| 摘 要： | 采用压敏漆在超声速风洞中测量三角翼模型气动载荷,得到了应用压敏漆测压与天平测力相结合获取的三角翼模型气动载荷对比实验结果。简述了压敏漆原理、标定、试验设置和数字图像数据处理方法。由于尺寸限制,模型没有开设测压孔。对三角翼模型进行了数值计算,对试验和计算得到的结果进行了比较分析。

| Abstract: | Experiments of pressure sensitive paint on delta wing in supersonic wind tunnel are presented.The pressure measurment results by pressure sensitive paint were compared with balance measurment results to get load on delta wing model.Physical principle of PSP,calibration,experiment setup and digital image processing methods are briefly described.As the model size is small,there are no pressure taps.The numerical solution to delta wing and comparison between PSP result and numerical solution result were made. |
