Maze composition cooling structure of combustor is a kind of novel cooling structure incorporated the strong points of impingement, convection heat exchange and approximately perspiration cooling. It possesses the advantages of impingement, convection heat exchange and mat wall cooling structure, so it is an ideal cooling structure. On the basis of investigating cooling mechanism of this cooling structure and from the practical point of view, tile maze cooling structure is designed by taking the modification design of combustor in active service engine for example. Meantime heat exchange analysis and calculation of wall temperature also are made. Preliminary investigation shows that the cooling performance of this cooling structure is superior to that of full air-film cooling structure.
