Liquid rockets are prone to large amplitude oscillations, commonly referred to as
thermoacoustic instability. This phenomenon causes unavoidable developmental setbacks
and poses a stern challenge to accomplish the mission objectives. Thermoacoustic
instability arises due to the nonlinear interaction between the acoustic and the reactive flow
subsystems in the combustion chamber. In this paper, we adopt tools from dynamical
systems and complex systems theory to understand the dynamical transitions from a state of …
