Numerical evaluation of the performances of a multilayered

Abstract

The improvements made in the field of the research of composite materials led to the wide usage of composite materials, which, nowadays, tend to replace traditional metallic materials in engineering applications. In this paper, the performances of a landing gear, subjected to dynamic loadings and made of a multilayered honeycomb composite material are evaluated in comparison with traditional metallic materials using numerical simulation. The obtained values of mechanical stress for the hybrid landing gear design are lower compared to those for a landing gear made entirely of aluminium. The use of the multilayered honeycomb composite material decreases the values of the stresses, for the given load case. Also, reduction of the mass of the landing gear improves flight dinamics and increases manoeuvrability.
