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.

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 ...

A UK startup has unveiled a new fusion-powered space rocket concept called Sunbird for interplanetary travel to Mars — and ...

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 ...

This airframe will be the first to successfully carry a hybrid rocket engine developed at CU Boulder, and as such, will employ custom-designed avionics and a dual-deploy recovery system to not just ...

For decades, engineers have fought to prevent detonations in rocket engines—now, NASA is using them on purpose. The Rotating ...

Team Abstract: The HADES team is seeking to add to the collective CU Boulder knowledge base of hybrid rockets through the development of a liquid-solid hybrid engine. This engine will be used to power ...

Will Edwards is the co-founder and CEO of Firehawk Aerospace, a hybrid rocket engine design and manufacturing firm. Firehawk’s rocket engines are powered by their patented 3D printed rocket fuel.

Gilmour’s main hybrid rocket engine, Sirius, will power the first and second stages of the Eris rocket to orbit. Four Sirius hybrid rocket motors will power the first stage. A single Sirius ...

It is a hybrid between a conventional jet engine, and a rocket system powered by liquid oxygen. The system will be reusable, much like an aeroplane, with no need to jettison expensive fuel tanks ...

During the test runs at the facility at DLR's Trauen site, the catalytically decomposed hydrogen peroxide entered the combustion chamber at approximately 650 degrees Celsius. The heat released was ...
