New invention of an electric system for vertical takeoff and landing!

[Iraninventions]

Watch this amazing idea and invention of an Iranian genius to develop electric technology in the Airbus A390 that can take off or land vertically using the electric rotating system of its engines. Long runways for aircraft are one of the challenges of European cities that are surrounded by mountains or rivers and lakes. Not needing a runway is a great solution for certain places!

So it's like a helicopter, but way more expensive?

No, Iit is just a fake and totally impractical !
The author obviously has no understanding of engine capabilities, let alone airframe design or strength.
a 380/390 has a take off weight close to 600 tons, and as such would require engine thrust orders of magnitude greater an anything commercially available, …..short of a SpaceX Raptor, with all the , fuel. Emmisions, and operational costs that would imply.

There are real versions starting service in cities around the world.
Appropriately smaller as a way to gain an understanding in how to make them work.

They've been around in the US military for something like twenty years, as in the the V-22 Osprey.
Outside of being a tilt rotor it's best known for crashing to the ground.

Yep. And V-22's can land safely after losing an engine. (In theory at least.) If that thing loses an engine on takeoff or landing, everyone dies.

Hmm, the V22 has a max take off weight of about 24 tons, and uses 15,000 kW of engine power to lift.
…how would that scale up to the 600 ton mass passenger Airbus model ?
The Joby Airtaxi, …well that is electric and we know how diffficult it is to develop a full size conventional electic airliner, let alone a VTOL equivalent .
Soi maintain that a VTOL Airbus is totally unrealistic with any known current technology.

to clarify this for non-aviation-types, this is because the v22 has shafts between boht engines and both rotors so either engine can drive both rotors....but the airbus has completely independent engines, so if one fails there's nothing holding up that "corner".

The Airbus is but an animation.

Yep.

Interesting side note - the cross shaft in the V-22 has an operating life measured in minutes, which has got to be a record in aviation. It's intended only to get the aircraft to the ground safely. In normal operation it spins with both engines, but doesn't transmit any torque.
