摘要

The structural frame includes an annular outer shell 52, an annular inner central hub 54, and a plurality of circumferentially-spaced struts 56 extending between and connected to the outer shell and central hub. The annular outer shell includes a plurality of panels connected end-to-end with one another. Each panel has a curved configuration and the outer shell has a central axis. The curved configuration of each panel of the outer shell runs in the direction of the axis.
