Emily Timko, featured in a Faces of NASA article, poses in the IRT (Icing Research Tunnel) where she works as a “cloud engineer”. She is a Mechanical Test Engineer and works to create unique water spray conditions that simulate icing clouds in the natural aircraft flight environment. Shown in the photo is a portion of the fan drive motor and fan blades that together drive the air through the wind tunnel.

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.

The Icing Research Tunnel (IRT) is the longest running, icing facility in the world and has been in operation since 1944. Most ice protection technologies in use today were largely developed at this facility. In this facility, natural icing conditions, such as the clouds being created here, are produced to test the effects of icing conditions on aircraft components such as wings tails and engine inlets.

In the center with their backs to the camera are the wind tunnel operators who control the wind speed and super cooled water flow. In the center right of the photo is the video recording system and the test engineers. On the right side the test section can be see though the wind and the TV screen shows the pray bars that create the icing cloud.
