- Why is the Lilium Jet a jet - in fact, the world’s first eVTOL jet? Julien Rasse, a Senior Test Engineer explains. He compares the streamlined architecture and ducted electric engines to classic aircraft and open-rotor eVTOLs. Julien also takes us into Europe’s biggest wind tunnel facility where the team is testing the aerodynamic interactions of the Lilium Jet.
The data gathered in these meticulous tests has helped refine the performance and efficiency of our design, maximizing safety and functionality.
#Lilium #eVTOL $LILM
This is the most beautiful aircraft I have ever seen. Bravo, Lilium!
Unfortunately it hasn’t flown yet.
That's amazing!! I've been invested in this company for a year or more, and I can't wait to see people flying them!!!
Will never happen. Bad investment.
As the wise man said, we'll see 😂
I haven't wanted something this badly since 2013. I want this very much!
i have the whole blueprint, if you got the money, we can make one.
please keep pushing! really loving see more & more of this unique VTOL
Fantastic!!...always a pleasure to get a view on your progress...by far the best eVTOL.
Great to see further progress on what is my favourite concept in the e-VTOL world. Kudos to the Team.
Beware though...it's been pure marketing thus far
Love this! Cannot wait to see it fly and be put in service!
More marketing terms to abuse the word JET. Might as well call it a rocket or levitation or a spacecraft. Tell Julien to hit his engineering books and look up the term JET because this is not. It's a ducted electric fan, not a jet engine nor a jet. Although I think marketing is the one who is abusing this term to lie to the public.
It's a turbo prop rocket jet.
was going to say - like the abused ‘turbo’
A jet is a forced stream of fluid. Cuttlefish utilize jet propulsion. Hope this helps.
@kingsleyzissou5881 the fluid being released is the jet not the squid. A jet in regards to aircraft classification has a different definition.
When 30 leaf-blowers are connected, they become a jet...I guess
i love creativity in aviation, good job! keep up the good work!
Why do I get the feeling they spend more on marketing than engineering? Their videos seem scammy too.
4 videos in 2 month. wow
It is a scam these aren’t jet engines
Deffo it's all BS. Get a CT Rotax or a shark that sips fuel and can go 1200NM. Everything electric is a con, batteries just do not have the energy density.
Years ago, they produced very few videos, and then they were accused of hiding and not publishing any information. Now they're making more videos, and that's wrong again. You can never please everybody..
Its not right . Thay make Marketing only since one or two years but thay work since 11 years on this company and on this idea. That show clearly its completely different... thay made a lot more engineering than marketing .

"The world's first vertical takeoff and landing jet,"
Allow me to introduce you to the Harrier jump jet, courtesy of Hawker Siddeley who first produced it in partnership with British Aerospace, Douglas & Boeing / BAE from 1967 to 2003. It is a VTOL and VSTOL strike aircraft currently serving in the United States Marine Corps, Spanish & Italian Navy, though it's been retired from the British Royal Air Force & Royal Navy since March 2011.
I'm aware this may not be an apples-to-apples comparison. The Harrier was fitted with a Rolls Royce Pegasus 6 engine, a turbofan engine with swivelling nozzles, whereas the Lilium has 36 ducted electric vectored thrust (DEVT) fans. But don't claim this is the world's first VTOL jet when you can so easily disprove/pick apart this statement (I'm aware this is most likely just marketing doing marketing).
1:38
"A helicopter or most open-rotor-based cabins are boxy, ours is built for the streamline."
It's safe to say that this is just a marketing term. There are countless examples of aerodynamic rotary aircraft, such as my favourite the Eurocopter AS365 Dauphin used by the British SAS and dozens of other countries' militaries.
1:47
"These jet engines are very similar to a traditional aircraft, just without the combustion. And unlike open rotors, those engines are scalable, safer and less noisy."
I think we've agreed on the fact that these are not jet engines. Just call them what they are, DEV fans or thrusters. The only similarity they share with a turbofan is that they have a rotary component. Much lower RPMs and aerodynamic + mechanical stresses here. No fuel other than electricity is being used. I do agree however that DEV fans are scalable, safer and less noisy because of the far fewer components and previously stated points.
In conclusion, after watching the entire video I have to firmly push back on calling this a jet. I agree with what others have stated here, the term jet is being used as a marketing term and holds no operational value. By this logic, you could call a Douglas DC-6 a 'jet' when it's a piston-powered cargo aircraft (surprisingly some still fly). Of course, the marketing department does have to do the polishing with what they have so that is understandable, but others need to understand that a DEV fan ≠ jet engine or jet aircraft.
That being said, the US NBAA has an interesting article on what defines a jet aircraft (not the jet engine and this article is about a private jet):
- One or more gas-turbine engines
- Capable of flying higher and faster than piston or turboprops, catered to businesspeople
- below airlines (20k-25k ft) or above (>40k ft)
- Varied size & range, average 1k miles

Thanks for reading, fly safe.
it's comments like this that grab my attention, well done research, precisely put forth points, and diplomatically written opinions.
Good job mate, for educating people here more than the video.
its still not the same thing. this is revolutionary
First VTOL transport Jet was the German Dornier Do 31. First flight February 1967, long before the F-35B and 10 months before the Harrier’s maiden flight.
40 years old and already a senior test engineer.
I predict this company will be still syphoning research funds for 5-10 years and will evaporate into the clouds of stockmarket together with the investors money.
It will not last that long.
Is 20 years experience in wind tunnel isn't enough?
@@mariusmartinsen2064 someone with 20 yrs of wind tunnel experience and happens to be an aerospace engineer should know this is garbage. Yet he’s got the audacity to be in front of camera to promote the aircraft and this cringy marketing videos they constantly makes me laugh
Exactly. Nowadays, we are living another form of dark decade that lots of hype and overly confident dodgers.
I've been following this project for a few years now.
Do you guys plan to use remote controlled units to assist emergency responders?
What about units for first responders or extraction of emergency pacients?
Also, what are the harshest conditions in which it can fly?
It‘s designed for premium passenger transport not for air medical services.
As soon as I see cool interior shots, I check out. Humanity is burnt over and over again with cool marketing shots
It doesn't makes any f sense? 🤣
Lilium will be BIG ONE!
Great project, looking forward to seeing more updates. The question is not "Why call it a jet if it takes off vertically?" as there are plently of jets that take off vertically. The question is: Why call it a jet when it doesn't use jet propulsion, and therfore doesn't fit the commonly accepted "jet" definition?
You just answered your question yourself 😂 now go and check what is jet engine..
@@mariusmartinsen2064 "a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion". If I read and understood correctly this doesn't fit that description, as the gas is not heated.
It's a marketing play. A jet has a jet engine. These are not jet engines, they're ducted fans.
That's right. They're just using the JET name to attract amateurs, aren't they?
@aaron8862006 A jet is a rapid stream of gas forced out of a small opening; see Oxford dictionary.
Both a ducted fan and a “combustion jet engine” (as on airliners and fighter aircraft) create a jet, namely a highly accelerated air stream that provides the thrust needed to overcome drag and propel the aircraft forwards.
Hence naming the Lilium “jet” is as correct as a Gulfstream jet. Cheers!
Jet means flow of air for example a jet stream that being said my design is much better than these people.
Show me on the doll where the evtol hurt you 😢
@@wouterplaetinck6887is your rear end a jet?
Bag of ... I was unaware that all the footage shown was of a subscale model (if so ) --there are conspicuously no photos of someone standing next to it now that I think about it , It is certainly meant to convey a full size test aircraft (there are photos from above of a full sized vehicle - I, and I think electric aviation , used the humans to try to work out dimensions . The array of small diameter fans strung out along the wings is reminiscent of the Russian Caspian sea monster 'Ekranoplanes' and is also featured in several tech papers long preceding lilium . the figures given for range and speed were for flight at 10 000 ft which is the legal limit without oxygen and unrealistic for short ranges especially given the cost to climb and airbrake effect on descent .
I'll look into the scale thing, thanks for the info.
They have full scale mockups they sometimes stand next to but not the one they flew. They have some cabins they show that people sit in but they don't have wings. They have never flown a full sized craft capable of lifting a person. They say they will have one this year but I doubt it.
In all these years have you flown with even a single person or person equivalent weight?

@@mariusmartinsen2064 stinking = not buying in to meaningless marketing?
"BagOfHolding" is what we call dumb money in the market
@EarthCreature. in 6 months the year will be over and they will not lift a person longer than 3 minutes. I doubt they will even have a full sized craft that will lift its own batteries for 3 minutes.
Beautiful
I'm really looking forward to the first successful official flight with passengers
when gravitation has vanished
Will you be onboard?
@@avigator he will climb in and they will shake the the hull a bit
@@schaeferfilmthey will show people walking up to it with helmets in hand then edit to it starting to take off empty then a few seconds long edits of it hovering then edit of it starting to land but not all the way then a shot of it on the ground with people cheering.

@@TheBagOfHolding sounds a bit like Apollo 1969
These are incredible aircraft. The move to electric aircraft seems to be in very good hands. Thank you for sharing this and best of luck!
You do know none if this is new and these aren’t jet engines

These serious people are truly making a revolution, but few smart people understand the value of their work. I am an Arab person and I appreciate your effort
But you are not an aerospace engineer, are you?
"Avigator" is far from any sort of engineer so.. 🤣
You missed the test where you do a test flight with someone inside.
They missed the test with a full sized empty craft.
They have actually done a full first flight test
@@Secretlyanothername they never even made a full sized craft. When do you think they did that?

The harrier looking from the distance!
Yeah fr, these dudes havent heard of fighter jets before. Even the famous F-35 came before theirs
@@PilotekzyWTf35 can only land in vtol. But yeah, the Harrier.
@@kael13 F-35 CAN do a vtol takeoff, Theres bunch of videos online
Still operating on this scale... I dont believe this thing will fly in actual size soon, if ever.
imo the problem with the lilium "jet" is that electric ducted fans are very inefficient which increases the power/weight problems with batteries. maybe they can make their EDFs more efficient, but they wont make better batteries themselves i guess. so unless batteries improve, this wont be viable
They been flying a full scale mock up. Where have you been?
@@mikeg3810 source?
ruclips.net/video/sQJkHDwNvkk/видео.htmlsi=Q9XrVxgr7yeBYGcc@@WakkelPudding_
@mikeg3810 they never did.
Perhaps LILIUM is big company some day!!
1:56 arent EDF MORE noisy ?
Just listen to your neighbour with his leaf blower... It has about 2 KW. Here you have about 2000 KW blasting away air at super high speeds
The idea of using actual wings as a mode of forward flight in VTOL versus thrust only will greatly extend the range. I don’t understand the idea of using props alone for flight over both props and wings. With wings a power reduction can be realized as the craft is supported by the actual wings. Good on these guys for doing it the right way first.
Please publish price, cost per flown hour,flight time, range, payload, service ceiling, cruise speed, charge time and whether will be certified for IFR.
You have time to comment, but no time to visit lilium website, read presentations, check videos with CTO, CEO etc? 😂
You spend all these time in wind tunnel but not a second showing the aerodynamic results
Yeah because the aerodynamics sucks, I can see it with my eyes. I dont need special computers
Which company does?
@@PilotekzyWT yooooo😂
@avigator usually companys that show their vehicles In a wind tunnel for marketing have a cool looking smoke trail gliding over it to show how smooth the flow is.
He's apologising for calling it a jet when it's a ducted fan
@SimonRockman A jet is a rapid stream of gas forced out of a small opening; see Oxford dictionary.

And what about the Paris Olympics ?
Will Lilium start there - or not ?
I can remember the big buzz about that Paris Olympics and now no one is talking about that which is more than disappointing.

It was Velocopter other 🇩🇪 company for f sake 😂
@@mariusmartinsen2064Volocopter! 🙄
Great work guys, step by step it all comes together 💪💪💪
Only thing that's coming together is marketing
Could this be referred to as a flap-jet or blown wing design? Placing propulsion on the flaps for VTOL performance seems quite advantageous to me.
this channel should have a minimum of 1M subscribers, man you guys have come a long way.
and still the goals to achieve are far away
@@avigator Sad but true, however good progress produces results and these guys have been producing a lot of it. Lilium and Archer are doing their thing and it is great to see.
A long way in the wrong direction.
Well, you're allowed to have an opinion.
Awesome
So glad these guys are going through all the work of showing how ineffective this design will be with its extremely low efficiency
It is now 2024....nearly 8 Years after their first model flight... Isn't the electric architecture to be simpler...hope their funding has the unlimited money glitch on active
Electric rotor blade system is simple, it was here, tilt mechanics was here.
Lilium went different way. Airplane/Evtol in general isn't a EV, it has slower progress as standards is different especially gov regs, safety etc.
Nobody at lilium want to rush unproven tech, get jet to sky quickly just entertain inpatient investors and if it fall down nobody will want to fly or buy. I like that Lilium takes time to pay attention to detail and work heads down.
@@mariusmartinsen2064 is knowing a bit about aviation, and regulatory approvals eg I'm not confident at all about this project. Just assuming their monthly Capex I just hope for them, their funding is sufficient. Good luck
Masterfully produced video that really shows of the beautifull flowing shapes and how you put real effort into designing the cabin. I espcecially like how you did not address how you plan to produce the roundabout 2000KW+ necessary to lift your vehicle because it is using such a tiny rotor disc area.
First vertical take off and landing jet my arse. Harrier jets (e.g., AV-8B Harrier II, British Aerospace Harrier II) use directed jet thrust for VTOL capabilities. F-35B Lightning II... and your aircraft does not have jet engines anyway.
@michaeljohnson3383 a jet engine is an engine that strongly accelerates air to .. form a jet stream that gives the thrust force to overcome weight and drag. Your examples and the Lilium jet have this in common! Combustion is just one way of creating the jet stream.
@@wouterplaetinck6887it doesn't accelerate the air it compresses it for more oxygen and greater combustion. Lol you must be one of their engineers.
Was Harrier electric? 🤣 Lilium is first evtol.. And whatbis JET definition?
@mariusmartinsen2064 the guy in the video said it was the first vtol not evtol.
@@TheBagOfHoldingwow.. You look like CTO. What is a Jet engine and Turbine engine? Go back to every your comment and apologise for being lazy to research whatvis a jet and how air is used in jet 😂
Genuinely good luck, but I think you should tune down the marketing. Trying to call it a jet when it factually is not is going to upset people much more than whatever perceived benefit you will get out of this. As per usual, honesty is the best policy.
The world's first vertical takeoff and landing jet? Come on guys, you can't just say whatever you want.
lol. These guys have no shame
first electric vertical takeoff jet.. this seems cool, good idea to fill in the gaps that arent there in the world.
Interesting to see who will be the first certified , first to market at scale , and the first to 1000 aircraft - Lillium , Joby or Archer. Any other worthy contenders ?
Have they not heard of the Harrier?
Was Harrier electric? This ia first eVtol
@@mariusmartinsen2064harrier used electric vtol control system, what are you on yapping about
cool!
Will it glide without power? Can it be controlled without power? How long does it take to charge?
No its fly by wire and would likely become unstable without power. No parachute either. Poor souls that get on it.
@@JoeyBlogs007 That's my assumption which is why I'm asking. I want proof that it's not the case. Is their certification for flight an example of the government looking the other way because it's "green". My first inclination is to see this thing as being a cool idea, a cool design, but it's impractical and dangerous.
@@JoeyBlogs007 Dumb af. It will have a parachute if you want one. You're talking about stuff you have no idea about.
@@jimberg98 Lilium is made in Germany, not chinese or american. That alone should be give you a clue. But you can also make researches, go visiting their websites.
@@jonpetter8921 You don't think I looked? They're evasive about these questions because they know the answers aren't good. Are you seriously equating Chinese air safety regulations with American? Being made in Germany? Like VW? Remember how VW programmed their ECU to pass emissions while being tested, but behaved differently while on the actual road?
Seems that it could still land horizontally if it had the wheels for it.
I wonder how few motors are required to be operational to maintain level flight?
I wouldnt be surprised if the answer was 2.
Dornier Do 31 ?
Truly beautiful design, would like to see handicapped friendly ground level entry.
Would rather fly this through a flock of birds than joby or archer! Lol 😮
I suggest that investors go look at the hype surrounding the icon A5 when it was introduced about 15 yrs ago. Same thing: lots of buzz, glitz and glamor. They hardly sold any and are out of business now. IF we continue to make incredible advances in battery tech - not assured - this might work for short flights around cities, but considering its already far more expensive than a helicopter, this doesn’t seem viable.
Add a small gas Turbine tied to an electric generator (APU) and you've got very high efficiency and added safety
I don't know what they're talking about with being the "first VTOL Jet." The f-35 has been around for awhile and it has VTOL capabilities.
First VTOL transport Jet was the German Dornier Do 31. First flight 1967, long before the F-35B.
You fail at context. It's an ELECTRIC JET. You half wit keyboard jockeys are hilariously self owning
What is the sound compared to a helicopter in new york? Less decibels? More?
why dont you mould the wing around the engines? so the intake is the leading edge of the wing? you could mount the engines in the same place but lower and the engines would be in the aileron position and able to move but draw air through the wing making like a biplane effect and giving more lift.
Keep up the good work. Really looking forward to seeing one in person
very exciting. really hope this succeeds. all other eVTOLs are ugly-looking compared to the Lilium.
I'll take an ugly craft if it's safe, fast and can achieve decent range.
No design will scale up to decent size for regular commercial flights though, until batteries become a multifold of what they are today. When Tesla started with laptop battery cells, the energy density wasn't all that bad compared to today. Little progress.
To achieve a modest 1000 km flight, you need to pack 3-4x as much energy in the same plane. But on such long flights, you don't want to lose 2-3 hours to a an actual jet, even if the craft could get there...slowly... To fly faster, a lot more energy per km is needed. For large planes, it's more difficult to achieve lift. They NEED to go fast to get off the ground, or go any meaningful distance. A 180-seat electric jet will easily take batteries 10x as good as today. And less flammable than they are today.
What about the DeLorean from the end of back to the future? That looks pretty cool. That is just as real.
Strange that they do so much full scale flight testing and THEN go to model wind tunnel ..... wind tunnels do not work for vtol hover as they cannot deal with 90 degree flow turning. Makes as much sense as building giga factories before even having a proven product.
@@rossnolan7283 they never had a full sized craft.
That looks like a great project and visually it looks amazing.. But I'm sorry, you can't call it the worlds first VTOL Jet..

@@kingsleyzissou5881 yeah… all that money spent and doesn’t even show those tufts in action
Just install a few liberty electro magnetic generators, then you’ve got something that will fly without batteries. Also reducing weight.

@@kingsleyzissou5881 yap yap yap
😎
Just a question . I am a beginner . If we have the power of simulations why make a real test ? . Or what standards rule the number of real simulations ?
I'm a computational fluid dynamicist, I can answer that. Modeling a full body like this at high flow speeds is computationally very expensive if you're looking for little details like re-circulation zones or other phenomena that may affect flight. If you just want a steady-state calculation that can produce a ballpark estimate of lift and drag on the body then yes, you can do that. These guys are interested in the little details affecting flight dynamics. It is possible to simulate that but again, it's computationally expensive, and even still you always want to validate your CFD or at least compare with experiments whenever possible. Hope this helps.
It looks so great on videos...
@kingsleyzissou5881 HI, I am currently a student in the adjacent field of MD simulation and doing more of a wet lab work. I am interested in looking at finate element analysis for large proteins (or cells) as a pet project. I have tried blender -> sti -> open foam -> paraview pipeline. But I haven't looked in depth into the accuracy of the result, nor do I understand how to interpret the results. May I ask your opinion on FEM, openfoam (or other CFD tools), SOTA/current microscale modeling, or is it worth pursuing?
@@ngroy8636 What specifically are you trying to model about the large proteins? OpenFOAM is a finite-volume tool, so it's not really the best code for doing stress analysis.
When it comes out to the market, I hope it runs on hydrogen and an electric version

Be sure to check out Lilium’s share price and Nasdaq valuation :-)
Good job 👍✌️
