METHOD AND DEVICE FOR SUPPRESSING FORMATION OF ICE ON STRUCTURES AT AIR INTAKE OF TURBOMACHINE Russian patent published in 2016 - IPC F02C7/47 

FIELD: turbo-machines.

SUBSTANCE: method for suppressing ice formation on surface of a turbomachine structure during its operation, comprises piezoelectrically converting mechanical vibratory energy of said structure into electrical energy. Converting generated electrical energy into thermal energy and conducting said thermal energy to at least a portion of structure. Transmitting part of piezoelectrically generated energy directly to other part of structure of turbine machine for conversion of transferred energy into thermal energy or to external energy supply system, configured for repeated transfer of energy to part of structure of turbine machine for conversion of transferred energy into thermal energy. Another invention of group relates to a device for implementing said method and includes a housing with inlet section, consisting of a funnel, rotor surrounded by housing, row of blades inlet distributor connected to housing, and row of rotating blades connected to rotor. Funnel and/or at least one blade of inlet distributor and/or at least one rotating blade are equipped with a piezoelectric element, electric circuit connected with said piezoelectric element, as well as a transmitter for transmitting part of piezoelectrically energy.

EFFECT: group of inventions simplifies device for suppressing ice formation on surface of turbine machine structure.
