• Blowout is a severe problem for engines and one of the major concerns in the power and aviation industry.
• The lean fuel-air mixture in combustion engines where the number of air molecules per molecule is high and causes a significant reduction of the flame temperature inside a combustor near the reactant flame due to the pressure reduction of the flame temperature inside. Such lean conditions make an engine susceptible.
• The invention addresses, the lean flame blowout (LFO) problem which leads to unplanned power outages and can increase operational costs.

• The invention will predict the exact time to blowout in a combustor, which can be several seconds in advance.
• The core of this technology is that, instead of producing another warning method about an impending blowout, it predicts the time of its occurrence without using any user defined threshold values.
• It performs the prediction by fitting a log-periodic power law curve (LPPL) to the experimentally obtained time series data of an appropriate variable such as (but not limited to) fluctuating pressure or heat release rate.
• The observed variable data can be acoustic pressure fluctuations which are measured using a pressure transducer such as a microphone or a piezoelectric transducer but not limited to it, or heat release rate obtained from a photomultiplier or camera.
