采用温度敏感涂料（TSP）对高速旋转螺旋桨的层流-湍流边界层过渡进行了测量。TSP配方、实验设置、图像采集和处理程序在预测试中进行了评估。即使在9600 rpm的转速下也获得了高分辨率的螺旋桨图像。得到的温度图像清晰地显示了层流到湍流边界层转变引起的温度阶跃。在预试结果的基础上，在不来梅空客低速风洞BLSWT上进行了螺旋桨转速高达14400 rpm的风洞试验。风洞试验的TSP结果可视化了螺旋桨叶片上层流和湍流区域随螺旋桨速度的发展。
The laminar-to-turbulent boundary-layer transition on a high-speed rotating propeller was measured using Temperature-Sensitive Paint (TSP). The TSP formulation, the experimental set-up, the image acquisition, and processing procedure had been evaluated in a pretest. High resolution propeller images were obtained even at rotation speeds of 9600 rpm. Obtained temperature images clearly show the temperature steps due to the laminar-to-turbulent boundary layer transition. Based on the pretest results, a wind tunnel experiment was conducted in the low-speed wind-tunnel BLSWT of AIRBUS in Bremen at propeller rotation speeds up to 14400 rpm. The TSP results of the wind tunnel test visualized the development of laminar and turbulent regions on the propeller blade depending on propeller speed.
