摘要： A snow environment test apparatus includes an injector including a two-fluid nozzle, a temperature setting section for setting an indoor temperature, an air conditioner for cooling an inside of a test chamber, a temperature control section for controlling the air conditioner, a water flow rate setting section for setting a flow rate of water to be supplied to the injector, a water supply section for supplying water having a predetermined temperature to the injector, a snow quality selection section for selecting snow quality, a related information storage section that stores information in which a temperature in the test chamber, a flow rate of water to be supplied to the injector, a pressure of air to be supplied to the injector, and a snow quality are related with each other, and a pressure regulation section for regulating the pressure of the air to be supplied to the injector to a pressure obtained by using the information stored in the related information storage section.

摘要： A snow making apparatus includes: a snow making container having an inner space for snow making; a supply unit configured to supply fine snow or fine water droplets to the inner space; a catching unit configured to catch the fine snow or the fine snow formed of the water droplets; and a drive unit configured to move the catching unit toward a place where the fine snow is flying in the inner space. The catching unit is configured to be shaken thereby making snow caught by the catching unit fall off from the catching unit.

摘要： In a snow accretion test method, a snow accumulation step of accumulating snow on a specimen, and a snow accretion step of freezing snow accumulated on the specimen in a state where snow is not supplied to the specimen are performed. The snow accumulation step and the snow accretion step are repeatedly performed. In the snow accretion step, the ambient temperature of the specimen is adjusted to a temperature lower than the ambient temperature in the snow accumulation step.

摘要： A snow making apparatus includes a cylindrical body and a snow making nozzle that jets water droplets into the cylindrical body. The cylindrical body has a proximal end that is opened to a temperature environment where snow can be produced from water droplets jetted from the snow making nozzle. A distal end of the cylindrical body is connected to a pipe member communicating with a test chamber. The snow making nozzle is formed of a two-fluid nozzle. The pipe member communicates with a snowfall hood disposed in the test chamber and having a supply opening that allows snow to fall. The cylindrical body is disposed in an oblique posture so as to be lowered from a proximal end toward a distal end of the cylindrical body.

摘要： A snow environment test apparatus includes a first nozzle that injects water particles, a second nozzle that injects water particles smaller in size than the water particles from the first nozzle, an air conditioner that regulates a temperature in a test chamber to a set temperature, a state selection section that sets a state of snow to be caused to fall, and a flow rate regulation valve that regulates a ratio between quantities of water to be supplied to the first nozzle and to the second nozzle for obtaining the state of the snow set by the state selection section at the set temperature as a temperature at which a snow environment is obtained.
