REGULATION OF PRODUCTIVITY OF THE FAN BY CHANGE OF PARAMETERS BLADE SYSTEMS
In this paper the system of productivity air's regulation by using of adaptive blade's systems of axial ventilator is offered. Preconditions for creation adaptive blade system were the detailed analysis of problems of the elasticity theory, in particular deformations of a plate, a core and a profile. In an offered construction of directional, straightening blades and fan impeller are executed flexible plates. It provides shock-free entry of stream on blades of the driving wheel directing and straightening devices. Minimization of hydraulic losses, optimum work on variable modes, raises efficiency of ventilating system in a wide range of change of productivity.
