Thrust reverser cascade with one or more flow stabilizers

An apparatus for an aircraft propulsion system, comprising:

• a propulsion system structure including a flowpath and a thrust reverser system;
• the flowpath extending within the propulsion system structure to an exhaust nozzle;
• the thrust reverser system comprising a thrust reverser cascade;
• the thrust reverser cascade extending longitudinally between a cascade forward end and a cascade aft end, the thrust reverser cascade extending laterally between a cascade first side and a cascade second side, and the thrust reverser cascade extending radially between a cascade inner face and a cascade outer face;
• the thrust reverser cascade including a plurality of vanes and a wall;
• the plurality of vanes distributed longitudinally along the cascade inner face, and the plurality of vanes including a first vane and a second vane longitudinally aft of the first vane;
• and
• the wall longitudinally between and connected to the first vane and the second vane;
• and
• the plurality of vanes exposed to the flowpath when the thrust reverser system is stowed.

• the thrust reverser cascade including a plurality of channels arranged in a longitudinally extending array, each of the plurality of channels extending radially through the thrust reverser cascade from the cascade inner face to the cascade outer face, and the plurality of channels including a first channel, a second channel and a third channel;
• the second channel longitudinally between and neighboring the first channel and the third channel, and a longitudinal distance between the first channel and the second channel different than a longitudinal distance between the second channel and the third channel;
• the thrust reverser cascade further including a first vane, a second vane and a wall longitudinally between and connected to the first vane and the second vane, the first vane forming a side of the first channel, the second vane forming a side of the second channel, and the wall arranged at the cascade inner face;
• wherein the first vane and the second vane are exposed to the flowpath when the thrust reverser system is stowed.
