The injector received LOX through the dome manifold and injected it through the oxidizer posts into the combustion area of the thrust chamber, while fuel was received from the upper fuel manifold in the thrust chamber and injected through the fuel orifices which were concentric with the oxidizer orifices.

Following a malfunction in the central thrust chamber of the launch escape system during the Soyuz TMA-15 mission to the International space station, concerns have been raised by officials with NASA and Russian organizations, like the Machine Building Central Research Institute, about the quality control and reliability of Soyuz emergency systems.

The exact cause of the accident was never determined, presumably it was due to a fuel leak between the fuel tank and the rocket engine, possibly due to a loose connection in a fuel line or low fuel tank pressure allowing some of the burning fuel in the thrust chamber to leak back into the fuel tank.

After much misadventure, a massive increase in budgetary requirements, and engineering problems related to fuel injectors and the thrust chamber which resulted in the Navy enlisting the assistance of the Rocketdyne Division of North American Aviation, the XLR30 engine project was moved back on track with a new designation of TR-139 to convey the striking changes in design which were required.

The thrust chamber injector received the propellants under pressure from the turbopumps, then mixed them in a manner that produced the most efficient combustion . 614 hollow oxidizer posts were machined to form an integral part of the injector, with fuel nozzles ( each swaged to the face of the injector ) threaded through and installed over the oxidizer posts in concentric rings.
