In order to study the cooling characteristics of film-effusion combination cooling structure, three kinds of test pieces are designed. Their cooling effectiveness is investigated by experimental method with infrared cameras. The experimental result shows that: (1)the cooling film from the film slot improves cooling effect in the beginning region of the effusion cooling, which largely increases the integrated film-effusion cooling effectiveness, (2)the cooling effectiveness is gradually decreased with the increase of the effusion hole space, (3)the effusion hole angle has a large effect on the cooling effectiveness, and the cooling effectiveness is the highest when the effusion hole angle is 45°. But, at a higher blowing ratio, the cooling effectiveness reaches the highest in the mid and tail of the effusion cooling region with the effusion hole angle of 0°.
