Modeling and robust analysis of a liquid rocket engine [PDF]
36th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 2000 Stability and dynamic performance of liquid-propellant rocket engines (LPRE) are two of the fundamental issues in the enginevehicle integration process. This analysis requires the construction of a detailed model, trying to capture the most realistic phenomena involved, which generally include several sources of uncertainties.

Fundamental Concepts of Liquid-Propellant Rocket Engines
2020The engine of a rocket vehicle is a machine which produces thrust by accelerating a gas flowing through the machine. The reaction to this acceleration is the force which drives the vehicle. The amount of thrust generated depends on the mass flow rate of the gas moving through the engine and on the exit velocity of the gas from the nozzle. The gas flow,

Liquid-Propellant Rocket Engine Injector Dynamics
Journal of Propulsion and Power, 1998The dynamic characteristics of liquid-rocket injectors in the presence of intense combustion-chamber and propellant feed-line oscillations are discussed. Liquid-propellant injectors always function in nonsteady e ow environments and are therefore considered as a dynamic component of an engine.
