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.

Engineers developed an engine prototype which could reach unprecedented speeds, cutting down interplanetary travel time.

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 ...

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 ...

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 ...

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.

Most liquid-fuel rocket engines require a secondary combustion chamber to which some fuel is diverted; the exhaust gas is shot through a turbine to pump fuel and oxygen into the main chamber.

The Apollo 11 astronauts used advanced technology to land on the Moon. The Saturn V rocket was the largest rocket ever at that point — although SpaceX's Starship topped it when it took flight in ...
