Abstract

An acoustically treated bullnose fairing assembly for a thrust reverser of an aircraft, the thrust reverser having an outer fixed structure and a stowable blocker door. The bullnose fairing assembly includes a back sheet, a face sheet and a honeycomb structure positioned between the face sheet and the back sheet—these three items being bonded together and securely affixed to an outer fixed structure of the thrust reverser. The back sheet has a forward end and a back end. The face sheet has a forward portion and a back portion, the back portion being aft of a forward edge of the blocker door when the blocker door is stowed. The forward portion of the face sheet is perforated. The perforated forward portion of the face sheet cooperates with the honeycomb structure to maximize the acoustic performance of the thrust reverser.
