[Faculty] Fwd: [CSRC-SDSU COLLOQUIUM]: Selecting Experiments for Uncertainty Quantification and Design Optimization of Aircraft

[Jose Castillo]

DATE:  Friday, May 9th, 2014

TITLE:  Selecting Experiments for Uncertainty Quantification and Design
Optimization of Aircraft

TIME:  3:30 PM

LOCATION:  GMCS 214

SPEAKER:  Dr. Diane Villanueva. Research Engineer, Universal Technology
Corporation

The design of hyper-sonic air vehicles involves a complex interaction of
physics, which at this point is not yet well understood. Unlike in
traditional aircraft design, the cost of prototype building and testing
for hyper-sonic vehicles is unacceptably large, so there is a greater
dependency on computational models. However, the prohibitive computational
cost of high-fidelity, coupled, aerothermoelastic simulation and the
inability to fully duplicate these combined flight loads through ground
tests poses a significant challenge for assuring the needed confidence in
model predictions. This talk will cover some of the key motivations and
features of a robust uncertainty quantification framework, including
Bayesian model calibration and optimal experimental design for these
experiments. Additionally, it covers a methodology to trade-off structural
mass and the effect of future tests and redesign in reliability based
design optimization once such a framework is in place.
