While we’re reluctant to say it for fear of being misinterpreted, the new liquid fuel rocket engine being built by Copenhagen Suborbitals is one of the most impressive, daring, and nearly the ...

"Propellant gauging has long been a problem," Collicott said. "I am not saying by any means that this has the whole thing solved." The technique also might be used to help design satellite fuel tanks ...

This article was originally published with the title “ Liquid-Propellant Rocket Development ” in Scientific American Magazine Vol. 155 No. 2 (August 1936), p. 78 doi:10.1038 ...

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 ...

Researchers tested the 3D printing materials to ensure they wouldn’t react with the conductive liquid propellant. Compatibility is crucial to prevent corrosion or cracking. In testing ...

SpaceX's Starship launcher spun out of control minutes after liftoff Thursday, showering fiery debris over the Bahamas and dealing another setback to Elon Musk's rocket program after a failure under ...

The device also requires a complex hydraulic system to store and regulate the flow of liquid, efficiently shuttling propellant through microfluidic channels. The emitter array is composed of eight ...
