Bird impacts pose serious threats to military and civilian aircrafts as they lead to fatal structural damage to critical aircraft components.The exposed aircraft components such as windshields, radomes, leading edges, engine structure and blades are more vulnerable to bird strikes.As per airworthiness regulations, the critical components must be capable of withstanding these strikes and aircraft must land safely after the bird strike.Windshield is the frontal part of cockpit and more susceptible to bird impact.The windshield design must satisfy the federal aviation regulation which demands that windshield must have sufficient perforation resistance and enough visibility for safe flight continuation and landing after the bird impact.In the present study, Finite Element (FE) simulations were performed to access the dynamic response of windshield against the high velocity bird impact.The numerical simulations were performed by developing a detailed nonlinear FE model in commercially available explicit FE code.The numerical model was validated with the published experimental results.Investigations were carried out to evaluate the influence of various parameters on impact behavior of windshield.The parameters include the mass, shape and velocity of bird, angle of impact, impact location, thickness variation and curvature angle of windshield.On the basis of numerical results, the critical bird velocity and critical impact location on windshield were also determined.The results show that these parameters have strong influence on the impact response of windshield.The parametric study of these factors will help to optimize the design of windshields against bird impact threats.
