  • A temperature measure system for the leading edge of the rotating turbine blade was established based on stroboscopic imaging technique and thermochromic liquid crystal, while the temperature field characteristics of the leading edge were studied under different rotational speeds. The experiment result showed that this system was workable, and presented enough resolution and accuracy; the film cooling efficiency of the leading edge decreased with the increasing rotation number, and the disequilibrium of the film cooling efficiency on the pressure and suction surfaces increased.
