Cascade system and apparatus

1. 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.

2. The thrust reverser system of claim 1 , further comprising a translating sleeve comprising a non-uniform annularly shaped pocket, wherein the cascade is receivable within the non-uniform annularly shaped pocket in response to the translating sleeve assuming a stowed position.

3. The thrust reverser system of claim 1 , wherein the torque box has a substantially constant radius relative to the engine centerline.

4. The thrust reverser system of claim 1 , wherein the aft cascade ring has a variable radius relative to the engine centerline.
