The impact of discrete source damage on the dynamic characteristics of composite blades is a design factor explicitly required by airworthiness regulations. Advisory circular indicate that experiment-piece-level simulation and experimental results can be used to demonstrate compliance with airworthiness regulations for structures. Against the backdrop of blade airworthiness certification requirements, this paper systematically investigates engineering simulation techniques for discrete source damage and the impact patterns of penetrating damage on the dynamic characteristics of composite laminates. Vibration experiments are designed to verify the accuracy of the analysis results. The research findings of this paper can provide technical support for the engineering application and airworthiness verification of composite blades.
