Gas turbine engine nose cone

摘要

A gas turbine engine nose cone ( 44 ) comprises a spinner ( 46 ) and a fairing ( 48 ). The spinner ( 46 ) has a conical upstream portion ( 50 ) and a cylindrical base portion ( 52 ). The fairing ( 48 ) is frustoconical and surrounds the base portion ( 52 ) of the spinner ( 46 ). The outer surface ( 68 ) of the fairing ( 48 ) forms a continuation of the outer surface ( 56 ) of the conical upstream portion ( 50 ) of the spinner ( 46 ). A fibrous material ( 86 ) extends around the upstream end ( 82 ) of the fairing ( 48 ). The outer surface ( 68 ) of the fairing ( 48 ) has a skin ( 80 ) to protect the fairing ( 48 ) from erosion. The skin ( 80 ) extends around the upstream end ( 82 ) of the fairing ( 48 ) and is infiltrated into the fibrous material ( 86 ) to form a composite material and to bond the skin ( 80 ) to the upstream end ( 82 ) of the fairing ( 48 ).
