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.

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

Meanwhile, solid rocket engines are simple and cheap, but once you light them, they’re going full-bore until burnout. Hybrid rocket engines offer perks from both worlds, with simple solid fuel ...

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, ...

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 ...

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 ...

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

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 ...

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

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 ...
