Unmanned Aerial Vehicle (UAV)-borne gas detection and measurement can drastically reduce operational risks for the involved first responders in scenarios where hazardous gases may be present, e.g. accidents in industrial plants or gas leaks/accumulations in urban settings. However, measurement accuracy and detection abilities of gas sensors can be severely affected by the UAV’s rotor downwash, thus leading to erroneously low gas-concentration readings. We have investigated the applicability and operational parameters of probing tubes extending from under the UAV to escape downwash effects and thereby improve measurement results.
