云技术在飞行试验数据处理中的应用

Application of Cloud Technology on Flight Test Data Processing

针对飞行试验数据的海量非结构化的特点以及当前所面临的处理与应用问题,研究分析当前新兴的云技术,提出了飞行试验数据云计算应用架构的3个组成要素:设备系统、云存储和云计算。面向试飞数据工程应用,以试飞科目、试验动作段为频度矩阵建立试飞元数据存储阵列,实现海量非结构化试飞数据的云存储应用;以SOA架构为基础,结合面向应用的处理功能组件,实现分布式网络计算调度和计算群集,为用户提供高效的云计算服务。工程实践应用表明,该系统以灵活架构有效地解决了非结构化大数据信息的高效存储、统一管理和共享应用,实现了海量试飞数据的快速分析处理,展示了云计算技术的先进特点。

Aiming at the massive and unstructured features of flight test data, and the problems faced by pro cessing and application, on the basic research of the cloud technology, an application architecture of cloud technology for flight test data is presented, which composed of equipment system, cloud storage and cloud corn puting. The cloud storage based on use-frequency matrix is established according to flight subject and flight ma neuver about flight engineering objects. The cloud computing based on SOA with data processing functional modules is realized by usiBg the particular distributed task scheduler servers＇ group and the calculation serv ers＇ group, to serve for processing users with high effective and performance. The system with a flexible archi tecture can effectively provid the efficient storage, unified management, sharing application and the rapid pro cessing about the unstructured massive flight test data. The successful engineering application verifies the ad- vantages of the new cloud technology.
