摘要： A fan section includes a fan inlet case, fan bearing assembly, and an annular heatshield. The fan bearing assembly may be coupled to the fan inlet case and the annular heatshield may be mounted to the fan inlet case. In various embodiments, the annular heatshield is configured to reduce convective heat transfer from heated fluid to the fan bearing assembly.
