| Abstract: | The design features and characteristics of a cryogeic windtunnel first designed and built in China were described in the paper.It is a closed circuit wind tunnel driven by fan.The test medium is gasnitrogen.The tunnel has a 0.1m square test section ann operates over thepressure from 101.3kPa to 202.6kPa and the temperature from 79K to 320Kat Mach number from 0.04 to 0.40.The running time is half an hour.The shell of tunnel is fabricated with aluminium-alloy.The external lay-er is thermal insulator of fibreglass.The fan is driven by an alterna-ting current motor.The revolutional control is achieved by changingfrequencies. |
