Uncertainty　Quantification(UQ)is　essential　in　aerospace　systems　as　system　performance　is　high　sensitive　to　uncertainties　associated　with　physics,materi-als,environments,models,and　so　forth.While　recent　advancements　in　UQ　across　various　engineering　fields　have　introduced　new　research　directions,significant　challenges　persist　in　developing　methods　to　address　high-dimen-sional,strongly　coupled　uncertainties　and　sparse　experimental　data.UQ　has　emerged　as　an　important　issue　to　be　addressed　in　simulation-based　aerospace　design.
