- Find out what transition means and the progress we are making towards full flow attachment with Matthias Meiner, Phoenix Chief Engineer & Co-Founder and Hunter Bloch, Flight Test Engineer. #Lilium #eVTOL #TestFlightTuesday
Been following Lilium since the beginning, man it’s great to see their progress and man they’ve grown as a team.
Invest in lilium stock's
@@lillyblack3322 smart thinking
Brilliant design. Would love to see a video discussing the increased induced lift from the accelerated airflow over the top of the wing from the fan placements.
minuscule compared to the angle of attack of the wing.
Congratulations to all the team at Lilium have a safe and Happy Festive Season and all the best for 2023 - Melbourne Australia
So after tinkering around for ten years, they finally started to tackle the crucial issue.
Interesting.
just subbed. Looking forward to your progress
looks like they have only started. What if there is really significant wind, what if there is a power outage during startup with no lift at all ? No surprise, that the share price is dropping so massively. But the team is well financed for a some period. Perfect Frank Thelesen investment.
Great work.
How would the aircraft handle a complete loss of engine power?
Is there something in the way of transitioning to full flow attached forward flight? A stability problem? Low thrust budget?
I really hope that this company succeeds, but I’ve heard that they have only had 3 minutes of sustained flight before draining their batteries
But
Looks cool, but only “a few seconds” of flow attachment achieved so far ? 😬
Electric toys are fun!
Cool
Make the strings go in straight lines. Looks tricky!
you have 4 sets of nearly independent fan structures moving with different controls , make them into 16 structure for redundance and you will lower the risk of computer operated rotational failure clearly your biggest fear flipping during converting from upwards motion to forward motion. Have 16 independent section to reduce failure of one so flights can continue please continue to build these for real world. Great work though guys but still please prove the concept wont fail because your first human casualty will be your greatest stain on reputation

So buy more!
I am starting to lousing my confidens in this project
The slowdown for all of these eVTOL projects will be the certification process. Even now, the requirements for certification are changing, but you can be certain that the end requirement will entail a LOT of data from test flights. If these eVTOLs were being certified as helicopters or as regular airplanes, no one would be worried about or gathering data about "transition". Whatever the FAA and the EASA decide are the final criteria, transition will be a critical area that must be shown to be effective and safe EVERY time. The EASA requirements appear to be much more developed than that of the FAA, so Lilium is working on type certification concurrently with both agencies. But by working on EASA's more specific certification requirements, they will have (almost) all of the flight data they need for FAA certification. It is a slow, bureaucratic process and Lilium is gathering valuable data while the whole process grinds forward.
Just starting?
Can i join your team mates
hmm, once it can rise in the air it should easily be able to tilt forward. This seems like artificial drama. Speaking of which, is the craft unladen? I assume it's unmanned but does it carry payload or is it empty. Are the windows tinted to hide that you are flying empty? if you need to deceive, how can you hope to succeed.
@ Dan Fredeeiksen:
Just go build your own VTOL that will do what you think it should do.
It will be time well spent than criticizing a good effort by people that are actually doing something.
Ijs!
@@kfk256 the premise of your comment is that no one can hear constructive criticism that could help them a lot. And while that is dreadfully true, I don't subscribe to obtuseness and pride being the law.
It's unmanned as stated publicly on several occasions, no claims otherwise... This is not the final version and testing is still on the basic flight physics of the concept again with no claims otherwise...
@@faluffel it could still be laden with full payload. if completely empty the tests are nearly worthless. and how many years have they been at this stage...
@@DanFrederiksen Accusing them of deception without evidence is hardly constructive criticism.
Engineers don't need tough love (especially the slanderous type), they need *positive reinforcement* , sir.
Just fly the plane! Wreck it... wreck several... figure out why it wrecked and you will learn a lot more, faster. Build 1/4 scale models and wreck those, maybe. You people are too slow with all your suits and meetings... You are burning up millions of dollars and have too many expensive people on payroll. AWSOME DESIGN. STUNNINGLY BEAUTIFUL VEHICLE. BUT YOU ARE GOING TO RUN OUT OF MONEY BEFORE YOU CAN PRODUCE PLANES FOR PROFIT. YOU HAVE TO PRODUCE PLANES THAT PEOPLE BUY OR YOU HAVE NOTHING! HURRY UP
@You Tube more investment is a problem. It delays or reduces profitability; which is the same as viability. They could borrow the company to death
You don't understand how money laundering works?
Vertical lift is stupid and uses an extreme amount of power.
Why turtle development ? Ok ... lab xinize virus , but 1 fly by year ??? 3 years since the first fly ( May 2019 ) !!! At least more 10 years to comercial version ... And there is no interior ...
The system has to operate over densely populated areas so the certification is extremely thorough. Have 2 crashes and the company goes bust. The transition phase is the most critical as level flight is super easy. So unless you can master transition, there's no point in going level. You're just bs'ing yourself and the general public.
It's like pushing a baby that can't walk on a bike down the hill. The speed will keep the baby on the bicycle upright but what happens once the bicycle slows down.
That's why we humans first learn to walk, then learn to ride a bicycle with assistance wheels and some of us end up jumping crazy jumps on dirt bikes.
Same with serious aircraft development.

@@easyediblelandscaping2620 I would leave engineering to engineers. Although I like teasing landscapers about why everything takes them so long :-) If it was easy, they would long be in operation.
@You Tube Time is against them in this case. They don't need to look for money. It is thrown at them.
