NASA's Greased Lightning Tests Vertical Takeoff

• http://www.popsci.com, By Kelsey D. Atherton
The space missions get all the credit, but the Aeronautics branch of NASA does really cool stuff. Today is National Aviation Day, and to celebrate, NASA shared a picture of their GL-10 Greased Lightning drone. Consider it the little sister to the military's V-22 Osprey. It has a ten-foot wingspan and boasts ten electric engines all on tiltwings. Seen here, the wings are pointed up, letting the drone take off and land like a helicopter. Once airborne, they'll tilt forward, making the plane much faster. It's a best-of-both-worlds configuration, and NASA wants to make it better.

Greased Lightning is part of a NASA program to make efficient hybrid-electric Vertical Takeoff and Landing aircraft. It's one of four concepts, and is the most conventional of the bunch.
