Astro V Dynafan


This VTOL made by the Astro Kinetics Corporation, is using the "Coanda effect" for vertical thrust, and could be build at much larger scale. The 3 text images explain a lot.

An interesting quote from the text: ".. when we consider that the United States Air Force has spent seven and one-half million dollars on a circular lifting device of different concept and abandoned the project because of inability to perfect the device."

Is he talking about the AVRO projects here? What became of this company and craft? Mysterious!
