Abstract:Flight test data is the core product of flight test, which has the characteristics of large number of parameters, large data volume, high information complexity, fast query response, etc. It supports the tasks of aircraft design, manufacturing, flight test and other operations. The flight test data query engine aims to provide PB-level multi-dimensional flight test data fast query service, deep analysis of flight test data characteristics, adopts the key technology of big data interactive query, based on flight test data processing and analysis platform, researches the storage and calculation separation technology and heterogeneous computing technology. Based on the flight test data processing and analysis platform, the flight test data query engine is designed with the functions of multi-source data aggregation, multi-dimensional information fine query, multi-layer data flexible drilling, multi-functional custom function integration, multi-class index data adaptive output, etc. The innovative flight test data query and visualization method is successfully applied in the flight test data management and analysis of a type of domestic civil aircraft, and serves It has been successfully applied in the flight test data management and analysis of a domestic civil aircraft, serving flight test engineers, aircraft designers and subject engineers, improving the flight test data management efficiency and flight test data application value.
