WebJan 19, 2024 · The paper presents a validation of the authors’ model of a bird-impactor for bird masses M B = 0.7–3.65 kg, bird impact velocities V B = 100–200 m/s and impact angles α = 30–90°. Validation was performed by computations of bird impact with an obstacle by using a bird-impactor model and comparing computational data with … WebThe loading behaviour of birds at impact was characterized, to develop design methods and criteria. Luo et al. [2] investigated the impact-induced damages on carbon/epoxy composite plates. A three-dimensional finite element model was used to analyse the impact incidents, considering the delamination between the layers and polymer matrix failure
Dynamic Loading on Turbofan Blades Due to Bird-Strike
WebAug 1, 2024 · In bird-strike experimental tests, the test pieces are crashed against gelatin birds at an impact velocity of 200 m/s. Dynamic strain gauges are used to record the crash history and the results are discussed. ... resulting in a deviation between the actual bird strike load and the simulation load. In addition, the homogeneous isotropic material ... WebJul 1, 2024 · The uncoupled method disregards the bird and treats the impact load as a known quantity to analyze the structural response.
