Abstract

A numerical investigation is conducted on a rotating engine blade subjected to a bird strike impact. The bird strike is numerically modelled as a cylindrical gelatine with hemispherical ends to simulate impact on a rotating engine blade. Numerical modelling of a rotating engine blades has shown that bird strikes can severely damage an engine blade especially as the engine blade rotates as the rotation causes initial stresses on the root of the engine blade. This paper presents a numerical modelling of the engine blades subjected to bird strike with porosity changes implemented on the engine blades to investigate further damage assessment due to this porosity effect. As porosity has an effect on the decibel levels on a propeller blade or engine blade, the damage due to bird strikes can investigate the compromise this effect has on the structural integrity of the engine blades. The data is presented through variations of bird strike impact velocity and engine blade rotation as a function of porosity.
