The turbopump.
Two preburners spin two independent turbopumps — one rich in oxygen, one rich in methane. Both feed the main combustion chamber at temperatures the metal should not, by any reasonable metric, survive.
- Oxidizer pump
- 21,000 rpm · 6,800 kW
- Fuel pump
- 33,000 rpm · 8,200 kW
- Mass flow

- Material
- SX300 superalloy · investment-cast
// 03SUB-ASSEMBLYCOMBUSTION CHAMBER
Three hundred bar.
Inside the chamber, methane and oxygen burn at 300 bar — three hundred times atmospheric. The walls survive because we machine regenerative cooling channels through the copper-alloy liner; cold fuel runs through the wall before it ever sees the flame.
- Chamber pressure
- 300 bar · 4,350 psi

- CuCrZr alloy · 0.8 mm wall

// 04SUB-ASSEMBLYNOZZLE BELL
Looking up the bell.
From below, the bell looks like a cathedral. Sea-level expansion ratio is set so the exit pressure matches atmospheric at lift-off — perfectly tuned, the exhaust column stands rigid as a column of glass.

- Throat diameter
- 0.412 m
- Expansion ratio
- 40 : 1 · vacuum: 80 : 1

- Bell construction
- Inconel 718 · spun + e-beam welded
- Throttle range
