Nonlinear rocket motor stability prediction: Limit amplitude, triggering, and mean pressure shift
GA Flandro, SR Fischbach, J Majdalani - Physics of Fluids, 2007 - pubs.aip.org
High-amplitude pressure oscillations in solid propellant rocket motor combustion chambers
display nonlinear effects including: 1 limit cycle behavior in which the fluctuations may dwell
for a considerable period of time near their peak amplitude, 2 elevated mean chamber
pressure DC shift, and 3 a triggering amplitude above which pulsing will cause an
apparently stable system to transition to violent oscillations. Along with the obvious
undesirable vibrations, these features constitute the most damaging impact of combustion …
