| Abstract: | For it is hard to measure turbine blade surface temperature by using the radiation thermometry and scanning technology, this paper designs a 45° rotation and reflection surface scanning system to measure turbine blade surface temperature distribution. The relationship between turbine blade surface temperature distribution and the internal structure of the blade is analyzed by comparison with the blade reference structure. Experimental results show that the surface scanning system is simple and convenient, and it can effectively extracts turbine blade surface temperature distribution characteristics. |
