Correlation Analysis of Aircraft State Parameters Based on Telemetry Data

The telemetry data reflects the state of aircraft. It is of great significance for state interpretation, abnormal state detection and applause analysis to deeply analyze and find the correlation between parameters in telemetry data. The flight state of the aircraft is divided into motion state, environmental state and equipment working state according to the physical information reflected by telemetry data. In this paper, the correlation coefficient calculation method is designed, which combines the PRE (proportional reduction of error) method and the distance correlation method. On this basis, a typical flight data of long-endurance aircraft is selected. The correlation coefficient of two parameters is calculated by the design method. The correlation between different types of parameters is given. Among them, this paper focuses on the analysis of the correlation between irradiation intensity and pitch angle, solar array output current and aircraft surface temperature, solar array output current and pitch angle.
