Any relation between that Lilium Jet and Aurora's DARPA effort?  Are they close enough in design to cause a ruckus re. patent infringement?   ???
"DARPA Hard"  It ain't what it use to be.

The concepts are pretty close, but Lilium carries the fans on the flaps to point them down, Aurora's tilts the entire wing.
One thing that the lilium video on their website does not show is full wingborne transition, which is tricky. I'm also kind of annoyed they call their ducted fans "Jets".

Yeah, that was the first thing I noticed as well. It sure doesn't look like the Brayton Cycle to me. ;)

They've also gone through several iterations. They've given up on that retractable canard which characterized the early concepts. I guess they realized that with the cg in the middle, and the wing in the back, they still need lift in the nose to make things work. Their latest iteration looks somewhat closer to the XV-24A.

It seems to me that uncowled props/rotors in those positions would be a potential hazard, in ground handling terms.

From the video it seems as if the entrance and exit is only planned from the front, requiring some kind of gangway.

Cartercopter teamed up with Mooney for their electric "UBER ELEVATE AIR TAXI CONCEPT" VTOL

Press Release:

indeed, the first iteration of Uber vehicles will operate from 'vertiports', which allows you to take advantage of some ground support equipment. Obviously any door-to-door service, which could theoretically land on unprepared surfaces like someone's backyard, would require a different layout. You'd probably want to put the rotors above reach of passengers.

@mboeller: thanks for posting the presentation!

They really went out of their way to conceal any hint of the dynamic systems used in this concept.

Video about this



Bells Homepage about "Air Taxi"
http://bellhelicopter.com/company/innovation/ces-2018

This let to wild Internet speculation  about Air Taxi drive system
going over "Blade Runner" and anti-grav units to oversized quadcopter
some sources like the Video above tell that Air Taxi is electrical power Helicopter
and Video on Bell homepage suggest it also automotive,
There is no pilot in that video and passengers not using the controls.

There's really only one logical system to consider:

And so the endless circle of life comes to an end, meaningless and grim. Why did they live, and why did they die? No reason. Two hundred million years of evolution snuffed out, for in the end Nature is horrific and teaches us nothing

I can think of more than a few people who many would pay to see moved by this transport system.

I would think an electric helicopter would be more efficient than a giant electric quad/multi-copter.  A distributed lift electric hybrid that transitions to wing borne flight would beat that but for short hops across a city an electric helicopter might be adequate.
