Overall view of the interior of the thrust chamber.

At center is the silver injector, which would spray the propellants into the combustion chamber.

The thrust chamber is comprised of corrosion-resistant steel regenerative cooling tubes.

Midway down the thrust chamber, additional, half-length tubes are added to the thrust chamber at the fuel manifold. This is visible as the large "ring" formed where gaps are introduced between pairs of full-length tubes. Turbine exhaust gases enter the thrust chamber through these gaps.
