Abstract
Arrangement of holes for forming a cooling film on a wall (50) which is subjected to a flow of hot gas. Two rows (1, 2) of holes (10, 20) are provided which are arranged adjacent to one another, the diameter (d1) of the upstream holes (10) being smaller than the diameter (d2) of the upstream holes (20). The number of upstream holes (10) is equal to or smaller than the number of downstream holes (20). The use of such an arrangement of holes achieves the formation of an extremely effective cooling film with a simultaneously small consumption of cooling air.
