Abstract: Bird-strike failure of fan blades is one of the basic challenges for the safety of aircraft engines. Simplified slender blade-like plates are always used to evaluate the impact-induced damage mechanism at design stage. One undesirable issue is the failure at the root of clamped slender plates, which cannot recover the real case of twisted blades. For this purpose, three different strategies were exploited to obtain desirable deformation and stress responses, namely the impact location, additional weight, and t… Show more

“…The “leaf root” mentioned in this paper refers to the root area of the aero‐engine blade, as shown in Figure 8 in the Regulation ROI blue box area. It is believed that the root of the leaf occupies about 10% of the length of the entire leaf, and the deformation here is the smallest 40–42 . At the same time, the first 5 detection points in the Registration ROI of the blue area of the root are selected for tracking and positioning.…”

“…The authors et al [8] previously considered the bird-strike failure analysis of rotating laminated disks, where the rotation effect was addressed for future applications of the aeroengine system. Then, the authors et al [9] also studied the impact responses of simplified blade-like composite plates. However, the impact damage was not evaluated therein.…”
