Abstract In order to verify whether the structural strength of the composite wing of a four-seater electric aircraft meets the airworthiness requirements (CCAR 23-R3 airworthiness requirements for normal, practical, special effects and commuting aircraft), this paper have studied and analyzed the structural of the composite wing, include the layout and ply of the wing beam, rib, skin, leading edge and trailing edge, and the connection form of wing-wing, wing-fuselage. And the deformation and the strain distribution of the composite wing under the limited shear load were calculated by established the finite element model of the four-seater electric aircraft. Finally, the accuracy of the finite element analysis results have been verified by the static testing of the whole aircraft. The results show that the results of the finite element analysis and the static testing were in good agreement, and the structural design of the composite wing met the structural strength requirements of the airworthiness.
