HAZARD2 project: airspeed and temperature measurements in jet engine blast

摘要

For ground airport operations, a dangerous area is defined behind the aircraft when engines are running. Measuring the temperature and airspeed in this area is needed to calibrate simulation models and adjust the danger area size to the real conditions. A heavy fixed on ground instrumentation was possible but an innovative solution has been chosen, based on Lidar technology for airspeed measurements and Bragg sensors on optical fibers for temperature measurements.
