ABSTRACT:
In a combustion chamber, the hot gases are prepared sequentially via two stages (20, 40). Arranged at the end of the first stage (20) in the direction of flow is a cross-sectional constriction (30) via which the hot gases (21) prepared in the first stage (20) are passed over into the second stage (40). The Mach number at the outlet (31) of this cross-sectional constriction (30) corresponds to the area ratio of outlet area (A2) over inlet area (A1). This results in a low-reflection configuration in which low-frequency vibrations are absorbed to a significant extent. And acoustic energy reflected from the turbine is substantially reduced.
