激光片光照明实验装置,在水洞、烟洞中作了一些试验。拍摄了速度在100毫米/秒,3.1米/秒、9米/秒情况下,模型周围流场不同截面的照片。图象比较清晰直观,具有独特的优点。初步试验虽然是在低速范围内进行的,但片光照明显示方法本身可与蒸汽屏法等相结合,在亚、跨、超声速范围亦能显示涡流等复杂流场。
Laser light illumination experimental device, made some experiments in water holes and smoke holes. Photographs of different sections of the flow field around the model were taken at velocities of 100 mm / s, 3.1 m / s and 9 m / s. The image is clear and intuitive, with unique advantages. Although the preliminary test was conducted at a low speed range, the tablet light display method itself can be combined with the vapor screen method and the like, and can display complex flow fields such as eddy currents in the sub-span and supersonic speeds.
