Abstract
An assembly is provided for a powerplant. This assembly includes a radial flow rotor, a rotor shroud and a shroud arrestor. The radial flow rotor is configured to rotate about an axis. The radial flow rotor includes a rotor base and a plurality of rotor blades arranged circumferentially around and connected to the rotor base. The rotor shroud circumscribes the radial flow rotor. The rotor shroud is disposed adjacent tips of the rotor blades. The shroud arrestor includes an arrestor body and an arrestor mount. The arrestor body is cantilevered from the arrestor mount and circumscribes the rotor shroud. The arrestor body projects longitudinally out from the arrestor mount to a distal end of the shroud arrestor. The distal end of the shroud arrestor is next to the rotor shroud and is spaced from the rotor shroud by an air gap.
