The Lilium Jet is a marvel of engineering. This eye-catching attractive Aircraft revealed in 2021, generated skepticism among aviation experts. At first glance, Lilium’s ambitious design seems impractical for a fully electric, seven-seat, vertical take-off and landing aircraft. The associated implications of the propulsion system selected appear to make such an evtol concept impossible, mainly given the thrust required for take-off.
In fact, more than 80% of the leading evtol companies are using conventional open propellers as the main propulsion system.
Lilium, instead, has developed a novel electric ducted jet engine that integrates smartly with the wings of the aircraft. The success of this powerful technology not only will allow Lilium to achieve all the performance objectives of the flight profile, but also could help the aviation industry in the transition to affordable emission-free intercity air travel.
In this video, I will go over the 3 key innovations that make this technology truly impressive and technically sound.
This is the Engineering behind The Lilium Jet.

Hi Verne, your curiosity and the fact that you can not see motivates me to try my best explaining the aircraft showcased in the video. It is a sleek looking aircraft that is mostly white in color featuring some additional black trimming. The aircraft architecture is utilising a set of smaller wings in the front and larger wings in the rear - a so called cannard aircraft design. It is about 11 Meter in wingspan (rear) and can seat 7 people within its extremely sleek looking fuselage, which might remind someone of the shape of a shark (without it's fins). The aircraft is being entered on the left using a splitting door with integrated steps - oftentimes seen on luxury class business jets. One centered pilotseat in the front and 6 passenger seats behind. Its propulsion system is distributed along the rear trailing edge of the wings. 36 electrically driven ducted engines in total, of which 12 of them are on the two front wings and the other 24 on the rearwings. The engines are mounted in the pairs of 3 within so called flaps that are able to tilt around 90 degrees from a hover position into a forward flight cruise position using compact and strong servo motors. One special characteristic is the fact that there is no conventional tail stabilising surfaces (like a rudder) - it's all thrust vector based and therefore relies throught its full flight envelope on complex flight computing systems. The landing gear is of fixed nature and consits of one nose landing gear and two main landing gear legs that are being covered using a aerodynamic fairing structure that is likely utilised as a stabilising surface during forward flight, effectively replacing the vertical tail of conventional aircraft. The aircraft also offers a relatively spacious looking cargo trunk in the rear. I hope I have done a good job in describing this very beautiful and elegant looking all electric vertical take-off aircraft. Let me know and I am happy to clarify things further if you want! - Robert

As a long time aviation enthusiast and hobby drone builder, I've really been excited to see so many eVTOL ideas coming out. It's like the early days of aviation, where so many concepts were being hashed out. Personally, the Lilium Jet and the Blackfly are some of the most efficient, elegant, and interesting ideas IMO. Lillium is more advanced, but the Blackfly is such a simple and effective concept. Better cheaper cleaner battery tech is gonna be the big hurdle to be solved.

Great explanation. I had been wondering why they went with EDFs, but that explanation of the decision to favor cruise since pure hover is such a short time in the flight makes a lot of sense. Also the gains they get in transition due to the "blown" wing help for low speed flight. Thanks for this video!

Amazing what you have accomplished... the trajectory of consumer VTOL has changed. Electric Ducted Fans work great. Placement of fans on wings helps generate more lift in cruising mode. Lots of smaller fans are easier to place than several larger engine driven props. Lots of fans also mean redundancy if 1 fails.

What an absolutely brillantand beautiful piece of art. It's an odd thing in life how you always get skeptics, even when you showcase the most amazing piece of engineering. Somehow they have no imagination. Have worked with clueless people like this which is extremly frustrating. When you have an idea and can clearly visualise it working in your mind and no matter how simply you explain it to them, they just can't seem to grasp the concept. Fortunately there are enough brilliant engineers who team up with those geniuses to make projects like this become reality. Predict this will be the biggest innovation of the jet engine since its invention.

I think that old aircraft aviation from the war eras will become obsolete. This looks like the new technology. I also believe that this new technology should be able to glide and land safely if all power fails, I think this would be an absolute necessity . Safety first.

the pipistrel alfa electric shows that it is working. my lucky guess is, that they used conventional batteries that where available at the time of development. at that time it was around 200Wh/kg. standard in EVs is now 240-260Wh/kg. highest in EVs is almost 300Wh/kg best in low volume production is around 450Wh/kg (amprius) i suspect 240-260Wh/kg for prototype testing now. but at some point when production volume of the batteries is high enough, 450Wh/kg will be available. but for that project they used custom cells from the german company "customcells" where i don't know what chemistry the are using.

How does it/can it maneuver in a crosswind while maintaining stability? It's aesthetically beautiful, but I know what a crosswind can do to an aerodynamically stable plane on a typical day. Can this thing handle a wind gust or airflow change, i.e. crossing a frontal boundary...? If it survives safety/torture tests and has viable lift cap. and range I might be all in for this.

Unfortunately, this video is already a bit out of date: The number of jets has been reduced from 36 to 30, with 18 on the front wings (three banks of three on each wing) and twelve on the canard (two banks of three on each side). The size of each jet has been slightly increased to compensate. This was done to reduce part count and complexity and thus reduce production cost.

Primary Drawback - is simply that it is a new Aircraft that needs to be certified, but the certification requirements are all new, Because of the Energy Source (Batteries), and the Powertrain Design, (Encapsulated Ducted Fan on Flaps), and possibly a "New Flight Control" Approach, of using power adjustments for some of the Aileron and Rudder Functions! Other than that, it builds on knowledge in aerospace design, that has been collectively developed over the last 120 years! And Adds a new twist, many small vs one single large, power source! (Or, as is typical today, "Two" copies of a "Single Large Power Source" - be they Piston, Turboprop, or Fan Jet Engines! The Classic "Turbo-Jet" that has no "Bypass Fan" is seldom used anymore, in Civil Aviation.)

I upvoted but could be interesting to get to a minimal altitude to transition to a climb profile. It would still probably only be a max of several hundred feet as you could imagine that the weight of copper needed to supply the power might be of a fairly heavy gauge. The gating factor would be the max weight of the cable supplying the power that would still allow the aircraft to climb at a given gross weight.

Wonder how much further the range could be with a tether that would use shore power to get it to about 3-500 feet AGL before dropping the tether and starting the trip.

idk if you need the extra power once the wheels leave the ground. by then you have gone from 0 to whatever the takeoff speed is, which has to be done rapidly since runways are not very long usually, and there is a lot of drag while running on wheels. if you mean doing vtol then that makes more sense, but it still sounds scary. a long cable whipping around in the wind attached to your aircraft? heavy and scary.

Doesn’t matter how quiet it is, If an approved point to take off and land is allowed within a city you’re not going to also get approval to climb in motion. The aircraft will be expected to go straight up for noise abatement.

Why the speed and altitude restrictions, man just go for it!!! The propulsion system looks cool and all but I'd argue that battery technology isn't there yet. I would like to know what the proposed specs of the full size version will be. For example, a Cirrus Vision which is a single jet engine has a range of 1,000 km with a speed of 300 knots. Will the Lilium be able to be able to match that?

I believe this aircraft uses grate deal of energy and hence exhausts the battery on take-off and land. So an obvious solution seems to be why not use hard wire electricity to take off and then detach and cruse and as it can hover it can be re-attached to hard wire electricity for landing too. This should allow much longer ranger or increase redundancy factors substantially

i am wondering.. if these are going to be used in planned take off and landing ports.. could the craft be tethered to a power source to feed it the high power it need to lift off to perhaps 200 or 300 feet up and then while at hieght it could transition to horizontal travel then detach from the power cord. This could be provide either by a kind of exention cord that would detach.. or it could be connected to power source like an electric cable bus.. with the electric cable being vertical to the ground.. and as the craft lifts up.. it would gain altitude with maximum power consumption fed by ground energy supply.. then as it is at hieght.. the props would transition to horizontal.. the craft would have an extention to allow it to move away from the horizontal power cable and at perhaps 50 feet from the power cable, it would detach from craft, allowing the craft to proceed with onboard battery suppoly? This would allow it to use most of its power for horizonal flight with its wings providing most of its lift and giving it power to transition back to a vertical landing? And in case of emergency(or planned), it could still land like an airplane, reducinging its power needs for landing? and if designed right, it may even be able to glide to a landing??

If all power to the motors is lost I cannot imagine that this would glide very well once the dead engines acted like spoilers/speed brakes.

Beautifully promising innovation. I think these would be more advanced and affordable in the future if the order of the world holds... I hope cleaner and safer energy prevails. Although calling the propulsion "jet" is a bit of misnomer. Electric fan would be more appropriate.
