More Information
Summary:Sealing arrangements and turbomachines are provided. A sealing arrangement includes a transition duct having an upstream end and a downstream end. The transition duct includes an aft frame that circumferentially surrounds the downstream end of the transition duct. A stage one nozzle is spaced apart from the aft frame and defines a gap therebetween. A sealing assembly extends across the gap and is magnetically coupled to both the aft frame and the stage one nozzle. The sealing assembly includes a first magnet coupled to the aft frame and a second magnet coupled to the stage one nozzle. The sealing assembly further includes a shell that is coupled to and at least partially surrounds the first magnet and the second magnet.
