An important component to protect an airplane and its passengers from engine-blade fails is blade containment. This feature will stop the blade fragments to intrude the protected zone and the fragments must go to the unprotected zone. This paper presents a finite element (FE) analysis of aero-engine protection with various types of sandwich construction. The FE model was validated by available experiment data, then a parametric study of the sandwich structures against a blade-off is evaluated. The evaluated sandwich constructions are aluminum foam sandwich (AFS), blast resistance adaptive sandwich (BRAS), and auxetic honeycomb sandwich (AHS). The result shows that the auxetic honeycomb sandwich (AHS) has better deformation reduction and specific energy absorption than the other sandwich constructions.
