THRUST REVERSER FAN RAMP WITH NOISE SUPPRESSION

摘要

A fan ramp for use in a thrust reverser portion of a nacelle is disclosed. The nacelle is included in a propulsion system. The fan ramp extends circumferentially about an axial fan ramp centerline. The fan ramp includes a forward edge, an aft edge, and a noise suppression feature. The forward edge is disposed proximate an aft end of a fan case. The fan case at least partially surrounds a fan section of a gas turbine engine. The aft edge is disposed proximate a forward end of an array of cascades. The array of cascades is operable to permit a bypass airstream to pass there through during a thrust reversing operation. The noise suppression feature is operable to suppress noise within the propulsion system.

1. A fan ramp for use in a thrust reverser portion of a nacelle, the nacelle being included in a propulsion system, the fan ramp extending circumferentially about an axial fan ramp centerline, the fan ramp comprising:
a forward edge disposed proximate an aft end of a fan case, the fan case at least partially surrounding a fan section of a gas turbine engine; an aft edge disposed proximate a forward end of an array of cascades, the array of cascades being operable to permit a bypass airstream to pass there through during a thrust reversing operation; and a noise suppression feature operable to suppress noise within the propulsion system.
