飞行试验数据是完成新机定型、鉴定的主要依据,同时也是支撑航空科技发展的宝贵资料,具有数据量大、数据来源多、数据模式不统一等特点。传统的关系数据库、操作系统文件等数据管理手段在性能上难以满足飞行试验对数据处理的需求,且不利于试飞数据的保存和共享。本文通过对飞行试验数据特性的分析,基于HDF5定义了专门用于管理飞行试验数据的文件格式HDF-FTD,并完成了基于Python语言和h5py扩展库的编程接口开发工作。
Flight test data is the main basis for the completion of the new aircraft stereotypes, identification, but also support the development of aviation science and technology valuable information, with a large amount of data, data sources, data model is not uniform and so on. Traditional data management tools such as relational databases and operating system files are difficult to meet the data processing requirements of flight test in performance and are not conducive to the preservation and sharing of flight test data. Based on the analysis of the characteristics of flight test data, this paper defines HDF-FTD, a file format specifically designed to manage flight test data based on HDF5, and completes the programming interface development based on Python language and h5py extension library.
