Abstract
A turbine engine construction comprising a support housing, a compressor, combustor and turbine expander contained within the support housing. The combustor includes a combustor housing defining an inner combustion chamber and an outer chamber between the combustor housing and the support housing. Compressed air from the compressor outlet is communicated to the combustion chamber into which fuel is injected and ignited so that the resulting combustion products expand through a turbine nozzle and into the turbine expander. The novelty of the present invention resides in the construction of a diffuser assembly integrated with both the turbine nozzle and combustor. The diffuser assembly comprises a plurality of diffuser tubes, each tube having one end open to and in registration with the compressed air outlet of the compressor. The other ends of the tubes are arranged in at least two discharge planes for the combustor to improve and increase induced mixing and swirl in the combustion chamber. Preferably, at least one set of diffuser tubes discharges compressed air within the mixing zone of the combustion chamber and at a predetermined axial angle with respect to the turbine engine axis to provide a more uniform temperature into and through the turbine nozzle. The angular discharge from this set of diffuser tubes enables the turbine nozzle to be unwrapped from the conventional axial direction thus reducing both the axial length of the combustor and also the aerodynamic loading on the turbine nozzle.
