John revisited the assumptions around rockets and will use hot hydrogen fuel to enable air-breathing hypersonic rockets to be simplified. An air-breathing rocket can increase the payload capacity from ...

SABRE, on the other hand, is a hybrid air-breathing rocket engine. During the atmospheric segment of its ascent, it will use oxygen from the atmosphere instead of carrying it inside the vehicle, ...

While a conventional rocket engine must carry giant tanks of fuel and oxidizer on its journey to space, an air-breathing rocket motor pulls most of its oxidizer directly from the atmosphere.

Turborocket that combines air breathing rocket and jet engine could be next step after Spacex reusable rockets. April 7, 2017 February 15, 2016 by Brian Wang. A new type of engine combines the speed ...

What differentiates an air-breathing rocket from a typical jet engine is its scope of use. The style of jet engine used in most aircraft ceases to function at speeds in excess of Mach 3 or 4, at ...

Read a blog by spacecraft engineer Henry Spencer arguing that rockets, not air-breathing planes, will be the spaceships of the future. Getting to space has never been simple. A standing army of ...

UK company Reaction Engines is developing its Synergetic Air-Breathing Rocket Engine (SABRE), which could fly in space at Mach 25 and cut UK-Australia flight times to ‘as little as four hours’ ...

173 jobs gone after air-breathing rocket project loses lift Updated Aerospace specialist Reaction Engines has gone into administration, potentially taking with it the dreams of hypersonic aircraft ...

Kratos’ CEO Eric DeMarco disclosed the development of a new internally funded hypersonic drone, with a focus on affordability and possibly using air breathing propulsion technologies.

Rocket-powered vehicles were developed for two primary purposes: spaceflight and weaponry. Guided missiles also appeared in the mid-twentieth century with air-breathing propulsion systems, and these ...

The fastest aircraft ever flown, NASA’s X-43, used a rocket engine to provide an initial boost before an air-breathing hypersonic jet engine—known as a scramjet—took over and accelerated the ...
