ABSTRACT	A small supersonic wind tunnel(The NAL 0.2m Supersonic Wind Tunnel)was built at the National Aerospace Laboratory,Japan in 1995.The test section is 0.2m×0.2m in cross section and 0.4m long.Mach number can be set to any value from 1.5 to 2.5 by its flexible plate nozzle.Total pressure can be up to 0.15MPa and total temperature is around 330K.This tunnel has two unique points.The main structure and compressor were designed to be available at cryogenic temperatures.The contraction ratio to the test section is about 28,and the boundary layer suction device is mounted at the contraction,in order to e
