of test data become larger and more complex, which has brought huge challenges to the processing and analysis of test data. This paper studies the types, storage characteristics and common analysis methods of civil aircraft flight test data. The processing and analysis requirements of flight test data were analyzed in depth. Based on the WPF ( windows presentation foundation) platform, MVVM (Model-View-ViewModel) design pattern was adopted, key technologies such as memory management and DataBinding were used, and components such as SciChart and timing database were integrated. The data processing and analysis software for civil aircraft flight test were designed and developed. The software not only realizes the rapid processing, analysis and visualization of flight test test data, but also can complete the simultaneous loading of multiple data files and perform centralized display of data analysis results with different sampling rates from 1 Hz ~ 16 kHz. The actual application meets the flight test requirements of a domestic large passenger aircraft.
