The turbine section consists of a gas producer turbine support, a power turbine support,
an exhaust collector support, a two-stage gas producer turbine, and a two-stage power
turbine. The gas producer, power turbine, and exhaust collector supports are high
temperature resistant structures which house support and thrust bearings, oil and air
seals, passages for lubrication, cooling air and thrust balance air, temperature sensing
thermocouples, and the outer casings which connect the combustion section and the
accessory gearbox. The two turbine units are free to revolve independently of one
another. Each turbine stage consists of a stator, or nozzle (stationary guide vanes
which direct the combustion gases) and a rotor, or turbine wheel (which is reaction
driven by the combustion gases).
