Selected Recent Projects
Multidisciplinary Evaluation of an Over-Wing Nacelle Aircraft (Sponsor: FAA)
- Role: Co-Investigator
- Project overview: Led an investigation of over-wing nacelle (OWN) placement for a 150-pax aircraft based on the NASA common research model. The work compared an OWN with an under-wing nacelle (UWN) using CFD coupled with the NPSS engine cycle model. The optimization process showcased methods including Bayesian adaptive sampling and gradient-free active subspace methods for dimension reduction; it also placed heavy emphasis on estimating and tracking errors in MDAO.
Uncertainty Quantification for an Enhanced Multimission Radioisotope Thermoelectric Generator (Sponsor: NASA Jet Propulsion Laboratory)
- Role: Co-Investigator
- Project overview: Bayesian uncertainty quantification, reliability analysis, and life prediction performed for a radioisotope thermoelectric generator (RTG) for spacecraft.
MBSE for Overall Aircraft Design (Sponsor: Airbus)
- Role: Technical contributor
- Project overview: Investigated uncertainty quantification methods, surrogate modeling, and MDAO aspects within an overall project that addressed the link between model-based systems engineering (MBSE) and MDAO.
