Aerodynamic fairings secondarily attached to nosecone

摘要

An aerodynamic fan nosecone for a gas turbine engine is provided and includes a fan nosecone that may be made of composite material. To improve airflow transition to the blade members, aerodynamic fairings are provided and are secured to an exterior surface of the nosecone which enhances fuel economy. The fairings may be secured to the nosecone by various methods, including providing for the fairings to be changed out and replaced with other fairings on the same nosecone assembly.

主权项

1. A one-piece aerodynamic fan nosecone assembly comprising:
a fan nosecone having a leading edge and a trailing edge with an aerodynamic exterior surface extending between the leading and trailing edge; a plurality of aerodynamic fairings spaced apart and affixed to said aerodynamic exterior surface of the fan nosecone, at least one of the fairings including: a base having an aerodynamic portion, and an attachment feature that mounts an underside of the base to the fan nosecone; and an insert having a portion projecting from the base that enhances aerodynamic sealing between the fan nosecone and a blade member, wherein the insert includes a filler material.
