DEVICE FOR CHECKING EFFICIENCY OF ANTI-ICING METHODS Russian patent published in 2025 - IPC F03D80/40 G01M9/06 

FIELD: experimental aerodynamics.

SUBSTANCE: invention relates to experimental aerodynamics, in particular to climatic wind tunnels, and can be used to study the efficiency of anti-icing systems. Device for checking the effectiveness of anti-icing methods (100) comprises cold air flow forming device (10), water supply system (37), spraying nozzle (39), refrigerating unit (40), optically transparent working chamber (50) with a device for changing the angular position of test object (51), optical measuring system (60) and control module (70). Water supply system (37) is connected by first pipeline (35) to spraying nozzle (39). Optical measuring system (60) is optically interfaced with working chamber (50). Control module (70) is connected by common bus (79) with cold air flow forming device (10), water supply system (37), refrigerating unit (40) and optical measuring system (60). Cold air flow forming device (10) comprises parallel connected at least first (11), second (12), third (13) and fourth (14) Ranque-Hilsch tubes, the cold outlet of which is connected to horizontally located ventilation channel (99) with square cross section, in which honeycomb (20) is made, designed to level the field of air flow and reduce the level of turbulence in working chamber (50). Refrigerating unit (40) is connected by the second system of pipelines (41) to test object (51). Working chamber (50) comprises diagnostics module (59) connected to said control module (70). Working chamber (50) is equipped with technical connectors for connection of external additional equipment. Measurements of the formed ice on test experimental object (51) are carried out by optical measuring system (60) using a phase triangulation method.

EFFECT: providing the possibility of measuring efficiency of anti-icing effects by optical methods.
