Zusammenfassung:A component (62) of a gas turbine engine includes a continuous hoop portion (66) extending at least partially around an engine central longitudinal axis (A) of the gas turbine engine and a bolting feature (68) extending from the hoop portion (66), configured for securing the component (62) to an adjacent component (64). The bolting feature (68) includes a circumferential arm (80) extending radially and circumferentially from the hoop portion (66). The circumferential arm (80) defines a radial gap (86) between the circumferential arm (80) and the hoop portion (66). The circumferential arm (80) includes a bolt opening (74) for installation of a bolt therethrough. A connecting leg (88) extends radially from the hoop portion (66) across the radial gap (86) toward the connecting arm. An arm interlocking feature (92) is located at the circumferential arm (80) and is configured to radially interlock with a complementary leg interlocking feature (90) of the connecting leg (88). The arm interlocking feature (92) and the leg interlocking feature (90) have a radial interconnect gap (94) therebetween in a free state.
