cntTSP is a flow visualization technique that uses the carbon nano-tube (CNT) as a thinfilm heater for Temperature-Sensitive Paint (TSP). The cntTSP technique can measure the movement of the boundary-layer transition on a moving wing model dynamically. This study conducted a wind tunnel test applying cntTSP to a wing model with a pitch-sweep motion. The detected boundary-layer transition position had a constant difference compared to the position in a pitch-fixed condition. Furthermore, we investigated the effect of the parameters of TSP thickness (5 and 40 μm), sweep speed (0.25, 0.50, 1.00°/s), and the with or without of a screen layer, and found that the tested parameters were not related to the difference of the transition position.
