Flow surveys have been made in the first of several nozzles to be investigated in an 11-inch hypersonic tunnel. The nozzle was designed by the method of characteristics for a Mach number of 6.98. Two 2-dimensional steps were used: the first step expanded the air in the horizontal plane to a Mach number of 4.36 and the second in the vertical plane to a Mach number of 6.98.
