Cascade system and apparatus

A thrust reverser system formed around an engine centerline, comprising:

• a torque box;
• an aft cascade ring disposed aft of the torque box;
• a cascade having a first vane set and a second vane set,
• the first vane set having a fore end connected to the torque box, an aft end disposed aft of the fore end at an axial position and a radial position with respect to the engine centerline, and a first axial length extending between the fore end and the aft end of the first vane set, the first vane set positioned at a constant radius from the engine centerline along the first axial length and
• the second vane set having an aft end connected to the aft cascade ring, a fore end disposed at the axial position and the radial position of the aft end of the first vane set, and a second axial length extending between the fore end and the aft end of the second vane set, the second vane set positioned at a variable radius, from the engine centerline to a radially inward side of the second vane set, along the second axial length and varies about a circumferential position relative to the engine centerline, the variable radius decreasing in value from the fore end of the second vane set to the aft end of the second vane set.
