Improved Resistance to Engine Bird Ingestion.

Abstract

An analytical design method capable of quantitatively evaluating and ranking rotor blades for resistance to bird impact damage was investigated. This method was used to design blades having sufficient tolerance to meet the bird-ingestion requirements of FAR 33.77 for turbofan engines in the 6800 to 1600 lbf thrust class. The design procedure was also used for the preliminary design of a damage resistance boron/aluminum composite fan blade for the 6800 lbf thrust class engine. In addition, two protective devices designed to prevent an ingested bird from striking sensitive engine parts were presented. (Author)
