AIRCRAFT SYSTEMS AND METHODS

Abstract:

A system includes plural airfoils operably coupled with a rotatable member of an aircraft engine system. The rotatable member is configured to rotate about an axial centerline of the aircraft engine system. The system comprises a feature at one or more exterior locations of an aircraft body. The feature is shaped to alter a flow of air between the aircraft body and the airfoils. Altering the flow of air also one or more of reduces a local load on the airfoils, reduces a local angle of attack of the airfoils, or reduces a noise level that is generated by the aircraft engine system as the rotatable member rotates about the axial centerline of the aircraft engine system relative to the aircraft body not including the feature.
