Abstract

The work of the wind power plant in the winter in countries with severe weather condition is fraught with very serious consequences. There are frequent multi-day snow storms (storms) that lead to skidding sleet exposed surfaces of the unit with the subsequent formation of a dense snow-ice shell. For large frost (20-35 degrees C) frozen bearings, resulting in wind power plant goes down up to destruction under the pressure of the wind. Therefore it is important to have the technology, its production, its experience to develop promising new wind power plants, including those able to work in adverse weather conditions. A simple and reliable measure is the thermal protection element rotating windmill.For studying of regularity of heat exchange in a cavity of the krylovy NASA 0021 profile with an air stream running on it at a rotary motion of the wind turbine theoretical basics of processes of heat exchange in a cavity were covered.
