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 ...

HICKAM will design and manufacture a modular, compact, and portable testing platform for characterizing hybrid rocket engines. The team will also manufacture two 300 lbf hybrid rocket motors to prove ...

A California-based company, SpinLaunch, is making waves with its innovative satellite launch system, drawing particular ...

Hybrid rocket engines are the focus of research at institutions and universities worldwide. Due to their inherent safety, they are well suited for university education. Their good performance, ...

A laboratory prototype of a plasma electric rocket engine based on a magnetic plasma accelerator has been produced by Rosatom ...

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 ...

Reaction Engines, which is developing a hybrid rocket engine aimed at enabling hypersonic travel, filed a notice of intention ...

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 ...

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 ...

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.
