| ABSTRACT This paper presents a part of study conducted to investigate the dynamic behavior of a rocket propellant rocket engine. The part presented here concerns the modeling, simulation and analysis of the dynamic behavior of the hydraulic control valves of the feeding system of the studied rocket engine. The study involves the combustion chamber, the gas generator controller, the thrust regulator, and the relief valve. For the studied valves, non-linear mathematical models have been deduced and used to develop computer simulation programs. The study was extended to investigate the static and dynamic behaviors of the valves. The study showed that the combustion chamber and gas generator controllers act to produce a feeding fuel pressure equal to the oxidizer pressure. The thrust controller, through regulating the combustion chamber pressure, could keep a fairly constant thrust of the rocket engine. The developed simulation programs could be used for further investigation of the effect of the valves constructional and operational parameters as well as the study of dynamic behavior of the liquid propellant engine. | ||||
