image001 N&R Engineering performed probabilistic structural analysis of a CMC combustor liner to estimate probabilities of failure of the liner under normal operating conditions. The probabilistic analysis included uncertainties in the material properties, geometry and loading. A CMC combustor liner, similar to the one analyzed, was later tested at NASA by GE. The results of the analysis showed very close agreement with the tested results.

Services Provided:

  • Survivability of the cumbustor liner in a jet engine under the actual operating conditions.
  • Estimated the risk of failure incorporating uncertainties in geometry and material variables.
