Combustor Liner Durability Analysis
- Pratt and Whitney Aircraft, East Hartford, CT (United States). Commercial Products Div.
The results of the 18 month Combustor Liner Durability Analysis Program (NAS3-21836) performed by Pratt and Whitney Aircraft are presented. The objective of the program is to evaluate the use of advanced three-dimensional transient heat transfer and non-linear stress-strain analyses for modeling the cyclic thermomechanical response of a simulated combustor liner specimen. Cyclic life prediction technology for creep/fatigue interaction is evaluated for a variety of state-of-the-art tools for crack initiation and propagation. The sensitivity of the initiation models to a change in the operating conditions is also assessed.
