Multi-ply heat shield assembly with integral band clamp for a gas turbine engine

A gas turbine engine comprising:

• a first case segment with a first flange;
• a second case segment with a second flange and a third flange, a first interface defined by the second flange and the first flange;
• a first multiple of bolts that extend through the first interface;
• a third case segment with a fourth flange, a second interface defined by the fourth flange and the third flange;
• a second multiple of bolts that extend through the second interface;
• a heat shield assembly that extends at least partially around the first multiple of bolts and the second multiple of bolts, wherein the heat shield assembly comprises:
• a first heat shield ply assembly defined about an axis;
• a second heat shield ply assembly defined about the axis, the second heat shield ply assembly receivable at least partially over the first heat shield assembly;
• and
• a band clamp mounted to the second heat shield assembly to circumferentially retain the first heat shield ply assembly and the second heat shield ply assembly.
