Abstract (en)
[origin: EP2275743A2] The chamber has a starter film for cooling a combustion chamber wall (4). A combustion chamber head is limited towards a combustion chamber by a heat shield (5), where cooling air is introduced in to the head. A base plate (2) is arranged at a distance from the heat shield and includes openings (6) in a rim area for passing the cooling air. Center axes (17) of the openings are inclined at a shallow angle (alpha) relative to the combustion chamber wall. A cooling airflow (3) is conducted via the openings in a direction of flow onto a deflection area.
