FIELD: testing.
SUBSTANCE: invention relates to test benches. Test bench for model of liquid anti-icing system (AIS) of aircraft contains device of frame structure (1) for attachment of tested model (2) of aircraft surface, hydraulic accumulator (3) with reduction gear, control valve, emergency air pressure relief valve. Test bench is equipped with control shut-off devices (6) and control pressure gauges (7) installed in the common branch of main line (5) for supplying the anti-icing fluid and in the branches of the supply mains of upper (8) and lower (9) parts of the skin of the model of the unit. Test bench is also equipped with the aircraft model skin surface condition monitoring system.
EFFECT: possibility of determining the anti-icing fluid operating efficiency.
