Abstract
In an annular combustion chamber (1), which essentially comprises a plenum (7) for receiving a compressor air flow, burners (100) placed inside the plenum (7), a combustion space (122) arranged downstream of the plenum (7), and a cooling-air-carrying duct (2, 3) encasing the combustion space (122) and leading into the plenum (7), injector systems (8, 9) are arranged in the region where the coolingair-carrying duct (2, 3) leads into the plenum (7). These injector systems (8, 9) in each case consist of a flow duct as a continuation of the cooling-air-carrying duct (2, 3) and of a number of openings (5a) which are arranged in the peripheral direction of this flow duct and through which acceleration air (5) flows into the cooling-air flow. The effect of a bodiless diffuser is thereby achieved, and the pressure losses which occur given a widening in cross section are minimized.
