NASA’s Greased Lightning GL-10 Electric Airplane Completes Transition Test – Video
NASA Langley is developing a new electric drone Greased Lightning GL-10, which has a 10-foot wingspan, can take off/land like a helicopter and then transform into airplane.
Engineers decided to use 10 electric motors (eight on the wings and two on the tail). GL-10 weights 62 pounds (about 28 kg).
The current prototype is just the beginning as NASA Langley would like to double the size to 20-foot wingspan (6.1 m) and add a diesel/electric generator.
Below you can see video from tests of the prototype at Fort A.P. Hill in Virginia.
“NASA Langley researchers designed and built a battery-powered, 10-engine remotely piloted aircraft. The Greased Lightning GL-10 prototype has a 10-foot wingspan and can take off like a helicopter and fly efficiently like an airplane. In this video, engineers successfully transition the plan from hover to wing-borne flight in tests at Fort A.P. Hill in Virginia.”
