Composite propellant combustion represents a critical area of research, combining the complexities of chemical kinetics, fluid dynamics, and material science to understand and predict the performance ...

For dual-mode rocket engines to be successful, a propellant must function in both combustion and electric propulsion systems. Researchers have now used a salt-based propellant that had already been ...

It may be tough to believe, but solid propellants have been used in rockets since at least the 13th century, beginning with the Chinese. Now, Purdue University researchers are exploring several ...

Researchers are developing a new type of rocket propellant made of a frozen mixture of water and "nanoscale aluminum" powder that is more environmentally friendly than conventional propellants and ...

Flames, smoke and a deafening noise accompanied the first firing test of Vega’s Zefiro 9 third-stage solid rocket motor. A first examination of the data indicates that everything went well at the test ...

In space flight, propellants based on hydrazines are used, among other things, as standard for attitude and control regulation in spacecraft. Like the oxidizer dinitrogen tetroxide (NTO) used for this ...

SpaceX’s Raptor engine and Blue Origin’s BE-4 engine are two key innovations in rocket propulsion, each with its unique design and performance characteristics. While the Raptor engine leverages ...

In smaller spacecraft such as CubeSat satellites, a salt-based monopropellant is showing promise. It can be used both in high-thrust chemical propulsion for fast time-sensitive maneuvers, and electric ...

Gelled propellants are produced from liquid propellants with the addition of gelling agents. They are solid at rest, for example in a tank, and become flowable under the influence of shear stress, as ...
