THE OPERATION OF COMPLEX MECHANICAL SYSTEM IN MOTOR TRANSPORT

The paper considers the operation of the fan as heat pump. Proceeding from the analysis of general scheme of fan operation transformation factor is determined. In the process of fan blades interaction with the environment the following problems are considered: impact mechanism of separate molecules of air, emerging centrifugal forms and hydrodynamic forces, caused by Bernoulli law. It was established that the power, consumed by the fan, depends on rotation frequency not on cubic power in 3/2 power with further transition into linear coupling.
