• Assessment of Uncertainty in Aerospace Propulsion System Design and Simulation 

      Mavris, Dimitri N.; Roth, Bryce Alexander (Georgia Institute of Technology, 2003-12)
      The subject of uncertainty analysis in complex systems design is a broad and bourgeoning field of study. This paper focuses on only three very specific areas of current propulsion research wherein uncertainty plays a ...
    • Creep Life Uncertainty Assessment of a Gas Turbine Airfoil 

      Wallace, Jon Michael; Mavris, Dimitri N. (Georgia Institute of Technology, 2003-04)
      Hot gas path turbine components are exposed to very severe and complex boundary conditions and many other sources of variation during their design, production, and operation. Consequently, the useful life of these components ...
    • A Method for Modeling System-Driven Uncertainty during Probabilistic Part Life Analyses 

      Wallace, Jon Michael; Volovoi, Vitali V.; Mavris, Dimitri N. (Georgia Institute of Technology, 2004-11)
      Probabilistic part life analyses of turbine components have typically been conducted in an ad-hoc fashion with respect to the influence of the system. While this approach greatly simplifes the analysis, signifcant errors ...
