XLR-11 Rocket Engine



The X-1 was powered by a four-chamber, XLR-11 rocket engine, fueled by a mixture of liquid oxygen and diluted ethyl alcohol.

Although not throttleable, the chambers could be fired individually or in groups to produce a maximum rated thrust of 6000 lbs. at sea level.

Fuel capacity limited full-power of the engine to about five minutes.
