Abstract

Gas turbine engines (20) include a rotating component (304) having a disc and defining an axis therethrough. A static component (302) is arranged axially adjacent to the rotating component (304) and includes a primary rub flange (320) that extends axially from the disc of the rotating component (304) toward the static component (302). The static component (302) includes an interfacing rub flange (324) extending axially from the static component (302) toward the rotating component (304) and is arranged radially adjacent to the primary rub flange (320). The primary rub flange (320) includes a primary rubbing surface (322) and the interfacing rub flange (324) includes an interfacing rubbing surface (326) with the primary rubbing surface (322) spaced from the interfacing rubbing surface (326) by a separation gap (328). The primary rub flange (320) is configured to deflect in the presence of a crack in the disc to close the separation gap (328) such that the primary rubbing surface (322) contacts the interfacing rubbing surface (326).
