Lilium is being investigated by at least five law firms following claims it and “certain employees” engaged in “securities fraud or other unlawful business practices”.
Really? It wouldn't surprise me. Can you point me to the information?
They need to start flying with weighted dummy passengers to show that the plane can actually can do distance fly in operational condition.
That is called ballast. Only Joby evtols fly with humans onboard. This stuff is years behind Joby.
@BlueEyed888 joby has flown with one person and they edit the videos every second. Can it lift a person for a full minute? No
This aeroplane would appear to have a successful future. An air ambulance might be just one of many practical applications, as it's more flexible in operation and cheaper than a helicopter to buy and operate. It's a splendid machine in concept and design.
This speech is disqualifying him in so many ways that I am surprised the video is still online.
I love the concept of using the EDF's to pull air over the wing!
Ich bin Biobauer auf der Insel Awaji in Japan. Ich würde Lillium gerne als Transportmittel nutzen, um meine Ernte morgens in Kyoto, Osaka und Kobe abzuholen und auszuliefern. Wir wollen einen Lillium-Port auf dem Dach eines Gebäudes bauen und die morgendliche Ernte direkt an den Verbraucher liefern.
実現すると良いですね
淡路島ってどんな暮らしですか？
... well done - I wish there would be even much more details presented
MP Materials needs to get Phase III and start producing magnets for eVTOL production. Help with supply chain issues.
Of all the evtol startups the lilium jet is clearly an evolution ahead. No dangerous external rotors, 2 means of lift, both direct via engines and via air over wing, which means less power consumption, Safety and redundancy far beyond the competition. ANd for all its benefits that sets it ahead and apart from the rest, its engineering is less complicated. as he mentions its scalable in passangers without drastically compromising the overall scale of the aircraft. its simply a brilliant design.
The efficiency of the design is what gets me. Why haven't we figured this out before? Traditionally we haved used a propulsion device (prop/turbine) to pull the aircraft forward to force air over the wings. The air speed within the vicinity of the propulsion device is greater than the air speed at the wings. In this design they seem to have incorporated that added air speed into the lift equation. Thus creating a more efficient design.
Now this is all really in theory.......? in real world applications, who knows, maybe all the added structure around the EDF'S create some sort of negative effect on the airfoil and create the wrong type of vacuum which creates negative lift?
That's what's exciting about everything that goes into making projects like this. 👍
@@Zachary77 they did, key word being "they" Darpa. and their Aurora Lightning strike XV-24 VTOL, which was something plugged around in the 90's but never seeing fruition outside the digital drafts. Though the XV-24 was a drone never intended for passenger or piloted flight. and it was big. and considerably different mechanically. using one engine to drive all its fans. but the general layout is similar to the lilium Jet. And your correct, the lilium layout with its stream of engine of the trailing edge of the wing does generate aeronautic lift, liftt by way of direct fan thrust as well as reduced air pressure over wing, greatly contributing to overall lift stability control and efficiency. when you watch the lilium jet fly about, that's the one thing you notice, its in flight characteristics, its stability. not only benefiting from the gyroscopic effect of multiple engines on all corners but also that conventional flight control added in. it flies like its on rails. seemingly not suffering much from air turbulence. and it shouldn't because its not fully relied upon wind of wing lift. its a brilliant design to say the least. When i first saw it, it took some time for me to appreciate what i was seeing, as it seemed like a gimmick at first, then viewing with more professional eyes, it hit me like a brick what it all really ment. The removal of the large rotors, being the first to standout to me. And from that alone the increase in safety and operations over its competitors of whom in many ways made an even less aerodynamically efficient design layout than a standard helicopter.
Lilium Jet is the best eVTOL design out there, considering redundancy and simplicity. It is elegant and beautiful to the eye. As better commercial solid state batteries can be integrated its performance will improve along with safety. I wish Lilium Jet nothing but success and profitability, and I hope one day to fly on one!
Vieleicht im Zukunft kann ich auch mit Lilium Jet fliegen! LuftLilium! München, denn neuen Friedrichshafen! Der Adler fliegt!
You think that is simple. :D OK sir.
So they're ducted fan engines, I understand that calling them jet engines might make it easier for people who are not into aviation and engine design to understand that they're more powerful in specific ways than normal prop engines but it's still kinda missleading as there are people working on plasma electric jet engines that work like actual jet engines do.
Yeah, I was frustrated by this. It’s not a jet engine by definition (right?), there is no air compression to improve combustion etc, so why call it that?
Maybe it’s a language thing, those are definitely ducted fans not jets
Maybe this way?: the jet is the aircraft and the engines can then be called the aircraft engines or the jet engines
This is one of the core technology in this aircraft!!! THIS IS A HAIR DRYER!!! What a masterpiece...
3-4 years for a connector regulatory approval ?! crazy? Thats death for innovation.
They could fly it under experimental aircraft certification rules...
If they could fly it they would and have more money from investors to get through certification. The problem is they are bs.
not a jet.
The BIG QUESTION. .Does it have enough energy to be able to be useful?
Battery + ElectricMotor is not more environmentally friendly when you think in terms of *ALL THINGS CONSIDERED.* At least at the current time.
I agree, i don't get this obsession with batteries.
Biggest problem will be the return on investment. Who will want something that has a greater than 20-year payback period?
if you only vary the trust nozzles you would avoid gyro problems with the motors (and get lighter cabling)
Quite interesting and insightfull. Make video about connectors and cables and show differencies, so people can compare it.
👏👍
Daniel's comment stands as a metaphor for life itself. If we knew in advance everything we would have to go through in life, perhaps we'd have some trepidation about getting involved in the first place. Ignorance truly is bliss.
Also: Commercial aircraft certification is a total nightmare even if you aren't introducing a radical new design. Many companies have gone broke in the process. (SyberJet, I'm thinking of you.) Lilium seems to be going about the process about as well as any company could. One wonders if the certification process isn't too strict. But every time you board a flight to Hawaii or land on the helipad of a New York skyscraper, you're glad it is.
An electric ducted fan is not a jet. Who are they trying to fool. Incredibly complex propulsion system! No wonder they are worried about the weight cables and connectors...
Do by plane but offset the twin canard and twin wing can placed double fans
Electric ducted fans not jets, i hope they are fitting a safety parachute
Yes they had a parachute a couple of years ago. There is no way that thing can glide.
They are motors not engines ! Motors convert energy -usually electric or pneumatic to mechanical work - engines convert a fuel to work . This whole misguided project is a scam which is becoming apparent. They are slick and the cute German accent helps give some exotic effect - the 'designer stubble' look is reminiscent of the cast of Das Boot where it was difficult to shave on a submarine --they look a bit like derelicts as it is but that seems to be the Gen X "look" . It is all about looking like something it is not and neither are they.
Who hurt you
@@Leon_der_Luftige Why do you ask ?
@@rossnolan7283 Because you hate on their upcoming product for no reason. Bugger off
He's not so slick when you start asking questions. I think it's a scam, as well.
It was great to hear his thinking on the hydrogen bit but I don't get that argument at all and it can't be right but im guessing hes thinking on the carbon footprint. Still though not a very good argument snd certainly a point that could eadily be adressed if one wished.
Hey there 👋 is me, the icon remember this is the year that I will start flying my 2 sitter special technology aircraft, no blades and is an evtol how about that. The noise of the fridge could be a fare comparison when you are sitting inside. Weight only 340 lbs so it will fly very fast. Thanks God.
Anything more on your design?
sin(engine thrust angle) = thrust/weight
There is another name of an electric jet. It is called a prop.
🙂
How much power consumption per KM ... is the key question. Never answered ? Or did I miss something ?
The hype will die if they answer
..in addition I would like to know, if that plan can "glide" down if the power is off/emergency mode. Or would it drop immediately. I would expect, it drops immediately... Not good, or a significant security issue.
@@markusdicks648 I can't imagine it gliding down considering the weight of the batteries necessary for mid-range travel. However, the power supply can be split into several sources managed independently. This coupled with the redundancy of the propellers makes it safe enough I'd say since chances of most of them breaking down at once is low.
However, the energy density for batteries is still too low right now to support such inefficiently designed propellers. They're aesthetically but the smaller the radius the higher the wastage and no battery technology exists right now to compensate, not if they're aiming at mid-range travel. So I'm in doubt and the fact that they have provided no information on energy requirements so far makes it seem like they want us to believe in their capacity to do magic.
@Will Swift Liliium is by far the most expensive model being worked on and I don't think it would find buyers at such limited range because of that. New batteries are coming but the progress is slow and there is no guarantee that it can even cover 100Km since they have not built anything decent yet despite them having been around since 2016. I really think they're just trying to cash in on us at this point with those videos only providing incomplete information.
00:02 LOL. The blade diameter is barely the length of his hand. This can never carry a load of passengers. It's largely hot air.
Much too loud for urban use. Not a jet other than the noise it makes.
Harika bir helikopter uçak.
Abi saçmalama insan ayıklıyorlar. Arkasındaki uçak maket 1/10 boyutunda bir maketi anca uçurabiliyorlar. Bu uçağın teknik olarak günümüz batarya teknolojisiyle uçabilmesi imkansız. :D
Sorry, but these are NOT JET ENGINES! Ducted fan engines. No combustion of fuel takes place. This is pure marketing hype and spin by Lilium
Every Lilium says is hype and spin. The German Theranos.
So glad I chose to invest after studying their approach to safety, pax count and efficiency of flight. I have every faith that I am part of a succesful technology taking a step into the future.
Close to bankruptcy, stock plummeting.
Not a jet engine.
This guy has been fired by the company board of directors. Lots of promises but nothing to show for it.
Is that really a jet engine or just an electric fan? A jet engine is actually by definition a gas turbine...
In my opinion, what he's saying is technically speaking, well, dubious to say the least...
One of the major problems I see (actually hear) with Lilium's aircraft is the very loud noise level and high pitch of that noise level based on their own videos I've seen (and heard). It's an electric jet engine and it sounds like a fossel fuel jet engine. Lilium really needs to concentrate on drasticlly reducing that noise level and the pitch of that noise level if it wants to operate near residential areas. I definitely would not want that flying over my house nearby.
I've also read that there are other problamatic issues with energy consumption probably from running so many electric motors perhaps.
And finally, I read that the cost of the 4/6 passanger version is more than twice that of Joby or Archer's 4 passanger eVTOLs, that would be another major problem.
Your tech is beautiful but your ducted fans /multibladed props are NOT ' jets'
These are ducted fans, not jet engines!!
That’s how you can spot a scam !!!!
jet noun:
_ A rapid stream of liquid or gas forced out of a small opening.
So, a High Bypass "Jet Engine" is not a "Jet Engine" because it's not a "1950's Turbojet Engine?"
Notice that very few Commercial Aircraft today, do not use "Ducted Fans" for "Propulsion Efficiency!"
Modern passenger airplanes don't use jet engines either. They use high bypass turbofans. It's more like a gas turbine driving a ducted fan. The jet of hot gas contribution to propulsion is negligible.
So you have to separate what most people think jets are, vs the technically correct definition anyway. And obviously a marketing video will always use the colloquial meaning.
This is genius.
The Lilium is far and away the most thought-out eVTOL so far.
It's the same as the rest. All promise and no proof.
Hilarious, if someone talk about naivety while being naive and showing that even after 7 years he still doesn't have an aircraft flying with a pilot on board and no horizontal mode flight even without a pilot on board ... I hope Lilium will at least make some money creating the infrastructure for competitors who have flying vehicles that actually work.
The fact he talks about these high power ventilators to lift 16 people and can do horizontal flight is just most ridiculous thing anyone could say.
Perusing these comments, we see a lot of tech-challenged, obsessive trolls whose only criticism that they can dig up is lexicological in one's interpretation of the word 'jet' without a clue as to the sophistication of the design. Ask the Wright Brothers about these idiot personalities...
It's not a jet engine, it's a ducted fan. You can't even get basic definitions correct
Where did they find these guys, GQ magazine? You know Boeing engineers do not look like these guys 🤣
Yeah, they're Americans so they are overweight and sloppy...
Wrong still. There is an emission, it's called electro magnetic radiation. Travels the speed of light. Spread that across a city, someone's bound to get vertigo.
These are just ducted fans!!! Nothing to do with electric jet!
TGAT’S HIW TOU SPOT A SCAMMER!!
...illiteracy is how you spot an idiot.
@@cptairwolf be careful with saying something like that...... Its similar to calling someone a "stupid ignorant fool". Technically speaking, ignorance is a lack of knowledge. Stupid/fool, have the knowledge but choose not to apply it properly.
I can build you a house, a car or even put together a computer system, but I will admit English is one subject I failed, terribly I might add. Lol!
Having said all that, I do agree with where you were going. 👍
@bobjob3632 can you please explain the non electric part..?
