A sealing system is described for effecting a seal of a gap (G; G) in a turbomachine () between a first structural member () and a second structural member (). The sealing system includes a sealing apparatus comprising a sealing member () comprising a first edge portion () and a second edge portion (). The two edge portions are parallel to one another and the first edge portion () forms a pivoting connection to the first structural member (). The first structural member () further comprises a seat () rotatably housing the first edge portion () of the sealing member (). The second edge portion () comprises a curved contact surface (), in sealing contact with a contact surface () of the second structural member (). Further disclosed herein is a gas turbine engine () with a combustor liner () and a sealing arrangement to seal a gap (G; G) between the combustor liner () and the turbine nozzles of the first turbine stage.
