To improve the reliability and stability of inflatable wings, In this paper, a method for enhancing the stiffness of existing inflatable wings is proposed by utilizing the light-curing properties of epoxy resins. The wings are made of glass fibers impregnated with epoxy resin, which are cured under ultraviolet light to improve the strength and stiffness of the aerated wing. Further modeling and simulation analysis of the aerated wing are carried out to verify whether the mechanical properties meet the requirements. The analysis results show that the light-cured wing can maintain its basic shape without internal pressure, and the modal frequency has a significant increase. The comparison between the data and the experimental data shows that the maximum displacement of the wing is reduced by 90.26% on average under the action of concentrated force load, and the maximum displacement of the wing under the action of uniform force load is reduced by 86.7% on average.
