Nose cone with air scoop for open rotor propulsion system

An assembly for an aircraft propulsion system, comprising:

• an open propulsor rotor configured to rotate about an axis;
• and
• a nose cone upstream of and configured to rotate with the open propulsor rotor, the nose cone including an exterior sidewall and a first slot, the exterior sidewall extending axially along the axis from a forward tip end of the nose cone to an aft base end of the nose cone that is adjacent the open propulsor rotor, the exterior sidewall extending circumferentially around the axis and radially tapering to the forward tip end of the nose cone, the first slot projecting through the exterior sidewall and fluidly coupling an environment external to the nose cone to an interior of the nose cone, and the first slot disposed at an intermediate location between the forward tip end of the nose cone and the aft base end of the nose cone;
• wherein the first slot is an annular slot and extends circumferentially about the axis;
• and
• wherein a forward portion of the exterior sidewall is structurally tied to an aft portion of the exterior sidewall by one or more internal supports;
• and
• wherein a portion of each of the one or more internal supports at the first slot is spaced from the exterior sidewall.

An assembly for an aircraft propulsion system, comprising:

• an open propulsor rotor configured to rotate about an axis;
• and
• a nose cone upstream of and configured to rotate with the open propulsor rotor, the nose cone including an exterior sidewall and a plurality of slots, the exterior sidewall extending axially along the axis from a forward tip end of the nose cone to an aft base end of the nose cone that is adjacent the open propulsor rotor, the exterior sidewall extending circumferentially around the axis and radially tapering to the forward tip end of the nose cone, each of the plurality of slots projecting through the exterior sidewall, and the plurality of slots arranged circumferentially about the axis in an array;
• wherein the plurality of slots have an elongated shape extending circumferentially about the axis.
