Worth posting this quote
"The widely proclaimed transition in early June was a
main wing transition, not a transition for the vehicle (canard + main wing). Such a transition is yet to be made."

Some impressive fundraising happening at Lilium and plans to build 25 units next year, followed by 250 the following year.

If your a follower of Lilium with a couple of hours to spare then you might find this analysis interesting, personally I would be delighted to be posting a link to a manned flight but that still seems to be just a dream.

Though we're not sure what you were trying to imply, you are certainly welcome to post your comment. On topic, watched the video and it'll never fly; it's unbelievable people invested in its company.

Why do you say it will never fly??
I believe it will reach commercial flying status. It has so much going for it due to not having rotating dynamic components anywhere.

I'm open to their general concept, distributed fans are not a bad option, however, they have to achieve a high efficiency, and while it is likely that a Coanda effect will occur that can be subject to variables. There is likely some redundancy with the rear wing, the front wing looks to be lean on redundancy. Perimeter driven electric motors, would have a low mass and high torque, remaining with standard designs or even Tesla type motors would not be my choice. scaling them down to run the fans would be needed, they were used to replace a B206BIII TR/TRGB/TR drive and TR control system and needed ballast to be added...

Battery mass is going to suck. and you get to carry the flats along for the ride.

Another $190m to grease the wheels toward reaching the regulatory finish line. https://lilium.com/newsroom-detail/lilium-releases-q2-2023-shareholder-letter

I'm surprised that after the time and $$ they are apparently still developing a power unit.

*Very* informative webinar on the subject of batteries. Includes performance, manufacturing and regulatory aspects.
It is a pretty good 101....
They compare efficiency of lift fan with tilt rotor, (think of Wisk Aero as their competition)
​​​​
Charging will be CCS standard.
1st fleet will have a 175km range with a reserve. 6 full size prototypes begin production Dec 2023, manned flight test 2024.
They assess an industry growth rate of 4% per annum in battery power density.
They make predictions of an increase in range to allow flights from Munich to London
The battery in launch models will have 800 charge cycles (100-0%) which equates to 1200 flight cycles, with cycle degradation resulting in 88% battery capacity.
Battery cells can be replaced.
New battery cells will require stc.
Key battery developments are use of silicon anodes with the tech being commercialized in 2024 and 2026.

Production goal of assembling an airframe in two days
 
The head of industrial Julie Spanswick puts her neck on the line, stating that their production goal is rolling out an airframe every two days. Julie was the former manager of airframes at Airbus.

At least they are showing seat belts in the renderings now...

There will be a lecture about it at RAeS HQ next month: https://www.aerosociety.com/events-c...he-lilium-jet/

Seems like an in-person event only?

I suspect it will be available to watch online later. Here is last year’s
