abstract = "This study, based on the Sparse Approximation of Moment-Based Arbitrary Polynomial Chaos method, investigates the impact of the number of deviation sections considered on the aerodynamic performance of a compressor rotor. The results indicate that under near-stall conditions, the aerodynamic performance parameters derived from sample sets with multiple deviation sections exhibit a typical normal distribution. In contrast, under peak efficiency conditions, the isentropic efficiency shows a markedly right-skewed asymmetric distribution. For sample sets considering only a single deviation section, positive thickness deviations lead to a non-monotonic relationship between performance parameters and deviation magnitude. Furthermore, accounting for multiple deviation sections significantly suppresses fluctuations in performance parameters and effectively reduces the variation amplitude of the static pressure coefficient along the chordwise regions of the blade surface.",
