Supplemental dataset for the paper "Estimating aircraft drag polar using open flight surveillance data and a stochastic total energy model"

This dataset contains the dataset for the paper "Estimating aircraft drag polar using open flight surveillance data and a stochastic total energy model". <br><br><b>Dataset structure:</b><br><i>flight_trajectories</i>: Contains flight trajectories generated from ADS-B and Mode S data. Trajectories are sorted by aircraft types and sorted in different subdirectories.<i><br></i><i>estimation_results</i><b>: </b>Contains the drag polar parameters estimated by the method proposed in the paper. The estimations are based on previous trajectories.<br><i><br></i><i>cfd_simulation_results</i>: Contains CFD simulation results of a B747-400 aircraft with different angles of attack and corresponding lift/drag coefficients.<br><b><br></b><b><br></b><b>CSV column definitions:</b><br><i>ts</i>: Unix time stamp<i>icao</i>: aircraft ICAO Mode-S transponder identifier<i>lat</i>: latitude (deg)<i>lon</i>: longitude (deg)<i>alt</i>: altitude (ft)<i>gs</i>: ground speed (kt)<i>trk</i>: track angle (deg)<i>roc</i>: rate of climb (ft/min)<i>tas</i>: true airspeed (kt)<i>ias</i>: indicated airspeed (kt)<i>mach</i>: Mach number<i>wx</i>: wind speed at x axis (u component of wind) (m/s)<i>wy</i>: wind speed at y axis (v component of wind) (m/s)<i>temp</i>: temperature (K)<i>cd</i>: drag coefficient<i>cl</i>: lift coefficient<i>cd0</i>: zero lift drag coefficient<i>k</i>: lift induced drag coefficient<i>e</i>: Oswald factor<i>m</i>: mass (kg)<br>
