IGF::OT::IGF THE PROPOSED WORK WILL DEVELOP A RELIABILITY ANALYSIS TOOL CONSISTENT WITH CONCEPTUAL-LEVEL DESIGN FOR CERAMIC MATRIX COMPOSITE (CMC) TURBINE BLADES AND VANES. THE ANALYSIS SOFTWARE WILL COMPRISE A SUITE OF PHYSICS-BASED DISCIPLINE SPECIFIC ANALYSIS CODE MODULES AND NASA'S FAST PROBABILITY INTEGRATOR (FPI). THE OBJECTIVE OF THIS ANALYSIS TOOL IS TO DEVELOP OPTIMAL MATERIAL PROPERTIES, INTERNAL AND EXTERNAL GEOMETRIES FOR A COOLED VANE/BLADE USING AEROTHERMAL, AND STRUCTURAL (INCLUDING CREEP) ANALYSES. STRUCTURAL CONSTRAINTS IN THE FORM OF ALLOWABLE MECHANICAL/THERMAL STRESSES AND MATERIAL CONSTRAINTS IN THE FORM OF MINIMUM WALL THICKNESS AND MINIMUM BEND RADIUS WILL BE APPLIED. THE STRUCTURAL STRESS ANALYSIS WILL BE AUGMENTED WITH A CREEP MODULE TO DETERMINE AN ESTIMATE FOR PART LIFE. THE SUGGESTED BENCHMARK SYSTEM PROBLEM IS A MULTI-DISCIPLINARY ANALYSIS OF A NASA C3X TURBINE VANE, 2 OR 3D VERSIONS OF THE DISCIPLINE SPECIFIC MODELS WILL BE TAKEN FROM THE OPEN LITERATURE AND IMPLEMENTED AS PLUG-IN MODULES FOR NASA'S OPEN MDAO FRAMEWORK. IT IS NOT THE INTENTION OF THIS PROGRAM TO DEVELOP NEW MDAO ARCHITECTURES, RATHER THE OPTIMIZATION DRIVERS BUILT INTO OPEN MDAO WILL BE USED.
