采用压敏喷涂技术（PSP）和粒子成像测速技术（PIV）对低雷诺数的高弧度薄翼型进行了实验测试。这些技术具有低侵入性和高空间分辨率的特点。应报告实验装置和结果的详细情况。实验研究的目的是获得有关压力分布和流场特性周围和下游的非常规翼型的详细信息。对压力场和速度场进行了综合计算，得到了所研究迎角范围内的翼型升力、阻力和气动力矩系数。在小型开路艾菲尔风洞中对二维翼型模型进行了测量。测试活动的特点是两个雷诺数（200.000和300.000），模型入射范围在- -5°和+15°（1°步长）之间。
An experimental test campaign has been performed by means of Pressure Sensitive Paint Technique (PSP) and Particle Image Velocimetry (PIV) on a thin high cambered airfoil at low Reynolds number. These techniques have been selected for their characteristics of lowintrusivity and high spatial resolution. Details of the experimental set-up and results shall be reported. Experimental investigation has been intended to get detailed information about the pressure distribution and the flow field characteristics around and downstream a nonconventional airfoil. Pressure and velocity fields have been integrated to obtain the airfoil lift, drag and aerodynamic moment coefficients in the investigated range of angles of attack. Measurements have been performed in a low-scale open circuit Eiffel type wind tunnel on a 2D wing profile model. The test campaign has been characterized by two Reynolds numbers (200.000 and 300.000) and a model incidence ranging between - -5° and +15° (1° step).
