1. A rotor containment structure for a rotor, the rotor containment structure comprising:
a shroud coaxial with and partially surrounding the rotor, the shroud comprising:
a tubular section extending axially past a first side of the rotor;
a transition section connected to the tubular section and adjacent to a curved side of the rotor; and
a flange section connected to the transition section opposite the tubular section and extending radially past a radially outer side of the rotor; and
a shroud reinforcement enclosing the transition section of the shroud, the shroud reinforcement comprising:
a support scaffold comprised of a series of geometric retaining features encircling a radially outer surface of the transition section, wherein the geometric retaining features are spaced axially along the shroud; and
a reinforcing material coupled to the support scaffold to restrict radial expansion of the shroud,
wherein the reinforcing material is between the geometric retaining features of the support scaffold, and
wherein the geometric retaining features extend from parallel to an axis of the shaft, and wrap around the shroud reinforcement into a perpendicular orientation relative to the axis of the shaft, and the reinforcing material extend from parallel to an axis of the shaft, and wrap around the shroud reinforcement into a perpendicular orientation relative to the axis of the shaft.
