The invention discloses a wind tunnel fixed wing model surface pulsating pressure measuring method. The method comprises the following steps of: S1, shooting a dark background through a camera, erecting the camera and an excitation light source right above a to-be-measured pressure surface of the model, enabling a test site to be in a dark room environment, and shooting an environment dark background image through the camera; S2, turning on the excitation light source; S3, shooting a windless reference image through the camera; S4, making a wind tunnel to blow wind, starting the wind tunnel torun to a test wind speed and a test state, arranging the model is in a flow field, using pressure-sensitive paint for sensing pressure change of the surface of the model, and arranging the excitationlight source and the camera outside the flow field; S5, shooting an experiment image by the camera, and recording a pulsating pressure condition on the surface of the model; S6, conducting calculation and displaying an experiment result. The method has the advantages of simplicity and convenience in operation and use, high intelligent degree, high detection efficiency, good detection effect and the like.
本发明公开了一种风洞固定翼模型表面脉动压力测量方法，其步骤包括：步骤S1：通过相机拍摄暗背景；将相机和激励光源架设于模型待测压力面的正上方，试验现场处于暗室环境，通过相机拍摄环境暗背景图；步骤S2：打开激励光源；步骤S3：通过相机拍摄无风参考图像；步骤S4：风洞起风；风洞开车，运行至试验风速和试验状态；模型在流场内，利用压敏漆感受模型表面的压力发生变化，激励光源和相机在流场外；步骤S5：相机拍摄实验图像，记录模型表面脉动压力情况；步骤S6：计算、实验结果显示。本发明具有操作使用简便、智能化程度高、检测效率高、检测效果好等优点。
