Which risk increases when continuously throttling a cryogenic rocket engine?

💡 Explanation

Combustion instability may result from throttling because the reduced mass flow rate decreases the damping of acoustic oscillations inside the combustion chamber impacting stable deflagration; therefore instability grows rather than reaching equilibrium at a different operating pressure.
