This paper proposes an uncertainty multidisciplinary propagation analysis method for correlated high-dimensional data. We employ the Nataf transformation and MaxEnt method to handle correlations, and raise a warm-up strategy to accelerate computation. The solid engine case validates that the proposed method can quantify coupled-propagating uncertainties more accurately.
