Turbojet engines are an incredible piece of 20th century engineering that except for some edge cases, have mostly been replaced by Turbofans. Still, even the most basic early designs were ...

Designing a combustion engine can take a lot of time, like three to five years. What if you could cut that time in half? For Lumenium LLC, a Virginia-based startup developing an innovative family of ...

Agnikul Cosmos has fired its Agnite semi-cryogenic engine with thrust sweeps and a long-duration run. The test adds ...

The promise of 3D printing in automotive applications is clear for all to see, but it still takes clever engineering to get the most out of the futuristic process. It likely won’t come as a surprise ...

For a long time, the world of 3D engines — especially for game developers — was all about Unity and Epic’s Unreal Engine. Then, when Amazon started its ill-fated attempt to get into gaming, it ...

In this video, we explore the significance of NASA's new 3D printed rocket engine, which is 20-30% more efficient than ...

Some folks just can’t leave well enough alone, and that often ends up being a good thing. Such is the case with this 3D-printed compressed air engine, which just keeps getting better. The design has ...

The volatile nature of space rocket engines means that many early prototypes end up embedded in dirt banks or decorating the tops of any trees that are unfortunate enough to neighbor testing sites.
