Reheater interface

A reheater to gas turbine interface comprising:

• a turbine exit diffuser comprising:
• an exhaust duct arranged to receive flow from a turbine;
• and
• a plurality of fingers extending axially downstream and radially away from the exhaust duct, each finger of the plurality being circumferentially spaced apart from an adjacent finger of the plurality,
• wherein the fingers are arranged to contact a reheater during attachment of the reheater to the turbine exit diffuser;
• and
• the reheater duct comprising:
• a reheater duct body arranged to allow a core gas flow therethrough and to separate the core gas flow from a bypass gas flow outside the reheater duct body;
• and
• a plurality of first leaves extending axially upstream from the reheater duct body, each first leaf being separated from an adjacent first leaf by a first slit that extends axially downstream from an upstream end of the first leaves,
• wherein the first leaves are arranged to abut an exhaust duct of a gas turbine engine to form a seal between the reheater duct body and the exhaust duct,
• wherein an axially upstream end of the reheater duct is received in or receives the exhaust duct such that the reheater duct and the exhaust duct form a sealed interface.
