It’s a diesel-electric with squirrel cage motors?
Nope. Uses Jet-fuel, basically kerosene.
Looks pilotless. Notice, no windshield. A good sized, vtol drone, essentially.
Not Diesel-electric, turbo-electric.
In terms of thrust generated, the multiple fans certainly would spread the downward, then backward thrust more evenly over the airframe. But the structural integrity of the rotating wings would have to be beefed up to a superlative degree.
Carbon-fiber, maybe?
So far as reliability is concerned, an electric cable feeding each of the fan motors certainly beats running some kind of mechanical shaft to each fan. The aerodynamic profile of the lifting surfaces, with the box-fans inserted between them, has to be a matter of some fancy configuration.
It does show they are thinking outside the box. Some similar principles could be applied to helicopter design, while retaining the rotary-wing aspect. A helicopter, in and of itself, is a highly complex design, with the shifting change of aspect of each of the rotor blades as rotor turns, and countering the massive torque that tends to twist the fuselage of the helicopter in the opposite direction of the rotor rotation.
