Multipiece nose cone for open rotor propulsion system

Abstract

A propulsion system assembly includes an open propulsor rotor, an open guide vane structure and a nose cone. The open propulsor rotor is configured to rotate about an axis. The open guide vane structure is aft of the open propulsor rotor along the axis. The nose cone is forward of the open propulsor rotor along the axis. The nose cone includes a forward tip end, an aft base end, a stationary section and a rotating section. The aft base end is adjacent to the open propulsor rotor. The stationary section projects axially along the axis from a junction between the stationary section and the rotating section to the forward tip end. The rotating section projects axially along the axis from the junction between the stationary section and the rotating section to the aft base end. The rotating section is configured to rotate with the open propulsor rotor about the axis.
