Summary

Description

English: Test engineers clean the ice cloud detection probe in the Icing Research Tunnel in between test runs. Steam is used to melt the accumulated ice on the detection probe. The test engineers need to wear goggles to protect them from the laser light that the probe emits. The laser detects water content and ice particles in the cloud that the wind tunnel produces. This process is done to calibrate the tunnel for research by characterizing the cloud flow.
