ABSTRACT	Main characnly the tunnel scale,but also daily operational cycles become approximately 2.5 times those of the existing tunnel.The operational conditions of the new led are as follows : stagnation conditions of To=600～1,200 K and Po=1～10MPa,Mach number=10, Re=3×105～4.5×106/m and a viscous parameter of V=M/Re=0.005～0.014.The operational conditions of teh NAL’s hypersonic wind tunnel system could cover the flight conditions of a winged space vehicle such as the Space Shuttle and the Japanese future unmanned winged reentry vehicle HOPE in M-Re and M-M/Re maps in its Mach number range of M=5～11.
