TL;DR: In this paper, gradient cellular centresymmetric auxetic configurations are evaluated as potential cores for aeroengine fan blades, and optimized to reduce the dynamic response for the first three fundamental modes.
Abstract: In this study, gradient cellular centresymmetric auxetic configurations are evaluated as potential cores for aeroengine fan blades, and optimized to reduce the dynamic response for the first three fundamental modes. Auxetic (negative Poisson’s ratio) re-entrant cellular beams are modeled, manufactured, and tested to assess their natural frequencies and mode shapes. Gradient versions of these beams with a varying internal cell angle are then designed to be incorporated as fillers in a baseline fan blade model. The optimized configurations of the gradient core lead to a substantial decrease of the mass of the fan blade, reduction of the dynamic modal displacements, and a lowering of the first three natural frequencies within the admissible frequency bandwidth.

TL;DR: In this article, numerical and experimental techniques were used to investigate the effect of bird strike on different types of aircraft bubble windows with different geometries and materials, and the results from all techniques were found to be almost similar and in good agreement with the test data.
Abstract: This paper uses numerical and experimental techniques to investigate the effect of bird strike on different types of aircraft bubble windows with different geometries and materials. Three different methods, namely Lagrangian, Arbitrary Lagrangian Eulerian (ALE) and Smooth Particle Hydrodynamics (SPH) are used to simulate bird strike effects on different types of bubble windows during the impact phase. Simple tension tests are carried out on some samples to determine the behaviour of window material during impact while models reported in the literature are used for modelling the bird. First, a simple bubble window is studied numerically using the Lagrangian, ALE and SPH techniques and the results are compared with experimental data. The results from all techniques are found to be almost similar and in good agreement with the test data. This will give way to only ALE to be used for other case studies. Next, bird impacts on a two-layer bubble window with a Poly Vinyl Butyral (PVB) interlayer and a multi-wall...
