A burning instability is one of essential and difficult problems for liquid-propellant engines preventing to implement high-efficiency propulsion plants meant for various applications. This problem is especially difficult for a case of multiple-mode propulsion plant because of non-stationary nature of its characteristics. A technique is offered and discussed to analyze operation process for a propulsion plant with controlled thrust by means of detailed description for processes in combustion chambers as applies to propulsion plants with thermal hydrazine dissolution. The analysis is carried out mainly for low-frequency instability case.
