Abstract:
1. An aircraft system, comprising a cascade thrust reverser including: a fixed reverser ramp; a nozzle outer wall section at least partially aft of the fixed reverser ramp, the nozzle outer wall section being movable between a deployed position and a stowed position, the nozzle outer wall section including a forward portion with a radially inwardly facing inner surface having a leading edge section, wherein at least a segment of the inner surface of the forward portion is at least generally planar; and a blocker door coupled to the nozzle outer wall section, wherein in the stowed position of the nozzle outer wall section the blocker door is at least generally parallel to the inner surface, and in the deployed position of the nozzle outer wall section the blocker door is at least generally perpendicular to the inner surface; wherein in the stowed position of the nozzle outer wall section the fixed reverser ramp has a portion forward of and adjacent to the nozzle outer wall section, the portion of the fixed reverser ramp having a first slope; and wherein the forward portion of the nozzle outer wall section has a second slope aft of the leading edge section, the second slope being different than the first slope, and wherein the at least generally planar segment of the inner surface lies in a plane that intersects the reverser ramp.
