eliminating the fuel–oxidizer turbine interseal, which is a potential point of failure in more traditional engine designs[clarification needed]; lower pressures are required through the pumping system, increasing life span and further reducing risk of catastrophic failure; ability to increase the combustion-chamber pressure, thereby either increasing overall performance or "by using cooler gases, providing the same performance as a standard staged combustion engine but with much less stress on materials, thus significantly reducing material fatigue or [engine] weight".
