The aerodynamic characteristics of the NAL 50cm hypersonic wind tunnel were tested at Mach numbers of 5, 7 and 9 with respect to Mach number and total temperature profiles at the test section, the effect of Reynolds numbes on the free stream Mach number, and boundary layer thickness at the nozzle exit, etc. Force tests of AGARD standard models HB-1 and HB-2 were also performed and the results were compared with those of other tunnels.
From these tests, it is expected that the tunnel will be useful for applied and development research on the aerodynamics of hypersonic vehicles.
