Definitions

  • a gas turbine engine may be used to power various types of vehicles and systems.
  • a typical gas turbine engine includes a fan section, a compressor section, a combustor section, a turbine section, and an exhaust section.
  • the fan section induces air from the surrounding environment into the engine and accelerates a fraction of the air toward the compressor section.
  • the compressor section compresses the pressure of the air to a relatively high level and directs the air to the combustor section.
  • a steady stream of fuel is injected into the combustor section, and the injected fuel is ignited to significantly increase the energy of the compressed air.
  • the high-energy compressed air then flows into and through the turbine section, causing rotationally mounted turbine blades therein to rotate and generate energy.
  • the air exiting the turbine section is exhausted from the engine via the exhaust section, and the energy remaining in the exhaust air aids the thrust generated by the air flowing through a bypass plenum.
  • FIG. 4 is the portion of the exemplary deswirl assembly shown in FIG. 3 aft looking forward;
  • the diffuser 204 is coupled to the shroud 210 and is configured to decrease the velocity and increase the static pressure of air that is received therefrom.
  • any one of numerous conventional diffusers 204 suitable for operating with a centrifugal compressor may be employed.
  • the diffuser 204 includes an inlet 214, an outlet 216, and a flow path 218 that each communicates with the passage 212, and the flow path 218 is configured to direct the received air flow radially outwardly.
