Abstract
A device (20, 29, 48, 64) for cooling a supporting structure of a heat shield (33, 60) to avoid scaling of the supporting structure due to the intake of hot gas. The device has a longitudinal axis (21) and a cooling air duct (22). The device is on the supporting structure with the longitudinal axis (21) intersecting the surface (51) of the supporting structure (34). In this position, the cooling air duct (22) extends from a device end (23) pointing towards the supporting structure. The device has at least one outlet duct downstream in the cooling air duct. The duct emerges out of the device (20, 29, 48, 64) laterally with respect to the longitudinal axis (21). The cooling air duct (22) corresponds to at least one cooling air passage (50) in the supporting structure (34).
