Interior of the thrust chamber.

The white circle is where the extra tubes are added to the thrust chamber at the hydrogen inlet manifold.

Forward of this point, there are only 180 tubes comprising the thrust structure. At the hydrogen inlet, an additional 180 tubes are introduced into the thrust chamber wall, allowing for a larger diameter.
