In order to experimentally study the cooling characteristics of different compound cooling configurations in reverse flow combustor, three kinds of compound cooling configurations are designed. The research results from the experimental study for the test pieces show that; (1) There is an obvious effect of the blowing ratio on the cooling effectiveness, the bigger the blowing ratio, the better the cooling effectiveness. (2) Different cooling configurations show different cooling characteristics in the different section of reverse flow combustor. (3) For the reverse flow combustor, the cooling effectiveness of impingement+reversed convection+film cooling configuration and impingement+cocurrent convection+film cooling configuration have a great change. However, the cooling effectiveness change of impingement+effusion configuration is smooth, which means the temperature of reverse flow combustor is more even than that of the other cooling configurations.
