Systems and methods for brake whirl mitigation

A method comprising:

• fabricating a torque tube having a circumference, a first axial portion, a second axial portion, and a back leg disposed closer to the first axial portion than the second axial portion;
• and
• fabricating a plurality of first circumferentially disposed splines extending from the back leg towards the second axial portion;
• fabricating a plurality of second circumferentially disposed splines, wherein the second circumferentially disposed spline is not in contact with the back leg,
• wherein each of the plurality of first circumferentially disposed splines is disposed asymmetrically about the diameter relative to each of the plurality of second circumferentially disposed splines, and
• wherein the first plurality of circumferentially disposed splines and the second plurality of circumferentially disposed splines comprise an entirety of circumferentially disposed splines on the torque tube.

An apparatus comprising:

• a torque tube having a diameter, an outer surface, a first axial end and a second axial end;
• a back leg at a first axial end of the brake disk stack, and
• a plurality of first stiffening members coupled to the back leg and the outer surface;
• a plurality of second stiffening members disposed on the outer surface,
• wherein each of the plurality of first stiffening members is disposed asymmetrically about the diameter relative to each of the plurality of second stiffening members, and
• wherein the plurality of first stiffening members and the plurality of second stiffening members comprise an entirety of stiffening members on the torque tube.
