The Institute of Theoretical and Applied Mechanics (ITAM) SB RAS has launched a unique wind tunnel for scientific research on icing in aviation, according to Andrey Shmakov, a researcher at the institute.

The experiment works as follows: we turn on the engine, the air starts to circulate, then we turn on the cooling of the flow, wait for the temperature we want to achieve, and in the working section on the model, we get ice build-up.
The new installation allows studying the icing processes of aircraft in sub-zero temperatures. The main feature of the created tunnel is its compact size (360x50x1000 mm). This allows conducting research on small objects.
The wind tunnel is a closed steel loop. In it, the air is cooled to the required temperatures using a flow-through heat exchanger. In the tunnel, it is possible to study the movement of air at speeds from 5 to 50 meters per second, and the temperature during the modeling process can vary from room temperature to minus 35°C.
A model is placed in the working section, onto which water is injected. Depending on the speed, temperature, and dispersed phase of the water, scientists can conduct research and measure how much ice forms on the model in a certain amount of time.
Earlier www1.ru reported that TsAGI created a "Wing Console" stand for regional aviation aircraft.
