Abstract
Det beskrives en variabel skovlarm (48) med dobbelt retensjonsevne for å sikre at skovler i en gassturbinmotor (20) forblir forbundet til skovlarmen (48) selv under "surgebelastninger" eller en forhåndsbelastning på festeanordningen (112),. eller hele festeanordningen (112) tapes. Den variable skovlarm tilveiebringer videre en "surgesliss" (80) for å lette rotasjon av skovlen (42) selv når skovlen (42) opererer under "surgebetingelser" eller andre særlig høye trykkbetingelser.
