Theoretical Study of Fragmenting Birds Caught in a Safety Net of an Aircraft Jet Engines

Abstract

This paper presents a methodology based on two different approaches that define the conditions under which birds caught in a safety net placed at the inlet of an air turbine engine will be isolated. This refers to the speed at which the bird is hit, the mesh size of the net, the diameter of the wire mesh, the resistance of the mesh to strength etc. These characteristics are defined using a case study. The case of placing several nets in a row and the conditions of complete fragmentation of birds in them are discussed. Recommendations for determining the parameters of such protective mechanisms are developed.
