This paper intends to design a better double-ended coaxial rotor airfoil with lower time-average drag coefficient and higher time-average lift coefficient in particular condition considering unsteady reverse flow, based on efficient surrogate-based multi-objective method(SBMO) and high-fidelity computational fluid dynamic(CFD) analyses.
