Beschreibung
Zusammenfassung:	A seal assembly between a transition seal structure associated with a downstream end of a transition duct and a vane seal structure associated with an upstream end of a vane structure in a first row vane assembly of a gas turbine engine includes a seal structure. The seal structure includes inner and outer seal members, each having a radially extending first leg and an axially extending second leg that provide each seal member with an L or V-shape. The seal members are arranged in a nested relationship with one of the seal members being positioned between the first and second legs of the other seal member. The first and/or second legs of the inner and outer seal members is/are received in a corresponding slot defined at least in part by one of the transition seal structure and the vane seal structure.
