METHOD OF ANTI-ICE TREATMENT OF AIRCRAFT SURFACES AND MOBILE UNIT FOR REALIZATION OF THIS METHOD Russian patent published in 2003 - IPC

FIELD: spraying transport facilities. SUBSTANCE: proposed unit mounted on truck 1 includes reservoir 2, pipe line 4 with nozzle 5 for delivery of anti-icing fluid 3 to aircraft surfaces. Truck 1 carries hoisting mechanism 6 with operator's cab 7 and autonomous power source 8 (diesel-generator) with high-pressure apparatus 9 for delivery of anti- icing fluid to nozzles 5 via pipe lines 4. Reservoir is provided with two electric heaters 11 and 12 with inlet branch pipes 13 and outlet branch pipes 14. Reservoir 2 is simultaneously connected with apparatus 9 by means of pipe line 15 and is provided with level indicator 16. Electric heaters 11 and 12 are mounted under bottom 17 of reservoir 2 used for storage of anti-icing fluid 3; inlet branch pipes 13 of electric heaters are connected with reservoir 2 by means of pipe unions 18 fitted in lower portion 19 of lateral surface of reservoir 2 and outlet branch pipes 14 are connected with reservoir 2 by means of pipe unions 20 fitted in upper portion 21 of lateral surface of reservoir 2; these branch pipes are heat- insulated. Prior to treatment of aircraft surfaces, anti-icing fluid is heated to temperature of 60 C by means of electric heaters 11 and 12. Preheated anti-icing fluid is fed to working chamber at a pressure of 4 bars by means of sprayer with nozzle 5. EFFECT: reduced labor consumption; low cost of method. 9 cl, 1 dwg
