Systems and methods for detection of blowout precursors in combustors

A method for detecting blowout precursors in combustors comprising:

• receiving pressure data measured by an acoustic pressure device associated with the combustor;
• performing spectral analysis on the pressure data using Fourier transform analysis;
• performing statistical analysis on the pressure data using statistical moments;
• performing wavelet analysis on the pressure data using wavelet transform analysis;
• and
• determining the existence of a blowout precursor based on one or more of the spectral analysis, statistical analysis, and wavelet analysis.
