Beschreibung
Zusammenfassung:	The internal wall (30) or external wall has a set of cooling holes (44), each being inclined at an inclination angle with respect to a normal to the wall. The holes are distributed according to a set of axially spaced lines from/to each other to allow air to circulate from a cold side of the wall to penetrate on a hot side, in order to form a film of cooling air along the wall. Geometric drilling axes of each of the holes are directed according to a direction of air flow (F2) circulating around the wall in order to maintain supply of air axially across the holes along the wall. An independent claim is also included for a combustion chamber.
