Probabilistic Thermal/Structural Analysis
N&R has performed many probabilistic thermal/structural analyses on a variety of aerospace components including Space Shuttle Main Engine turbopump blades and jet engine combustor liners, rotor blades, and rotor discs. We have also determined the probabilistic property distributions of newly developed composites based on the uncertainties in the constituent properties. The N&R staff has a comprehensive understanding of the fundamental structural analysis techniques as well as extensive experience in the application of commercial analysis codes such as ANSYS, NASTRAN, PATRAN, MARC, ABAQUS, and ADINA and NASA specialty codes such as NESSUS and NESTEM.
