Sabre would work like an air-breathing jet engine from standstill to about Mach 5.5 (5.5 times the speed of sound) and then transition to a rocket mode at high altitude, going at 25 times the ...

A British company developing a rocket engine that can combust using oxygen from the air, as opposed to carrying liquid oxygen like traditional rockets, says it's passed a "significant milestone ...

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 ...

For example, the rocket design will be mastered from the design lessons and innovations of the rockets of historical importance. The more in depth analysis of the alternative air breathing engines ...

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 launch. However, the compression of air ...

Another "exotic design" reported by The Register is the SABRE (Synergetic Air Breathing Rocket Engine) which combines the fuel efficiency of a jet engine with the power of a rocket. Using ...

The Sabre air-breathing rocket engine is designed to drive space planes to orbit and take airliners around the world in just a few hours. To work, it needs to manage very high temperature airflows ...

A video and pictures have emerged showing testing of Chinese high-flying and high-speed uncrewed air vehicles, including ...
