Running fuel-rich is cool since the fuel won’t find extra oxidiser to burn.
Excess hot oxidiser on the other hand can often fuel. Like the combustion chamber wall.
- dotancohen 6y agoThis is the answer that the GP was looking for, but it's phrased funny. sitharus means that the excess oxygen will oxidize (burn) things other than methane if there is enough oxygen present at the temperatures and pressures found in a rocket engine combustion chamber. It will oxidize (burn) things that you wouldn't normally think of as "fuel", such as the copper in the metal alloys.
