Divergent thrust with a perimeter air induction (
from what I can tell)...................will it function as claimed?
VENTURI ENGINE*

We came up with a revolutionary Venturi engine and a hybrid aircraft schematic that combines that of a airplane and copter without the transitional regime. These technologies will allow us to see the future today! This unique electric engine is based on the Venturi effect, the meaning of which is the following: the ordinary atmosphere air is injected to the output stream of the engine, creating an additional stream and reducing the noise of the high-speed jet inside the stream. This gives a significant increase in engine efficiency and noise reduction. Our patented engine are 2 times smaller and much safer while having the same thrust as a propeller, this is because all rotating mechanisms are hidden inside the body.

I'm assuming an axial fan driven by an electric motor.
