A method for constructing a multi-fidelity reduced order model has been proposed, which can effectively improve modeling efficiency and reduce the cost of flutter analysis. The generalization of Mach number and angle of attack shows that this model has good generalization capability and can be applied to flutter simulation of aircraft.
