One factor practically all air taxi ideas share in frequent is fast-spinning propellers or ducted followers someplace outdoors the plane’s fuselage, pushing air to develop thrust whichever manner they’re pointed.
Not this one out of Seattle, although. Jetoptera’s J-2000 idea is a remarkably totally different tackle the VTOL inter-city plane, designed to utilize the corporate’s personal distinctive propulsion system. Much just like the bladeless followers popularized by Dyson, there are not any spinning blades to be seen on Jetoptera’s “fluidic propulsion programs (FPS).”

Mind you, as with the Dyson, there are most actually spinning blades elsewhere within the system. Both units depend on fluid dynamics to take a comparatively small move of compressed air, and use it to suck a a lot better quantity of ambient air by at pace. Sir James Dyson does a reasonably good job of explaining it right here within the context of his fan, which makes use of a small, quiet impeller to generate strain round an aerodynamically formed loop till it exits at excessive pace by a slit operating across the ring.
The air is pressured again over a wing-shaped floor throughout the ring, the place it develops the identical sort of adverse strain that provides plane their elevate. In this case, although, any elevate is canceled out by equal adverse strain zones throughout the ring, and the online impact is a low-pressure vortex within the middle of the ring that pulls ambient air by at an ideal price.
