TURBINE SECTION
The gas producer turbines on the T5 5-L-11 engine are two-stage, axial-flow turbines coupled
together and mounted on the rear of the compressor rotor shaft. The gas producer turbine nozzles and
rotors are shown in figure 5.10.
The gas producer turbine blades are air-cooled hollow blades held in place on the disk by
pins. Ahead of the first and second stage rotors are the gas producer nozzles, which direct the hot gas
onto the turbine rotors. The power turbine assembly is shown in figure 5.11.
The power turbine is a two-stage, axial-flow turbine coupled together and mounted on the
power turbine shaft. The power shaft transmits power from the power turbines to the power output
shaft. Basically, the function of the power turbine is to extract velocity
