Lilium Jet hits targeted maximum speed for the aircraft: 136kt

Proud to officially announce we’ve hit our targeted speed for our tech demonstrator Phoenix 2: 136kt (250 +km/h, 155 + mph).
This is meaningful as our target cruise speed at sea level for our confirming aircraft for will be up to: 155 mph / 250 km/h.
Our tech demonstrator hitting this target helps us to demonstrate stability and controllability of the aircraft and control software also in high speed and helps us towards certification of our conforming aircraft by validating our models in the high speed regime.
Flight details:
Flight Test Objective: Achieve top speed after full transition
Aircraft: Phoenix 2 Technology Demonstrator
Pilot: Remote
Location: ATLAS Flight test center, Spain
By popular demand, here is the full flight with basic flight information including speed data: • Lilium Jet hits target...

I don't, at least I don't believe in the promised 7 seater when they can't even fly for 15 minutes with a single person on board right now! Imagine this with 7 people on board over at least 50 km or more (e.g. from a city to an airport), no battery can deliver enough power for these small ducted fans that need to run at crazy RPMs because of their ridiculously small surface. But here with nobody on board, just the weight of the batteries as a first demo that this thing can do true horizontal flight, that is a good first step, which they desperately needed many years ago. That concept looks cool but is not practical for at least another decade to actually do what they promised to deliver. I think some local RC model flying clubs have capable people who may be able to build something like this from scratch in a year or two if they work full time on it. I really wonder what they did with all these hundreds of people and hundreds of million € all these 7 years or more? They may have spent a lot of money on hiring expensive people from Airbus to make their project look legit with their names on it, so that investors with less aerodynamic knowledge as me may trust in Daniels cool looking dream. Please give this thing much bigger fans, which will require redesigning the entire concept, cut it down to 4 or less passengers and make it actually happen ASAP if you want to get on the bandwagon and survive, else you will never make it out of the financial hole you have been digging yourself in.

Lilium should only release basic facts to prevent the rumor mill. For instance if Lilim released footage of noise readings of an early test bed designed purely to test hover even though the ducted fans didn't have nozzles or anechooic liners and other noise reduction methods some self proclaimed analyst would misuse it. Likewise with battery SOC. We now have batteries with 12X the 600 cycle life in the labs. These are complex engineering projects and elements are tested bit by bit. -Besides these are propriety projects and the know how is property . Lilium investors have invested hundreds of millions in test beds and a flight test campaign to learn this information so instantaneous power draw and SOC gives huge amounts of information an competitor can use to get a design point.

Congrats! I have a technical question: Why is the upper surface of the engine cowling not curved like the top of an airfoil? There seem to be a lot of flow separation going on, with a more curved upper surface + some vortex generators perhaps the total lift may be increased and the drag reduced in the transitional phase.

[@Ikaros---]

probably because it's optimised for forward flight. having a curved surface on the cowling would increase performance at high angles of attack but would create a higher frontal cross section at low angles of attack. Considering takeoff and landing are probably going to be a small percentage of total flight time, it might not be worth it.

[@Jet-Pack]

@@Ikaros--- Correct me if I'm wrong, didn't they already travel at cruise speed in this test? There still was a lot of flow separation happening, even at that relatively low angle of attack. Especially when power is limited, i.e. though battery failure or electric power interruptions it could mean a few extra Newtons of valuable lift.

[@Ikaros---]

@@Jet-Pack at 1:45 to 1:55 you can see the optimal flow conditions for both front and rear wings at cruise speed, seems pretty stable to me. while transitioning to hovering the flat surface could act as an aerobrake, making vertical landings a lot easier as it requires less space to decelerate. Any extra lift you'd gain from the cowling would only be effective during this transition period where the engines are pointing around 45 degrees. This might be good for short takeoffs or during a sudden loss of power, but would reduce overall range at max cruising speed. While in vertical flight at around 5:00, you can see there is stable flow around the cowlings. adding an airfoil would possibly affect the intake air flow. The flat cowlings should provide extra thrust in this mode like a high bypass turbofan, compared to airfoils which might disrupt the thrust vector by curling air around the engine and into the exhaust.

[@louisvanrijn3964]

Indeed , we see a lot of separated flow on the canard. Not bothering about trust, the drag increase is a point. I tested the effect, see : kzbin.info/www/bejne/eZ-6lHScesp4nac With attached flow the glider sinks 1.3 m/s. In partitially stalled condition : 4 m/s. Three times the drag is generated by a 50% separated flow. I estimated that the stalled canard (in most of the flight conditions, except full speed flight) reduces the battery endurance with 25%. The upper lip of the canard has to be bent down (droop nose), or equipped with vortex generators, as demonstrated.

[@glueautomation-solutioneng3609]

Good question. I believe the cowling is optimised for engine airflow. Not lift. The front part of the wing provides sufficient lift.

[@simonbaxter8001]

Nice flight! Be interesting to see the glide performance in forward flight if those fans stopped (i.e. as a safety case in the even of power loss) ...

Failure mode: loss of thrust. Or worse, un-commanded thrust. I'm sure they've looked at that. Loss of thrust on 1 of n engines on port or starboard is the real question.

Just having the noise turned down or muted in videos doesn't tell us all that much. I agree that it is likely to be obnoxiously loud though, and that will be a major problem for their widespread adoption. Even regardless of that issue, I'm skeptical of the "flying taxi" concept, something that has been proposed and discussed for many decades. This new class of vehicles makes it a little more plausible from a technical perspective but I'm still doubtful of it's feasibility from a regulatory, safety, cost, and noise perspective. More what I anticipate this and various other similar vehicles currently in development doing is replacing helicopters in some functions, as they have some advantages over them. Things like search-and-rescue, medevac, military, and like you say executive and rich-person transport.

Why is this impressive? Several non commercial short range aircraft out there flying for the years now.

[@farrie201]

Thought this was het clickbait video from the thumbnail but im pleasantly suprised to see its real!

[@nippon2003]

What a flying art. Thanks for creating this spectacular aircraft !!! This video is extremely motivational to me. I want to spend my life to fly air/space crafts that I worked on as design engineer. Im planning to take engineering major in university, take courses+self taught other essential skills and team work experience in engineering then gonna try entrepreneurship and hopefully go to flight school. I’ve started as a toddler with a pen, drawing flying machines, making paper models… We did not born with wings but we reached altitudes that no birds could have imagined. We born as aviators !

[@CyberSQUID9000]

Amazing! Seems like alot of torque on the wings when the edf pods move , wouldn't be much fun in bad weather but I'm guessing. Could you use truss braced wing design similar to Boeing's ?

[@Shadowhurtz]

I love how you can see it hit cruise speed as the streamers all become super stable

[@sammyspaniel6054]

You guys are checking all of the boxes. Love it!

[@SAMZIRRA]

I am just a random viewer imploring you to share this awesome video with everyone, this is top notch❤

[@rihardsgrislis]

Well done! 👏🏼 Some screen information like speed, altitude would be great for these demo videos. Something similar to SpaceX launches.

[@rcnitro001]

Well after looking at the full video is see that the surface I thought was flat is actually open. Nice build.

[@SAMZIRRA]

Well the UFO phenomenon makes quite a bit more sense when you see something like this :) This is really cool whoever made this. Video is great too! No talking, just wind passing by, love love love this video!❤

[@sparky3713]

I saw a version of this a Osh Kosh a few years back. All they would do was a take off and landing. Glad to see they are improving. Cool design.

Pros to mister Remote who has done an amazing job risking his life piloting this Lilith Jet.

[@compassft]

I am following Lilium Company till its birth (many years ago, isn't it?) and I am glad to see they are getting closer and closer to their objective....let's hope they will take into account my fidelity and will consider to make me a discount when I will purchase one of their jets 😆

That landing was the stuff of Sci-Fi visions. I'm here for it!!

[@andrewking6604]

Thanks for the uninterrupted ( without any stupid music ) views if the flight. Well done

[@cotneit]

Designers: How many engines do you need to fit on this thing? Engineers: Yes

[@Josh-99]

This is our flying car, right? VTOL takeoff and landing, easy to control, quiet, two person capacity. The learning curve between this and a fixed-wing aircraft is DRAMATICALLY less just on account of not having to learn takeoff and landing maneuvers. Also, VTOL capability means you can set down almost anywhere in an emergency. I know we have along way to go still, but I see technology like this as bringing aviation to the masses.

[@frankyboy1131]

Capacity unknown, range unknown, speed 136 knots (as they released themselves), longest flight shown about five minutes... Well, judge yourself.

[@Josh-99]

@@frankyboy1131 Uh, yeah. It's clearly a prototype and not ready for mass production. There's all kinds of practical and legal impediments in the way, obviously. But this is how we get to great societal shifts: rough starts and small increments. Go take a look at the plane the Wright brothers used for their first flight, as an example.

[@JohnnyWednesday]

Well done! it's a very cool aircraft - I hope testing continues to go well

[@justindastar]

i'm more impressed by the size of those fields. the scale of farming is insane.

[@octavicolom4562]

That is part ofsouthern spain where 25% or more of the olive oil in the world is produced! It is quite an experience to drive around

[@dointube2]

WOW! i'm so amazed that there is such a large flow separation on those canard wings during the flight. Amazing to watch where the flow sep occurs on the rear aileron/engines also.

[@danielv7983]

Seems to me like the aircraft not conpletely balanced, i.e. requires additional lift from the canard jets, which causes the aoa of the jets to exceed bounds inducing separation..maybe a more bulky low pressure side/add some nozzles in the leading edge to create additional coanda effect locally? Or adress the balance..

[@joham8179]

I like the squishy things, I think they look neat! great design choice for this aircraft, I wish commercial planes would add those as well to add a little spark for the eye

[@rstats2127]

Wow the airflow on the wing was rock solid

[@Clarence_13x]

I like how you can see the transition between laminar flow of fixed wing flight and turbulent flow of multi rotor flight

[@watchguy7986]

Nice! I love aviation hobbyists. Keep up the good work and the dream, looks a bit rigid. Not bad for a garage build prototype! Good job guys 👏

[@watchguy7986]

@@sg-yq8pm wow…… from the look of their rig they don’t seem to know what the fuck they are doing. They left about a 3 or 4 hundred worms or strings on the plane. That is not very aerodynamic. You’d think they’d wipe that shut off you know what I mean ?

[@Nill757]

@@sg-yq8pm Expensive hobby then. Has no possibility of commercial certification with this range, this altitude ceiling, this noise level. What they do have are buckets of green money grants, from people who profit from “look at me I’m boldly funding green something”.

very good concept with safety build in, due to several engines in each spot

Its so satisfying seeing all of the telltales go straight

[@o_manam]

I've never seen an airplane wing with telltales on it, cool! What an amazing aircraft.

[@arthouston7361]

First, we need a cool name for those thrust sections. Engerons? Aelerets? Flets? Throds? Motorons? Second…the yarn makes for a great lesson in how angle of attack affects air flow over a wing or control surface. The turbulent separation is as obvious as the smooth laminar flow. I want to see how those moveable parts are being controlled!
