Why Rockets and Turbines Scream: Thermoacoustic Instability

Rocket engines and gas turbines can develop destructive pressure oscillations when unsteady heat release couples with acoustic waves. This is thermoacoustic instability: combustion feeds sound, sound reshapes combustion, and the loop can grow into damaging vibration, noise, and hardware failure. Engineers analyze the Rayleigh criterion, chamber modes, injectors, damping devices, baffles, liners, and testing data to keep engines stable.
