Abstract
A retaining element (22, 54) for retaining a heat shield tile on a supporting structure: A fastening section (23) fastened to the supporting structure. A retaining section (24) having a retaining head (25), which engages an engagement device on the heat shield tile. The fastening section (23) top side (28) faces the cold side of the heat shield tile when the retaining section engages the heat shield tile. Scaling of the supporting structure due to the entry of hot gas can be avoided particularly effectively by means of the retaining element. At least one cooling-air passage (34, 55) arranged in the fastening section (23) has an inlet opening (35, 68) and at least one outlet opening (37, 38, 62) which is arranged in a lateral surface (32) and/or on the top side (28) of the fastening section. Cooling air, which enters the inlet opening (35, 68) and exits from the at least one outlet opening, can be conducted in a respective outflow direction (50, 51, 59, 63, 61) by the cooling-air passage, which outflow is parallel to the cold side and avoids impingement cooling of the heat shield tile. The fastening section is arranged on the supporting structure such that the cooling-air passage (34, 55) corresponds to at least one cooling-air channel (45) in the supporting structure.
