Sodium chloride or ammonia was dissolved in the water propellant of pulsed plasma thrusters to improve the performance. Pulsed plasma thrusters using liquid propellant utilize water as attractive alternative instead of Teflon. Water propellant enables the controlling propellant mass flow and leads high specific impulse. However, liquid propellant pulsed plasma thrusters have larger plasma resis...

This paper presents a dynamic model of the interior ballistics of an experimental liquid propellant-powered rifle. The liquid propellant-powered rifle described utilizes a mixture of Hydroxyl Ammonium Nitrate (HAN) and hydrocarbon fuel to replace gunpowder typically used in such firearms. The motivation for such a development is to discard the need for a shell casing whereby carrying only prope...

Liquid propellant rocket utilizes an engine that uses liquid as a propellant. In rockets, fuel and oxidizer are pumped into the combustion chamber, where they get mixed burned. hydrogen is mainly used fuel, oxygen oxidizer. Slosh can occur with propellants. acts tuned damper helps in reducing dynamic response of vehicle. baffles tanks intelligent control rules guidance system be to this. A pote...

The supercharger is intended for heating a fluid (gaseous helium or gaseous nitrogen) used the pressurization of fuel tanks oxidizer and propellant rocket engine. heated with generator gas downstream turbine. A increased channel surface roughness was made according to an additive technology. High one features producing parts by selective laser melting. article presents method calculating heat t...

This paper presents an extension of Bayesian networks (BN) applied to reliability analysis of an open gas generator cycle Liquid propellant engine (OGLE) of launch vehicles. There are several methods for system reliability analysis such as RBD, FTA, FMEA, Markov Chains, and etc. But for complex systems such as LV, they are not all efficiently applicable due to failure dependencies between compo...

Method of obtaining tangential holes in the shell a combustion chamber liquid-propellant rocket engine is presented this article. Advantages and disadvantages technologies for making small diameter are consired. The developed technology tooling made it possible to obtain designed swirl coolant flow veil belt shell. As result, material labor costs were reduced manufacture components.
