[57] ABSTRACT

A hot gas generator includes a combustion chamber the heated gases from which drives a turbine the com bustion chamber being provided with air/fuel mixture for burning therein by a compressor driven by the tur bine. A second compressor isprovided to supply dilu tion ?uid in the form of an air/fuel mixture. The dilu tion ?uid together with the heated gases leaving the combustion chamber are maintained at a speed which is higher than the ?ame speed and the combustion of the air/fuel mixture which constitutes the dilution ?uid takes place in a second combustion chamber which in cludes a divergent portion whereby the velocity of the gases isreduced below the ?ame speed.
