Abstract (en)

[origin: EP1593913A1] The chamber has inner annular and outer annular walls (4a, 4b) united by a transverse wall (4c). The annular walls are extended at their downstream ends by inner and outer fastener flanges fastened respectively to inner and outer shells of a casing. The inner flange has a set of air feed holes to feed cooling air to a high pressure turbine. The holes are distributed circumferentially over two rows in a staggered configuration.
