It like one from Star Wars, except slower (for now!!) - Tandem-Duct Aerial Demonstrator (no audio). YouTube
In January 2012, Aerofex presented its recent work at the American Helicopter Society Future Vertical Lift Conference in San Francisco. The technology discussed utilizes ejector dynamics to augment the thrust and control of ducted-fan aircraft. The goal of the effort is to simplify vertical flight, in this case by eliminating the complexity of cyclically-variable rotors.
The technical paper is published and distributed through the AHS. The presentation video, shown here without the benefit of narration, documents the technology's effectiveness through a sequence of flight maneuvers demonstrated on a manned aerial-vehicle.
