View up the exit plane of the bobtail thrust chamber.

Picture 1 of 2.

Note that the regenerative cooling tubes comprising the thrust chamber have just been cut; it would seem that no fuel flowed through them during the cold calibration testing. The cross-section of the tubes on this bobtail thrust chamber compares favorably with those at the throat of an actual thrust chamber.

When on-site, I failed to follow the flow of fuel from the turbopump, but it appears that the fuel high-pressure duct leads to the pipes on the lower right of the thrust chamber.
