Zusammenfassung:	In one aspect, the present disclosure is directed to a cooling circuit for a gas turbine engine. The cooling circuit includes a rotor blade having a connection portion and a rotor disc having a first axial side and a second axial side. The rotor disc defines a connection slot and a cooling passage extending between the first axial side and the second axial side. The connection slot receives the connection portion to couple the rotor blade to the rotor disc. Cooling air flows through the cooling passage.
