Axial Turbine Aerodynamics for Aero-engines

Abstract

In aircraft engine, the main task for low pressure turbine (LP turbine, LPT) is to drive rotational components, for example the fan or booster stages. It also can be used as direct power output apparatus, which provides shaft power to drive a propeller, fan, or other lift or thrust equipment. In turboprop and turboshaft engine, LP turbine is also known as power turbine or free turbine. In the spatial position of the flow path, LP turbine locates behind the high pressure turbine (HP turbine, HPT). Between the HP turbine and LP turbine in the high bypass ratio (BPR) turbofan engines, there usually arranges the bearing freamework known as the inter-turbine ducts, and turbine rear frame (TRF) ducts which is connecting to outlet nozzle.
