Stealth Drone

About 15 years ago I contacted an engineer at NASA Lewis Research center about unducted fans, or propfans. He sent me all of the engineering data NASA had (it's public), and I always wanted to design one. The technology held much promise, but were too loud for airliners and maned aircraft. So for fun, why not put one on a drone? I may actually work some more on this, creating a real aerodynamically sound fan and high altitude wing. But for now it's just another project in my rapidly expanding project file.
