Integrated lifing analysis of a film-cooled turbine blade

A method to predict gas turbine component life based on engine performance analysis is demonstrated on a hot section gas turbine component. The mechanical and thermal loading of the first stage high pressure turbine rotor blade of the FlOO-PW-220 engine, one of the most severely loaded components in the engine, is analyzed and a life assessment...

Analysis of combined convective and film cooling on an existing turbine blade

To support gas turbine operators, NLR is developing capabilities for life assessment of hot engine components. As a typical example the first rotor blades of the high pressure (HP) turbine of the FlOO- PW-220 military turbofan will be discussed. For these blades tools have been developed to derive the blade temperature history from flight data...
