| 摘 要： | 为了测量补燃室火焰温度场,在直连式试车台上进行二维开窗式固体火箭冲压发动机试验,应用高速数字摄影仪对补燃室内的火焰进行拍摄。对所获得的火焰图像,根据基于彩色CCD图像的比色测温原理,求得补燃室火焰的投影温度场。结果表明这种方法简单可靠,测量精度也满足要求,可以用来对补燃室火焰温度场进行测量。

| Abstract: | In order to measure the temperature field of the flame in the secondary combustion chamber, a test was conducted on a direct-connect test bed for ducted rocket motor which consisted of a secondary combustion chamber with a window. A high-speed photography was used to collect the image data of the flame. Based on colorimetric temperature-measurement method, temperature field of secondary combustion chamber is calculated. The result shows this method is reasonable. |
