John Bucknell presented his updated Turbo Rocket plans at Space Access 2019. John has previously worked on the SpaceX Raptor engine and has presented a nuclear air-breathing rocket design. The new ...

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.

In other words, this approach hampers mission performance, mission payload and mission time. SABRE, on the other hand, is a hybrid air-breathing rocket engine. During the atmospheric segment of its ...

NASA bets on air-breathing rockets--but what are they? NASA hopes to revive a stalled technology, bringing the cost of space travel dramatically lower.

The core engine then takes air from the precooler, and forces it back out through relatively conventional rocket nozzles.

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’ ...

A new type of engine combines the speed of rockets with the gas mileage of jets in a single package. Led by aerospace and mechanical engineer John Bossard at BSRD LLC, the team has built and tested a ...

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 ...
