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

48th 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.

Thermoacoustic instabilities: Modeling and control

IEEE Transactions on Control Systems Technology, 2003
The goal of this study was twofold. First, modeling strategies were proposed to characterize the dynamics driving the thermoacoustic instabilities in a swirl-stabilized premixed burner. Second, this model was used to synthesize controllers in order to apply active control strategies to suppress this phenomenon.

Adaptive control for thermoacoustic combustion instabilities

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
Thermoacoustic instabilities in combustion processes involve pressure and velocity limit cycling oscillations that can have adverse effects on system performance. Using a nonlinear state space model for combustion processes that captures the coupling between unsteady combustion and acoustics, a direct adaptive control framework is used to design high ...
