The unprecedented development of the space industry means not only that more and more aerospace companies are trying to make satellite launches affordable and effective but also that new launch ...

While they're not quite ready for production, the printed parts were lighter, ran cooler and unlocked more power than the standard forged pistons. Antuan started out in the automotive industry the old ...

With an avalanche of private space companies upon us, the number of engines meant to carry rockets and their cargo into space has grown rapidly over the past few years. This world is now dominated by ...

3D printing is a powerful tool for creating all kinds of stuff, but it has its limits. Hobbyist-focused machines that dispense melted plastic through a nozzle can only make parts that are so strong.

Although today’s rocket engines are advanced and powerful, they tend to rely on traditional — and naturally volatile — fuels. Firehawk Aerospace has a safer and more stable new solid fuel, new engines ...

UK-based space startup Orbex has unveiled the world's largest 3D-printed rocket engine. The single-piece, cryogenic liquid-fueled engine is installed in the second stage of an engineering prototype of ...

A normal Wankel has a triangle rotor spinning in a peanut-shaped housing. Liquid Piston flips that; now the peanut rotor spins inside a triangle housing. That small change makes a big difference. The ...
