POWER SECTION ASSEMBLY

TM 55-2835-209-23 1-14 POWER SECTION ASSEMBLY a. The power section assembly is comprised of the integrated compressor, combustion and turbine section. The inte- grated compressor utilized a centrifugal impeller and dif- fuser to provide the com- pressed air for combustion and bleed air purposes. Com- pressed air is the compressor ing (1) and is the combustion to the bleed ai when bleed air lized. Fuel is into the combusti contained by assembly hous- directed into chamber (2) and r outlet port flow is uti- introduced on chamber by six fuel nozzles (3) and com- bined with compressed air, thus is ignited by the igniter plug assembly (4) creating the hot gas flow that drives the turbine. b. The turbine section (5) uti- lizes a turbine nozzle to in- crease the hot gas flow velocity and direct it against the blades of the turbine wheel. The hot gases transmit energy into the turbine wheel and are discharged rearward through the turbine wheel which in turn, drives the com- pressor and gearbox assembly shaft (6). 1-8
