NASA has just released this 360 degree video of the battery powered, 10-propeller GL-10 Greased Lightning in flight. This is the same video that they show on virtual reality headsets at some conferences. It can be viewed in 360 on many devices.
Developed at NASA’s Langley Research Center, Greased Lightning is currently in the design and testing phase. The battery powered drone has a 10-foot wingspan, eight electric motors on the wings, two electric motors on the tail and weighs a maximum of 62 pounds at takeoff.
Greased Lightning has successfully transitioned from hovering like a helicopter to plane-style wing-borne flight during tests.
