Not this one out of Seattle, though. Jetoptera's J-2000 concept is a remarkably different take on the VTOL inter-city aircraft, designed to make use of the company's own unique propulsion system. Much like the bladeless fans popularized by Dyson, there are no spinning blades to be seen on Jetoptera's "fluidic propulsion systems (FPS)."
Mind you, as with the Dyson, there are most certainly spinning blades elsewhere in the system. Both devices rely on fluid dynamics to take a relatively small flow of compressed air, and use it to suck a much greater volume of ambient air through at speed. Sir James Dyson does a pretty good job of explaining it here in the context of his fan, which uses a small, quiet impeller to generate pressure around an aerodynamically shaped loop until it exits at high speed through a slit running around the ring.
