For the full-height honeycomb sandwich airfoil of composite panel,the finite element model of the airfoil was created based on MSC.Patran/Nastran.The structure under uniform load was simulated and analyzed.The results show that maximum displacement of the structure is 2.79 mm,and the flexural load is 33.7 kN.At the same time,the structural flexural strain 1 308.6 με is calculated by engineering method.The maximum displacement of the measured airfoil in the static strength test is 2.81 mm. The theoretical and experimental methods are combined to analyze the airfoil of the sandwich structure.The maximum displacement value deviation is about 0.7%,which proves the rationality of the simulation analysis model and provides a reference for the engineering application of this type of structure.
