Thank you for sharing that. Not only is it an interesting aircraft, but the page answered my main question about this type of control system design, which was "is it using the Coandă effect?" Years ago, when I read about the original grandiose plans for the Air Force's Y-2, one of the aspects I thought was very interesting was the ability to create a "virtual airfoil"[1] via the Coandă effect. It seemed like one of those designs that was impractical with a human 100% in control, but that might come around again with computer assistance or a fully computer-piloted aircraft. Pretty neat that someone already made it happen. [1] https://en.wikipedia.org/wiki/Avro_Canada_VZ-9_Avrocar https://en.wikipedia.org/wiki/Avro_Canada_VZ-9_Avrocar has a brief discussion of this.
