Reaction Motors/Thiokol XLR11
Beginning in 1943,
Reaction Motors developed the XLR11 for the XS-1 (later X-1) supersonic
research aircraft. The LR11 used ethyl alcohol and LOX fed to 4 thrust
chambers. Chambers could be ignited separately or in any combination.
The earliest flight I can find for the XLR11 is on the XS-1 in 1946.
The U.S. Navy designation for this engine was the XLR8.
- XLR8-RM-6: 6,000 lb (26.7 kN)
- XLR11-RM-5: 6,000 lb (26.7 kg) thrust
- XLR11-RM-13: 8,000 lb (35.6 kg) thrust
- Liquid-fuel rocket
- Fuel: ethyl alcohol
- Oxidizer: liquid oxygen (LOX)
- Bell X-1
