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 ...

there’s more than enough info on his site to try and recreate some of his experiments, but perhaps you should start here instead: How to Design, Build and Test Small Liquid-Fuel Rocket Engines.

Eco-friendly alternatives to fossil fuels are venturing beyond Earth—and into space.

An international team of engineers and space scientists has used a variety of assumptions, techniques, and math principles to ...

Rocket engine manufacturer Ursa Major is accelerating the development of its Draper engine. The startup is collaborating with US agencies and military contractors to make the engine available for use ...

and rocket engines from small thrusters to a gigantic F-1 motor from the Saturn V Moon rocket. National Air and Space Museum Rocket, Liquid Fuel, R.H. Goddard 1935, A-Series National Air and Space ...

He has no hope that liquid-fuel rocket engines (“a remarkable chemical processing plant”) will ever get spaceships into space. The trouble with liquid-fuel engines, says Ritchey, is their ...

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 ...

Their big trouble is that they are harder to control than liquid-fuel rockets, whose small combustion chambers ... tested only in an experimental rocket engine on the ground.

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 ...

"Since the beginning of the year, Energomash has been holding first trials of liquid-fuel RD-191M engine for heavy-class Angara-A5M rocket of the Amur space complex," it said. The engine is an ...
