A series of wind tunnel tests were conducted to develop a boundary-layer tripping technique and also a detection technique for the boundary-layer state in transonic wind tunnels in ISTA/JAXA. A commonly used disk-type roughness element was used in the test and the conventional criterion for the effective roughness height was confirmed valid in the present case, also. A detection methodology for the boundary-layer state based on the quantitative measurement of the aerodynamic heating was applied to this experiment in a blow-down transonic facility, using both the Temperature Sensitive Paint (TSP) technique and the Infra-Red Thermograpy (IR) technique. The results indicate the methods are both useful in transonic experiments. Transition detection in a closed-circuit transonic wind tunnel was also achieved by varying the reservoir temperature, but it is found that the technique is not necessarily good for the boundary-layer state determination without any additional roughness for the reference purpose.
