Description

technical field [0001] The invention relates to the technical field of aircraft complete machine testing, in particular to a snowfall environment simulation device and simulation method for aircraft complete machine test. Background technique [0002] Foreign aircraft climate and environment tests are generally carried out on the whole aircraft, including laboratory tests, ground tests and flight tests; since there are no laboratories and test simulation equipment for aircraft climate and environment tests in my country, the climate before flight The environmental test can only be carried out in the field waiting for suitable meteorological conditions, which makes the test period long and expensive; Full-scale aircraft snow test. [0003] In the case of indoor artificial snowfall technology such as ski resorts, ice is usually made first, then crushed into fine ice particles, and blown out directly by a fan; it is characterized by large snow flakes, dry snow, and long-lasting ...
