Problems solved by technology

3) Multiple water supply pressure sources are used to independently supply water to spray bars of different heights, and the pressure of each spray bar is adjusted independently. The adjustment parameter is single, but the scale of the equipment is large, and the hardware deviation requirements of each adjustment equipment are high, so it is suitable for larger Dimensions of the icing wind tunnel
[0004] However, when the spray system is used in the laboratory to conduct the aircraft test icing test, due to the differences in the size of the test pieces and the assessment items, the traditional fixed water supply system takes a long time to adjust the water supply pressure, which is not conducive to short-term aircraft test icing test

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to an icing test water supply system and a water supply method for aircraft testing. Background technique [0002] Aircraft test The icing test is a ground test to study the icing shape, icing tolerance and anti-icing technology of the windward surface of different components and the external sensing part of the detection instrument when the aircraft is flying under icing meteorological conditions. The core component of icing meteorological conditions is the icing cloud and fog generating device. The icing cloud and fog generating device is generated by the nozzle array installed on the spray equipment in the spray section of the icing wind tunnel. The parameters of the icing cloud and fog are generated by adjusting the spray equipment. It is realized by the pressure and temperature of water supply and gas supply. [0003] The goal of the water supply pressure regulation o...
