1. A gas turbine engine, comprising:
an engine core configured to generate a redline exhaust gas temperature (EGT) in a range of 988 degrees Celsius (C) to 1120° C., the engine core extending along an engine centerline and including:
a compressor section;
a combustor; and
a turbine section, the turbine section including a blade assembly rotatable about the engine centerline, the blade assembly including:
a platform having an upper surface and a lower surface, the platform having a stator rotor seal with an upper edge having a radius of curvature defined as a stator rotor seal radius (SRSR), wherein the stator rotor seal radius (SRSR) is 0.224 to 0.239 meters;
an airfoil coupled to the upper surface of the platform, the airfoil having an outer wall defining an exterior surface, the exterior surface defining a pressure side and a suction side, the outer wall extending between a leading-edge and a trailing-edge;
a shank coupled to the lower surface, the shank having a base defining a base plane; and
a plurality of cooling conduits located within the airfoil, the plurality of cooling conduits including:
a first cooling conduit located closest to the trailing-edge and defining a trailing-edge area (TEA), wherein the trailing-edge area (TEA) is from 0.0000056 square-meters (m2) to 0.00001 m2; and
a second cooling conduit next to the first cooling conduit and defining a secondary area (SA), wherein the secondary area (SA) is from 0.000002 m2 to 0.0000048 m2, and wherein,
