Unrealized Dream of Supersonic Trains

What if trains could travel at jet speeds without leaving the tracks? In the mid-20th century, engineers experimented with equipping locomotives with jet engines, promising airline speeds on the rails ...
RDE is a propulsion system that promises higher power, greater fuel efficiency, and lower emissions than conventional rocket or jet engines. The RDE generates thrust by sustaining a circulating ...
Throughout its brief but interesting life, the Progvev-T encountered numerous problems that ultimately doomed this gonzo idea to obscurity. The Cold War was a time of extreme experiments when it came ...
We've all thought about what would happen when you pour jet fuel into a diesel engine. Will it work or lead to immediate catastrophic failure, perhaps even an explosion? Planes are among the most ...
The combination of advances in engine management technology, in the design of heat exchange technology and the chemistry of ...
In more ways than one, being a fighter jet pilot for the U.S. Navy is a lot more demanding than being one for the U.S. Air Force. After all, while taking a plane to the sky and landing it is something ...
