Finding the cause of a fatal problem in rocket engine combustors

A vital piece of gas engines, combustors -- the chambers in which the combustion powering the engine occurs -- have the problem of breaking down due to fatal high-frequency oscillations during the combustion process. Now, through advanced time-series analyses based on complex systems, researchers have found what causes them, opening up novel paths to solving the problem.
