摘      要：As a type of autonomous underwater vehicle(AUV),underwater gliders(UG)are getting increasing attention in ocean *** save energy and satisfy the mission requirements of a longer voyage,shape optimization for UGs has become a key technique and research *** this paper,a conventional UG,including its fuselage and hydrofoil,is optimized,which aims to decrease the average resistance in one motion *** operate the optimization progress for the complex object,multiple free form deformation(FFD)volumes are established for geometric ***-fidelity simulation models are employed for objective function evaluation and gradients *** sequential quadratic programming(SQP)method is adopted as an optimization *** optimization results show that there exists a UG with symmetrical and non-horizontal hydrofoils that has lower resistance.
