This new generation fibre laser source designed and developed at ONERA allows the Licorne platform to measure the windspeed in real time at a rate of 10 Hz and a spatial resolution of 150 m. Rapid airspeed fluctuations are detected... Windspeed measurements with the Licorne platform. The figures show the windspeed as a function of the distance
The campaign was aimed at validating the performance, over a 10 km radius, of a new windspeed and turbulence mapping lidar in an airport environment. This lidar consists of a new high power fibre laser source developed by ONERA and integrated into the scanning Windcube ® of the company Leosphere (see photo)
Objective: to improve their performances in all windspeeds and also to build even more powerful wind turbines... However, the aerodynamics of wind turbines are very different from those of helicopters: wind turbines rotate at low speed, which means that they are more sensible to atmospheric turbulence
