In-Wing Pressure Measurements for Airspeed and Airflow Angle Estimation

Year: 2022
DOI: 10.3929/ethz-c-000788334

Hardware designs and datasets for in-wing differential pressure sensing on a small UAV (EasyGlider 4), covering wind tunnel and flight tests for airspeed and airflow angle estimation and deep stall/high angle-of-attack maneuvers. Preview imagery and PCB/STEP files to be rehosted with the dataset.

Dataset Description

• HDF5 logs for raw and calibrated data, each with wind tunnel and flight datasets
• Includes PX4-based navigation data (ulog), synchronized at 40 Hz with preliminary airspeed estimates
• Calibrated datasets provide airspeed, airflow angles, and current following the paper’s procedure
• Key fields include differential pressures, airspeed, angles of attack/sideslip, vehicle attitude, and PX4 state
• Example Python script for reading/plotting; MATLAB HDF5 tools also applicable

Hardware Designs

• Differential pressure module STEP files
• PCB designs as KiCAD projects
