Test flight Oct 29: Combined inputs maneuvering flight
Вставка
- Опубліковано 7 вер 2024
- We’re continuing to expand the envelope with our 5th generation demonstrator, gathering data with every flight. The focus of this test from Oct 29 was a combined inputs manoeuvring flight with a 30 degree angle of bank turn while descending at 350 ft/min.
This looks like the beginning of a great revolution in vertical lift avionics. Amazing 👏
To you all at Lilium, let me give you another perspective of what your hard work is doing: When the Concorde retired, it was the first time in my life I felt the industry was taking a step back as, contrary to what had happened for decades, decades and decades, there wasn't anything more innovative, more advanced in Aviation to look forward to. This project of yours, as far as I am concerned, has relighted my admiration for the Human Spirit, in what relates to conquering the skies. It might be a small, apparently insignificant endeavor in the grand scheme of the industry but it truly encapsulates the wonderment of amazing things to be. Congratulations to you all and keep up your great work.
Well said, sir.
Because all of the aviation advances have been inside the aircraft. Not easy to see, but the advances in technology have continued. Just not as obvious because you can't see it. Cleaner burning ngines 70% quieter, and 30-40% more efficient than a 757! Computers, fly‐by‐wire, flight envelope protections, runway over run protections, curved precision approaches, improved auto land capabilities, longer ranges etc etc etc. The technological advancements in the years since the money-losing Concorde was retired have been just as exciting as the years the Concorde was in service.
The Concorde was a failure from the start: too loud, too ineffecient, too expensive. It only found a second life marketing to the very wealthy, then crashed and burned.
This project will not revolutionize flight. It will be yet another small private plane destined for a tiny market of rich people. The world really doens't need this.
@@MoraqVos I hate the fact that the world needs millionaires and especially billionaires to fund their unique forays into the future, but we DO. Such things are beyond the ability of government bureaucracies to even agree on them, much less successfully bring them to fruition, and so uber-rich mavericks like Musk, Bezos, Branson, Allen and the like are needed to "Just go for it" using their own nation-sized bank accounts for financial fuel.
And you are absolutely right about the Concorde. I used to do some software work for an executive for a massive gold-mining concern, and he would travel back and forth to Europe on the Concorde all the time. He said it was unusually cramped inside and a bit uncomfortable. But don't worry: I immediately called the Red Cross to meet him at Charles de Gaulle Airport so they could fan him down and replenish his champagne.
Apparently, they got there just in time.
Impressive looking demo. For those wondering about power requirements, it takes a watt of energy to lift a kilo one metre, so in the absence of any lift from alternative sources, the aircraft will be consuming its’ weight in kilograms, in watts per second, just holding a vertical position clear of the ground. Double that figure for every metre climbed vertically and it soon adds up to a lot! Then there are the losses due to electrical resistance and fan inefficiency, so perhaps add an extra 25%. Horizontal flight with lift provided by the wings reduces the power requirement, but drag forces increase by a factor of four every time the speed doubles. So flight at any speed much over 160 kph will become less efficient due to power requirements due to drag forces overtaking the benefit of lift from the wings. There is a sweet spot where horizontal speed and wing lift are precisely balanced to minimise power requirements. That can be adjusted to some extent by aerodynamic reshaping but the fundamental limit will remain of how much power the batteries can supply to lift the aircraft a given vertical distance for a given period of time.
Maybe look up the difference between energy and power
Just want to say that I have been following you since the very start and you are the most most exciting project on the market right now. Also the sound of the engines is like something from a sci fi movie!

It’s beautiful 🤩 The best VTOL ever!
Hell no. It is infact really inefficient if you compare it to competing projects.
@@stylefreak2344 It will have a longer range (250km) and higher speed (300kmh) than almost any other. The engines are less efficient in hover but far more efficient in cruise. The transition from vertical to cruise and back again inclusive of landing/takeoff will only take 30 seconds.
@@williamzk9083 250km including all the energy for going to the alternate plus the contingency plus the 30-45 mins final reserve? You cant just use all your "fuel" to get to your destination
@@ikermunoz6947 Lilium in their website say they have made safety and operating allowances in their quoted operating range of 250km. The VFR 100nmi divert and 30min-45min reserve used for light planes won't be needed for eVTOL because an eVTOL will have easily half a dozen alternate vertiport landing pads the size of a tennis court say 100m, 1km and 10km away. It doesn't need to find a 1200m landing strip.
This is the best engineering technology and design I have seen so far for evTOL category. I salute and give congratulations to your CEO, engineers and workers behind this amazing aircraft and one day the world will be populated with this environmentally aircraft suited to planet earth. I am one of your investors. Peace and cheers!
Now that's the good stuff!! Congratulations!
Also, special thank you to whoever decided to include the flight data and original audio, that made the video extra special.

There are many benefits of using electric ducted fans; quiet, more efficient, placement over wings adds lift, easier to place multiple smaller fan units than several large engine driven props. I would buy one if able. The large and airy cabin is a bonus. Doesn't look or feel like being stuck in typical fuselage. There is a major move in auto industry towards multiple electric drives, one per wheel. Same benefits as the Lilium.
Beautiful project in deed Keep it up . Looking forward to seeing more of it soon .
Great job 👏. Take your time and master every step. 👏

Outstanding!!! 😎😎😎😎I know you guys are working very hard! Congratulations, looking forward to 2024
Thanks Rob, appreciate it.
Anybody thinking about investing in this should take a look at the history of the Moller M400 Skycar.
that was one guy who had a great idea and tried his best not a company with 600 talented aerospace engineers
@@dalequammie937 The Moller Skycar was a brilliantly designed vehicle to extract money from naive investors. As such it was spectacularly effective with some accounts suggesting it generated as much as $100,000,000 over the lifetime of the scam.
The Lilium drone is just a repeat of the scam but with added media hype.
This battery powered drone will never carry a practical payload over a useful distance.
By all means invest if you have confidence but be prepared to lose your money as you certainly will.
Love the kestrel watching the plane giving it, "Yeah whatever! I can do that easily!"
Everytime I saw it I fall in love😍😂
That's amazing!!!
Finally, a ducted fan aircraft that is not ugly. Impressive.
Kinda neat. It'll spend more time charging than flying, that's for sure.
Changeable battery racks are a must 👍
The point of difference with this craft is that it transitions into normal winged flight and the fans are used for forward thrust only when underway, this is way more efficient than being held aloft by fans the entire time.
@@mitseraffej5812 VTOLs without wings are gimmicks.

@@0Turbox they might eventually
Didn’t they work on a 2 seater at one point?
@@nikobelic4251 Doubt that. Maybe in the distant future, after their fleet was successful over several years. The 2-seater was just a smaller prototype. They are, even with a 7 seater, very expensive to travel with. At least here in Germany, were we have to pay over .30 Cent per kw/h. And that's Euro Cent. In the US, were you can load with .07 US Cent, that's cheap as hell and could work in general.

What, this remote controlled drone?
Great idea for a planet that doesn’t have any wind.
Oh look, time for an upgrade from my Mavic Pro to this. Knew it wouldn't be long!! Awesome stuff, I will beta test for you Lilium.
The silence of the aircraft is awesome
This looks already promising. Congratulations to have achieved this step. Of course, many more will need to follow, like aerodynamic flight. But I trust you will be successful.
There's quite a lot of bounce when it lands. Hopefully it can have lots of give in the suspension in later versions for a very soft landing. Incredible work anyway! Congrats
Yes, you should install much, much longer suspension travel. i like this plane a lot !!
I wonder, when can we see it transition to aerodynamic flight? That is the single most important thing for a vehicle of this kind along with bringing the noise down. Without proper aerodynamic flight the endurance will be terrible.
Hi Max, good question thanks. We recently announced we are moving our flight test campaign to Spain where we will have a larger airfield and more reliable weather to expand the flight envelope into cruise flight and transition. Aiming for early to mid next year so watch this space.
@@LiliumAviation Excited to see your next step forward! I personally hate moving, but it sounds like it’s for a great cause. Hopefully it won’t be too bad.
@@LiliumAviation why not move somewhere in the states like Nevada? Plenty of space
@@josephmelton4721
It is a german company and spain is nearer.
How will it perform with high winds?
Yeah. Like this is the solution to our transportation problems.
This will literally change the world
Would like to see it flying aerodynamically. All the flights we have seen are thrust supported just like a regular drone.
At >40kt airspeed I would expect at least some aerodynamic lift.
How do you know you're not? I can't imagine those banked turns being non-aerodynamic?
@@WillBravoNotEvil Given the angle of attack of the engine sections of the wings doubt there is laminar flow to provide lift. And sure the stall speed is for that kind of airplane configuration must be over 60 knots, that is 100% more lift that you can get a 40knots. The airplane is pretty much flying because of the trust of the engines and not on the lift provided by the wings, and you can bank by adjusting the thrust just the way any drone does.
@@hernanechaurren7986 this thing is a total scam intended to do nothing more than separate investors from their money.
@@homomorphic Would not say a scam, but it doesn't seem to be a commercially viable project.
Daniel and Team,
It’s simply awesome how you prove the pundits of the aerospace industry wrong!
We had an office next door and provided you some office furniture for your early team. Getting on the pre-order list wasn’t an option though, due to a capital increase in our own startup 😀
Really like the plans with Azul, really solving problems in BR…
Hi Clemens, thanks for your support and just as importantly, thanks for the furniture! Keep well.
Who and what did Lilium prove wrong?
Congratulations, I was skeptical at fist but it is so quiet and that alone is a massive win 🏆
Where did you got the data from? How much more silent is it compared to a electric car?
by the paper states a calculated an excellent low noise of 60db at 100m
@@kentonian Thank you for the data. Excelent is relative. A VTOL is only usefull if you really want to fly in the city... so I expect much lower distance than 100m. And the 60dB are allready higher than the allowed traffic noise in german cities. Hence VTOL will be in addition to usual traffic this is a no go.
@Will Swift Insulating all homes will take decades. And there are people who sometimes leave their homes. Therefore I really hope that you are wrong.... also because of the environment. We will struggle to produce all the needed engergy by renewable resources, even if we don't increase the number of flights. Flying is always less engery efficient than a rolling vehicle.
Very stable VTOL, impressive
Lilium is the future !

@@LiliumAviation 🙏
People have many concerns about this new form of transport. It is good to see Lilium address them directly in the comment section. Keep it up
@@LiliumAviation what is the price of 7 seater jet
@@LiliumAviation Have you thought about using small rockets that activate in case of an imminent crash, so essentially like a virtual airbag for the entire aircraft? If it falls down from the sky, the rockets could activate before it hits the ground and dampen the crash enough to be able to walk away.
@@jimj2683 lmfao🤣
beautiful machine!
if you look at the time, they only manage to fly for 2 min....compare to Joby 1hr and 10min (152 total miles). They have their investor presentation saying the aircraft can do 150miles. This company is a scam honestly.
DO A BARREL ROLL!!
It would be nice to see that it can perform more complex maneuvers in case it needs to do so during an emergency....maybe not a barrel roll, but at least a cool dive or something.
Those small diameter props have poor efficiency because they have to turn so fast. Sure, a ducted fan can give 10% more power at slow speed, but you never seen one on an airplane because they become a big drag as speed increases. Compare this the the Kitty Hawk Heaviside.
Try adding the area of all of them, the disk loading drops enormously
Nice, but how about a video where it hits a decent speed with the engines fully horizontal. Seeing that would be awesome.
Give it some time ! Expanding the flight enveloppe is not done in a rush.
@@SuperYellowsubmarin They’re DEFINITELY not in a rush. They’ve been doing flights exactly like this one for over two years!
i tell you what: they can`t do that right now, otherwise someone would have seen it.
@@bryanlallen Exactly. The P.1127 Harrier precursor was flying properly within 7 months of testing commencing. But it admittedly it was years before the P.1127 became a practical military aircraft.
Hi Michael, thanks for the comment and it is something we are working towards. We announced this week we would be moving the test campaign to Spain where we have more reliable weather and space to expand the envelope further. Also as @AeroGarage said it is not something to be done in a rush. Thanks for your support.
“I’ll take dead-ends in aviation for $1000, Alex.”
It's going nowhere until great advancements are made in battery technology. That may be 50 years from now.
No Shit. That was hilarious. Aviation Goldberg projects. Can't believe someone put money into this Shit. It can't go anywhere or haul anything. Until there is a gargantuan increase in energy density of batteries, electric aviation is a joke.
@@w8stral Here is another " Start Up " Scam. I think the flight time on this one might be 2 minutes,?
ua-cam.com/video/FzhREYOK0oo/v-deo.html
Man your high school guidance counselor did you dirty huh
Wow. Future of transport is being made. She flew beautifully. Congrats👌👏👏💪🤗
Pretty cool. It flies!
Ya baby!.....LILM; almost a $2 handle. Looks like the VCs top ticked it!
Please show us transition to horizontal flight - you claim the goal will be 300mph mannes flight in a 7 seater = 267 kts, so 40kts is tiny fraction of that with how many people on board? after how man years of development, nearly 7 years?
What happened to the airflow meter between 0:32 and 1:32 ... for one minute a tenth of knot constant airspeed? Isn't it super critical to have a real airspeed meter that works during the entire time for the flight computer to calculate the manuever? Do you use non redundant hobby grade components? Even my cheap Chinese airflow gauges work more reliable!
Looking forward to seeing it live!
All the test flights have been capped at 40kts, why have we never seen a full transition to wing bourne flight? I can see the current test area isn't very big but there are plenty of places you could take it to allow it to stretch its legs.
Just looking at the surface area of the wings and how absolutely terrible the parasitic drag appears to be, I think there's a reason we aren't seeing that. It's a neat toy but I can't see how it would ever be usefully efficient to operate for more than a cool demo around an airport.
Some hopes!
Is that real sound volume? How far away was the camera operator? Unbelievably quiet!
Hi Yuriy, thanks for the questions. Yes it was audio recorded from the day, at take-off the camera was 130m/142 yards away and at landing 100m/110 yards.
It has 30 ducted engines and quiet. 👍
How can you tell from a recording how loud it was? You don’t know the volume settings of the microphone or video editing software. This might have been 40dB or 160dB. You can’t tell.
@@hepphepps8356
There is also a camera with mic on the cockpit and you can hear the wind noise, wind noise can't be 160dB.
So yes it was really quiet.
The smaller the fan, the quicker it needs to rotate, the louder it is. I can't imagine this being 'silent'.
Local reports are coming in of actual UFOs. Authorities are agreeing that temperature inversions in the area are compounding issues with Swamp gas and refractions in car windows from oncoming cars with defective high beams.
Lol, that is a beautiful aircraft! Very crisp control in Roll.
call it, One More iteration of a SILLY IDEA.!!!!!!!!
Is there any TestFlight going full speed / really using the wings ? The engines seem to point down always.
>all the armchair critics: can’t even build an IKEA table
> HURR DURR WHERES MY AERODYNAMUC.
That blades need to transition to full horizontal than partial otherwise it’s going to act like a bird scoop in bird strike scenarios , plus I would also be a little worried about ice buildup with that design as you know it’s going to reach 5000 ft in a number of countries
science understood nothing until there was nothing left to understand😂
Well done! You are clearly in the lead of the pack at the moment! Keep it up!
I want to see it fly at least 100 miles even in good weather, then recharge, take off again and fly back. Only then it is worth something. Ohh and another thing... it must have at least 50% battery remaining at the end of each flight.
On repeat. So beautiful
Thanks Brandaan, glad you like it.
It sounds like 50 Dyson hair dryers blasting away. Hmm...need extension cords.
Why are these cuts in the video?
Fantastic!
That looks bloody dangerous ! So it has an endurance of a few minutes with NO payload at low speed !
SOME ACHIEVEMENT !
I wonder how it glides with no power. Maybe this eventuality is not considered probable or is designed for. Must be a lot of drag in both vertical and horizontal thrust vector positions. When the thrust vector is set horizontal, the impeded flow through the fan blades would lead to a slow down of airflow over the top of the wing and result in an increased pressure over the wing top-side - not good for lift, or drag. Maybe this is not enough to prevent a useful glide to safety however.
It will hang in the air in the same way a brick does.
No words, unbelivelible.
That amount of EDFs is so inefficient. AMP draws is probably off the charts with current pack density they are using
very stable...great
I just want to know the decibel count on this
Average speed and range? I assume the batteries get drained pretty quickly?
Average range is 150 miles at around 150 mph.
The 7-Seater Lilium Jet will have a cruising speed of 175mph and max range of 155+. In regards to the batteries yes hover drains them faster, but the aircraft architecture is designed for regional flights so we will have a highly efficient cruise (approx 10% of hover power required). Our CTO explains it really well in this article, if you're more visual then skip to figure 3b - lilium.com/newsroom-detail/technology-behind-the-lilium-jet. Thanks for the question.
It seems to me that having the minimum time and altitude in hover loss for best battery life, so that, where space allows, using a more "STOL" takeoff and landing flight envelope will allow best possible range, or minimize battery charging time, increase battery life... I lived about 20 km from Lilium, would loved to have taken part in the development!!
Nonsense. They last as long as the promotional film which is all that’s necessary.

Congratulations Lilium team. It would be great to publish on videos like this the energy output from the batteries. I understand that most of the juice is on take off and landing. Also. When can we see the 7 seater in action?
Does it come in Black?
This better be in the next James Bond movie! 😎😎😎
As i've said from day 1. This will end badly. A billion dollars vaporized.
Care to elaborate?
When can we expect to see first manned flight?
It seems there is almost no wind so it seems little unstable to me, similar to ultralight. Have my doubts about flight in bad conditions like wind and snow.
Range is everything.
Why not level winged flight? you can only do short range remote control? why not GSM long distance and autonomy so it returns to origin if contact is lost.
And is it with or without payload? from my perspective it looks like you are progressing much too slowly.
It’s the ultimate manscaping tool:)
This should be a hybrid craft. Have an engine driving a generator with batteries only for use in case of engine or generator failure. Just have enough battery power to conduct an emergency landing which is made vertically. A failure when in winged flight and most of the descent would be under winged glide using little to no battery power.
With windmilling fans excess altitude or speed could be used to add charge to the batteries just as restorative braking works on electric cars.
This is a very non efficient design with the tiny ducted fans meaning a small amount of air at a high velocity. It also has a traditional aerospace build which inherently brings the traditional high aerospace costs.
Yea, umm, try adding yep the area of those fans.
Not to mention, no ability to glide or autorotate. A traditional helicopter is way safer, and probably way cheaper.
When are you able to do the first flight at max range?
Best car for future
The Belkans are at it again
Does this thing contribute to peace?
Wahnsinn! Drücke euch so die Daumen! Es wird! 👍
The best eVTOL concept together with the most speculative Jetoptera.
I'd like to see how this design deals with the failure of a bank of motors/propellers when it's in any mode of flight, but particularly when transitioning between forward and hover.
The multiple motors are are redundancy.
@@skateboardingjesus4006 that doesn't address my point. What if an entire bank of motors fails? How could that happen? Simple, you get a break in the power that supplies electricity to those motors - a broken wire, loose connector, etc. Say that can't happen? then you haven't worked on real life aircraft (speaking from experience as an aerospace engineer & pilot who has maintained real life aircraft).
Helicopters auto-rotate as a redundancy to maintain flight if there is a loss of power. But there is a zone of performance where auto-rotation is not practical because the lack of horizontal speed and altitude of the helicopter make the physics of auto-rotation not work. If you're in that zone of the performance curve and you lose power, you're gonna crash, period, full stop, there's literally nothing you can do about it. The only way to mitigate that crash is structure (like landing gear or skids on a helicopter) designed to absorb that impact.
My question is: how does THIS design handle that failure mode, when it's in hovering flight close enough to the ground with insufficient horizontal velocity that the wings won't develop enough useful lift to glide safely to the ground in the event of propulsion failure.
The answer can't be "the motors are redundant." What if there is a total power failure? (analogous to a fuel powered engine running out of fuel - don't say it can't happen, cuz I guarantee it can) - commercial airliners have had all engines fail when there was supposed to be redundancy, but even they were left with some ability to glide. Let's not even get into the mathematics of the probability of failure of multiple components vs a bank of connected components.
@@sthomas6369 I'm referring to each motor being independent of each other, where the loss of a couple can be compensated for. That's assuming they also have physically separate power source connections? If it suffers an event of multiple motor failures, it's screwed. The altitude is laughably too low to transfer vertical momentum to lateral gliding flight during a failure, so it's screwed. I imagine the geometry of the wings trailing edge and motor placement, is to help with laminar flow under powered flight? If so, it's probably not great in glide mode? I also can't imagine it's very efficient either, and battery energy storage capacity, isn't even close to making this have any appreciable range. Certain aeronautical applications of electric propulsion have promise, but not in this configuration.
Parachute and vomit bags
thats my point. the whole project will be a short fun if just 2 jets out of 1000 crash the ground due to a failure of a motor or something else. and this do not just stands for lilium.. I mean that whole e-motor air-taxi party
