Scientists used optical diagnostic techniques to 'see inside' solid-fuel ramjets, one of the most extreme engines in the world.

GE Aerospace and NASA successfully tested a hybrid electric turbofan engine, marking a major step toward fuel-saving single-aisle aircraft.

Researchers have developed an engine that generates power from the night sky by exploiting the temperature difference between the cold air and warm ground. Unlike conventional Stirling engines, which ...

This week, researchers from the University of California published a new study detailing an innovative approach to passive cooling. It can convert the Earth's passive heat into a small but steady ...

His Stirling engine was much safer because it worked on a different principle than steam. Instead of relying on the expansion of high-pressure steam, the Stirling engine is a closed system with a ...

Proven engine family has provided reliable power for agricultural aviation and firefighting missions for nearly 50 years "Pratt & Whitney Canada has long supported the aerial application industry and ...

This engine won't be fueling interstellar missions, but still finds an unexpected way to use deep space energy to generate power. Reading time 3 minutes Deep space may provide hidden sources of energy ...

UC Davis engineering professor Jeremy Munday has developed an experimental engine that can generate mechanical power from the temperature difference between the Earth and deep space when placed ...

Even BMW and Porsche aren’t making as much power from their comparable engines. Like the larger six-cylinder unit, this model punches above its weight, with six-cylinder levels of power and torque but ...
