摘　　要：本文研究了测量喷气推进器火焰湍流速度的激光多普勒方法。与其它方法相比较,该方法是非接触的光学方法,具有明确的方向响应和高空间和时间分辨能力,可用于研究高温、高速和高湍流强度的复杂燃烧情况。In this paper, the laser doppler method to measure the turbulence velocity of the jet propeller has been researched. The results indicate that this method offers unique advantages in comparison with other methods, for example, non-contact optical measurement, well defined directional response, high spatial and temporal resolution etc.. The method can also be utilized under the more complex combustion situation such as high temperature, high speed and high turbulence velocity.
