摘　　要：超燃冲压发动机热结构试验要求测量发动机特征长度在试验中的变化。针对超燃冲压发动机热结构试验特点,利用单目视觉方法对超燃冲压发动机模型在电弧加热直连式试验中的结构变形量进行了测量研究,结果表明,针对表面基本为平面的发动机结构,利用单目视觉方法可以有效测量其特征长度的变形量,测量结果与通过测量发动机温度的计算结果具有一致性。Characteristic lengths measurement was required in scramjet hot structure test. According to the features of the test, a monocular vision method was adopted to measure the deformations of the hot structure in arc-heated scramjet direct-connect test. The results show that deformation of characteristic length could be measured efficiently using monocular vision method for quasi-plane scramjet structure, and deformation measurement results were consistent with the calculated results using measured surface temperature.
