We are fascinated by the hybrid rocket engine which [Ben Krasnow] built and tested in his shop. It is actually using a hollow cylinder of acrylic as the fuel, with gaseous oxygen as an oxidizer.

Rocket hybrid propulsion market is rapidly expanding, driven by military advancements, growing space tourism, and innovative ...

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 ...

Moreover, it is difficult for the fuel & oxidizer to be mixed intimately, hybrid rockets tend to fail more frequently than liquids or solids. Like liquid rocket engines, hybrid rocket motors can ...
