摘要
Flight tests of domestically produced large civil aircraft generate massive volumes of high-frequency time-series parameters, which are characterized by large data volume, numerous parameter channels, and highly customized analysis requirements. The conventional analysis paradigm based on "data files plus custom scripts" suffers from low efficiency, scattered algorithms, and poor reusability. This paper proposes a flight test data analysis method centered on built-in functions of a time-series database, which pushes computation down to the data storage layer, thereby establishing an in-database analytics paradigm in which data never leaves the storage layer. Based on a unified operator programming paradigm, analysis algorithms are encapsulated as registerable and parameterizable built-in functions, and an analysis function library covering 12 functional families is constructed. Furthermore, a layered data service and an operator-chain orchestration workflow are designed to enable direct output of analysis reports. Validation on real flight test data demonstrates that the proposed method reduces the full analysis time for a single sortie from the order of minutes to the order of seconds, and supports one-click analysis of long-term monitoring indicators across more than two thousand sorties, significantly improving both analysis efficiency and algorithm reusability.
