A turbofan engine is an engineering feat. Here's what to know about how a jet engine works, from the fan in the front to the hot inner core.

The modern fighter jet is defined by its engine, which accelerates a tremendous volume of air rearward that it can propel an aircraft weighing as much as 70,000 pounds at supersonic speeds. While ...

Jet engine output is measured in thrust, not horsepower. Thrust reflects the force moving an aircraft forward, making it the standard metric for jet power.

Jet engines that you find (most commonly) or airplanes have a particular kind of fan that helps make the whole thing work. Here's what it does.

The waterborne jet works on much the same principle as the airborne ramjet. It consists of a roughly cylindrical chamber with openings at both ends. As the engine moves forward, water comes in the ...
