ROTOR

Ever thought about how we can make sure power grids work smoothly? Scientists are finding new ways to do that using smart tech. One problem is that the rotor angle—which shows how power generators work together—can go haywire. Traditional methods don't always catch this in time. That's where a cool

Airbus CEO Guillaume Faury is cautiously optimistic about CFM's open-rotor engine technology, but is it enough to convince the industry? The innovative design features a massive 14-foot diameter fan, non-rotating variable-pitch stators, and the promise of improved fuel efficiency. But can it deli
