it wil never stop lol

Yet still it feels like this plane is ancient.

This is a pretty weird statement

2022 and we have ugly planes like this.. sorry but not sorry.

china's engineers : we just steal.

Impressive? What is impressive about it? Thing looks dangerous as hell. You do realize we've been flying for over 100 years? Tell me what is impressive about this, I'd like to know. It looks like the gocart of aircraft. If they could make it safe(where one shorted wire won't kill you) then it might be cool to have(but I'm sure only rich people can afford it to drive around their golf courses) . I don't see this as being impressive. Maybe there is some aerodynamical achievements. Is a real person in it? What happen when you add a 200 lb human? How long do the batteries last?

@@jsmdnq You know they're working to find out all that? Too much people underestimate the work I think.

@@91djdj Well, do you have any knowledge of electronics, aerodynamics, and such? Cause, I mean, if you don't... say you never even solved a simple differential equation in your life... then how could you possibly know if they are working on anything legit or not? Maybe they are and maybe they are not but if you yourself don't have some minimum level of knowledge required to judge what they might be doing then you can't possibly know, could you?

@@jsmdnq Same goes for you. You don't know what they're doing in their facilities. I am not acting like I know which projects they make. I am just saying they're probably very busy.

@@jsmdnq "The incredible engineering behind the Lilium jet" kzfaq.info/get/bejne/kNaUd7xj16rXfH0.html

And the efficiency figures. Straight level flight power consumption will say it all.

Exciting… not at all

@@tonka5 ???

Very exiting... a remote controlled drone just took off and did a little traffic pattern... Milestone stuff... invest more, buddy!

It was level flight it was going forward and the wings were level did I piss something ?

helicopter with extra propeller and complexity

@@danielhipp5541 He ment level flight with the engines in fully raised position and the Wings generating the whole/most of the lift. Airplane mode if you will. That way the Lilium vehicle should drastically reduce the power consumption and be superior to the other personal electric copters.

@@quantu1112 ok yeah I would like to see that also with people in it looks amazing 👏

Sci fi? Ever heared of the Harriër?

Every Chinese DJI drone is more stable than that

Yes, I can do that with any DJI drone... But can it carry passenger further than 5 Miles in good weather yet?

well, i would not call 86km/h fast but i am sure it can fly much faster than that. 250, 300? the amount of control looked great. very stable.

So that’s what those are. Thanks

What else did you expect?

@@avigator some air bleed from leading edge louvres at high speed high pitch might cost less in lift than they do in drag

Not sure that’s „good to see“.

@@andreask9382 Ja, It seems to me that this much turbulence is lost energy.... but, maybe not much, overall?

...and thus lacks the efficiency required for today's battery technology.

@@yt3dkraft Exactly...it's just hype

@@yt3dkraft ducted fans are far more energy efficient than traditional propellers. Try again Einstein

@@mastermnd22 Ducted fans have a little advantage but it does'nt even compensate for the additional weight of the ducts. So, you still have a unfavorable relationship between propeller area and propulsion weight which means bad efficiency. Simple physics... It will take still a lot of time until battery technology will catch up with this disadvantage.

@@yt3dkraft while i agree the battery tech is not currently capable of long distance flight. You are far underestimating the capability of ultralight ducted fans. The ducts are made of paper thin carbon fiber. They weigh absolutely nothing. And the advantages far outweigh the weight.

@Very Stable Genius Nope. There are 50 dollar drones that fly on vectored power. Aerodynamic flight has to deal with the uncertainty of aerodynamics, turbulence, wind shear, etc, and short time notice in condition changes, not an easy feat.

I guess they are making sure that all the systems for reversal to vertical flight are in order for safety to be assured. Am sure we shall soon see not only a level flight from lillium, but one with passengers on board as well. That is where they should be by now, really late in fact. Considering that Ehang, Joby, Evolo etc have had uncountable manned flights.

@@pauldatche8410 thats possible, a Roadmap would be interesting!

Yeah, they're practically idling around the patch right now. 84 km/h is not really getting any lift from the fixed wings. A Piper Tomahawk with a lot more wing area would sink like a rock at that speed. Projected cruise will be about 280 km/h as I recall. Focus right now is perfecting the inefficient parts of the flight profile - T/O, transition, turning , hover, landing -- before getting into the part of the envelope where this design really shines. Folks like Ehang and Volocopter are shooting for short hop, lower speed profiles (downtown to airport for example) and are more efficient in up/down/hover and less efficient in level, higher speed flight. Lilium will be less efficient at the ends of the flight profile, but much faster and more efficient where they expect to spend by far the bulk of the time -- level and fast with the wings and not the vectored thrust doing all the lifting. Sure is hard to wait for them to get to that part of the testing, though.

Level flight is easy to manage once you can manage hovering and transition. That's what I learned in a helicopter introduction flight. I could easily take over and fly the heli on level flight. But coming to a stop and hovering on the spot was a totally different game. So the instructor told me that that's what I'm going to do most of the time should I decide to become a helicopter pilot. The turbulence indicators on the engine also indicate that this is the most challenging phase to control. You don't have that challenge with drone type lifts. But then you also don't get the efficiency in level flight which will be most of the journey. I guess that's why Lillium puts all the efforts into mastering this phase. Everything else will be super easy then.

Right thanks for chipping in guys, good stuff! Sounds logical indeed. Since the commercial result depends on getting that high efficiency in level flight I do hope they have the windtunnel test results to prove that phase works

Exactly, I've seen a lot of VTOL/Drone designs this is only one I would feel safe to sit in.

Other companies are catching up with Liliums business model but the overall vision is clearer at Lilium. It was clear from the start what the jet should be capable of and how it needs to look like. While the other big players are working on air taxis AND jets, Liliums idea seems much more "branded" and thorough.

But really, is FAA the elephant in the room to all these wonderful developments? Are they playing catch up where they had little preparation?

Actually it’s an EVTOL. E for completely electric. Hence the name Lilium as in lithium iron batteries

@@pauldatche8410 Might be. Startups that have to deal with so many regulations are easily playing catch up the first few years. And this is a whole new market. There is so much new stuff that pops up the regulators see as relevant.

That's what I like about the ribbons on the flaps being a real time visual on lift.

@@TaxPayingContributor exactly! Being able to see flow separation or lack of separation is awesome I’m more into car aero for efficiency’s sake but a huge fan of flight

@@NickBDesigns practical, tangable, real life data interpretation is more intuitive than and 3dcad cgi

@@TaxPayingContributor yep plus is almost completely free just the cost of adhesive and bits of of string

0 kph

like the flaps are also the mini turbo fans with lots of redundancy and lift and thrust all at once .. and adaptive.. weeeeeee

Yes, I always loved hovercraft, too... Problem: They never worked

Rain, snow and higher winds - sure, but HAIL? There's no plane in existence that can take hail without damage. Not even military.

@@robbiegentle8327 like an exfoliant!

This would fall into the light plane category.....Cessna 150's dont do well in all weather, and any instructor pilot would strongly advise against it.....No light aircraft are "all weather", (that I know of.)

@@_r-a-f_ They take damage yes, but this thing would be knocked out of the sky by hail.

Not likely to happen as this is a tech test bed design, not anywhere near a final product design

Massive strip mining of the planet followed up with battery dumps leaching into the soil?

It's what the plan looks like! I wait for the certification: what license, what airfield? It will be a good plane only if there are no airfield needed to operate and the license requirement lifted (like with the drones: air law, meteorology and same basic safety; no extensive flight training; additional training for airport operations possible) This thing doesn't seem to had any safety feature which will allow to lift some requirements (full SPL, PPL, airport, parachute, no private property operation from your lawn).

@@hook86 Yeh, just like 'beyond 2000' tv show haha

Yeah I can just imagine teenagers on their phones “driving” one of these. What could go wrong

Beauty lies in the eye of the beholder. The claimed performance and range are a pipe dream with this concept.

@@andreask9382 the flight characteristics in this video are beautiful in my eye. And so I presume also in the eye of those who appreciate the nuances of flight. The specs will improve over time. The method is novel AFAIKT.

I am impressed by all you fans ignoring the ongoing warnings for years... The fun fact is: Once they file for insolvency, all of you will start to open lawsuits because you felt betrayed... But fact is: Lillium is a scam, will never transport people and you should better invest in small military drones.

@@potatojake197 looking to be the best ‘69 evah.

There is a video called "Program & Certification of the Lilium Jet with Yves Yemsi" that explains their plans in detail. Their preliminary design phase is now over and they are now starting the detailed design and testing phase.

Sell your shares and cut your losses.

@@andreask9382 because?

@@lohikarhu734 Because it is vaporware.

@@stejer211 Vaporware is when there is no product. They already have a vehicle and they’re openly testing it. You’re just a bitter troll.

no, it isn't, its just an exercise in futility, this whole concept is extremely flawed, VTOL is very energy inefficient, not to mention the electricity storage issue, consuming fuel reduces vehicles weight which has a benefit of extending the range, electric battery weighs the same regardless if it is empty or full, not to mention energy density problem to begin with the only benefit from these businesses are to the owners who pad and spruce it up for sale, that is the ONLY benefit of these sort of companies

@@dsfs17987 I agree, we should put all our efforts into making transportation as ecologically sustainable as possible. Let's stop focus on gas-guzzling personal transportation and put our energy only into things that actually contribute towards this better goal.

Software engineering is what they need now. They should work with the UK on this, world leaders in software.

My understanding is that this aircraft design is intended to be tolerant of individual motor failure. I certainly hope so, so that this is a leap forward.

@@JoeOvercoat yes. they for sure have a nice redundancy. brushless electric motors are very reliables in general and do not need maintenance. the electronic control can notice problems if there would be one. good reliable concept. especially in difficult terrain and urban environments.

Why?

@@brucebaxter6923 Because the main wing is extremely far aft and has very little lift in the first place. This thing is a lawn dart if the power fails.

@@thehobbyshop5306 Oh, so it’s just that you haven’t got a clue how aircraft work

@@thehobbyshop5306 canard looks like 4m, main wing looks like 10m, so roughly the same wing as a standard single seat glider. This configuration is roughly the same as a Routan longezy, again a very efficient aircraft

@@brucebaxter6923 What do you think about the drag from all the motors?

They chose the unit that gives the larger numbers. Impresses the gullible.

They claim 175 mph with a range of 150 miles. It's good for short hops.

You can do that if you are vectoring the trust from the wing itself. Basically you artificially create the lift the wing is losing when banking.

imagine a fidgeting human inside that weighs a lot and it probably isn't that stable.

@@johnruddick686 now imagine 3 dozen rotor blades that can easily adjust to compensate for extra weight on either side with plenty of power to spare. As long as there's enough power and the aircraft is operated as it was designed to, someone being overweight is not a problem. Flying solo makes a weight imbalance and its not an issue.
