N2 - This paper presents a novel shape optimization design method for blended-wing-body underwater gliders (BWBUGs), where a geometric parameterization method is proposed to generate design variables and the lift-to-drag ratio of the BWBUG is maximized. In this strategy, the shape parameters of BWBUGs are divided into section shape parameters and plane shape parameters. Then an efficient Kriging-based constrained optimization method (SCGOSR) is employed to optimize the two different shape parameters and the performance of these parameters in the two parts are further analyzed. The results show that the lift-to-drag ratio of the optimized BWBUG has been increased by 4.4226% and 2.4564%, respectively. Obviously the cross-sectional shape parameters have a greater impact on the performance of the BWBUGs.
