The supersonic wind tunnel at JAXA has been improved in FY1999 by replacing the nozzle section, extending the settling chamber and renewing the control unit. Through the improvement, total pressure is stabilized within 5 seconds and thereafter kept +/- 0.10 percent around the target pressure from M(sub infinity) = 1.4 to 4.0. The flow in the test section is highly two-dimensional both horizontally and vertically. Total pressure distribution in the test section settles within 2 percent of the each average values at M(sub infinity) = 1.4 to 4.0. Furthermore, one-man-operation had been made possible by this upgrade.
