Liquid Rocket Thrust Chamber and it's Design Parameters

Liquid rocket thrust chambers are used widely in military crafts and space crafts because of their high specific impulse and thrust management capability. Combustion of liquid propellants in combustion chambers produces required thrust for shooting and movement of rocket in space. A thrust chamber is formed from three main parts: injector, combustion chamber and nozzle. Although there is a lot of a paper in field of rheology, atomization and combustion of liquid propellant, but there is limited published research in the field of design of liquid thrust chamber. In this article, the combustion chamber and different parts of liquid rocket motor are presented, then different types of prevalent injectors and their important design parameters and also common various methods for cooling of liquid motors are expressed.
