LR-101 Engine Thrust Chamber Gallery


Overall walk-around of the LR-101 thrust chamber.

Picture 5 of 6.

The gear at right is the pitch sector gear. The longer tube 180° from the gear is the fuel inlet.

The vertical tube at right leading aft from the fuel inlet carries fuel to the fuel manifold on the engine's exit plane. The thrust chamber is double-walled, and the fuel travels between the two walls of the thrust chamber to the injector at the forward end, providing regenerative cooling to the engine to prevent the inner wall from melting.
