and even hybrid rocket engines are becoming passé. We’ve never seen a liquid-fuel rocket build before, so that’s what this roundup evolved into. First up is [Robert Watzlavick], who has been ...

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 ...

On February 21, 1931, Germany launched its first liquid-fueled rocket … sort of. The rocket only made it about ten feet off the ground. To be fair, the rocket itself was only two feet tall ...

The rockets are expensive, whether they use liquid or solid fuel ... can push an airplane forward just as efficiently as a fuel-burning rocket, and much more cheaply. When electricity is used ...

This liquid rocket fuel becomes magnetised when near a magnetic field. So it dances and morphs when magnets are moved around it. It is called ferrofluid and it was invented by NASA's Steve Papell ...

Description: Project BLERP aims to design and construct a reusable liquid rocket engine and launch stand that can be ... nitrous oxide and a fuel still to be determined.

For nearly a year, SpaceX has been trying out something new: super-cooling the liquid oxygen (LOX) which is a key ingredient in rocket fuel. It's called deep-cryo LOX, and the idea has been around ...

An initial analysis suggested that the cause of the failure involved the newly developed liquid-fuel rocket motor, but other possible causes were being investigated, a report carried by state ...

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 ...

Thus, to produce rocket fuel, the oxygen would have to be separated ... out the oxygen and the third converting the oxygen to a liquid form. Taken together, they found the approach would require ...
