Thermoacoustic Instability in Solid Rocket Motor: Non-Normality and Nonlinear Instabilities [PDF]

open access: yes48th AIAA Aerospace Sciences Meeting Including the New Horizons Forum and Aerospace Exposition, 2010
An analytical framework is developed to understand and predict the thermoacoustic instability in solid rocket motors, taking into account the non-orthogonality of the eigenmodes of the unsteady coupled system. The coupled system comprises the dynamics of the acoustic field and the propellant burn rate.

Nonlinear saturation of the thermoacoustic instability [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2000
A weakly nonlinear theory of the thermoacoustic instability in gas-filled tubes is developed in the time domain by exploiting the difference between the instability time scale and the period of standing waves. By carrying the expansion to fourth order in the perturbation parameter, explicit results for the initial growth, nonlinear evolution, and final
