Claim 16:
17. A heat shield assembly comprising:
a carrier comprising metallic material and including a base and a load flange that extends outwardly away from the base, and
a heat-shield tile comprising material different than the carrier and arranged to cover the carrier to protect the carrier from high-temperature air surrounding the heat shield assembly, the heat-shield tile including an outer wall configured to be exposed to the high-temperature air and an attachment feature that extends inwardly toward the base of the carrier,
wherein the attachment feature included in the heat-shield tile is coupled with the base to cause the load flange to engage the outer wall and apply an outward force to the outer wall,
wherein the carrier further includes a cage coupled to the attachment feature, a fastener fixed to the cage and configured to extend through the base of the carrier, and a nut threadingly engaged with the fastener on a side of the base opposite the cage, and
wherein the cage includes a bottom wall fixed to the fastener, a first hook coupled to a first end of the bottom wall, and a second end coupled to an opposite second end of the bottom wall and spaced apart from the first hook to define a slot therebetween sized to receive the attachment feature.
