Ah, that would be the dreaded 35 motor approach. Even scarier: two motors out on the same wing, so now down to 34 motors.

Er its called ballistic recovery parachute system as fitted to many LSA and larger aircraft. Cirrus C 172 C 150 etc etc.

Been around since the 80's and so far used successfully about 250 times.

Even works when the wings drop off obviously.



You blokes need to get out more often.:O:O

When viewed full-screen, you can see lots of little wobbles in the pitch and yaw plane - a machine of real size and weight (with the subsequent inertia in pitch and roll) could not wobble that fast without some serious stresses.

Check video at 1:24 for weight indication
 

Mick,

If you know or have access to the actual flight vehicle dimensions, just provide them. It may be capable of fitting two passengers, but it appears smaller than he non flying mockup shown earlier in the video.

Regarding the flying aircrafts actual weight. Stop the video at 1:24 and look at the landing gear being used. The three thin curved hoops of either composite or metal could not support a realistic weight of a two passenger aircraft.

OK, I relooked at the video and a number of questions came to my mind.

1. why did it take off from a taxiway and not from either the runway or a helicopter landing pad?

2. for a first flight why was there no flight data probes? surely you would want to know the environment that the aircraft was flying in?

3. Why did they not list the airport that they took off from, every other first flight video tells you the time and date and where the first flight occurred? Was this flight legal?

4. When it took off it had aGoProo mounted at each wing tip let later on in the video there was one missing, did it loose a GoPro if not was it the second flight that we saw later on in the video?

To be honest there are too many questions and not enough data to make those questions disappear.

Re the previous posts, sensible questions from Ppruners, which have been put to the company on social media.
They have replied directly, saying the video was edited from more than one flight during their test program and the craft was their full size two seater.

This conversation raises the question of the definition of a "prototype".

Weight and dimensions please
 

Mick,

Weight and dimensions please. Then the truth is clear.

You mean an 11,000 lbs with 1,100 SHP engines helicopter compared to a 23,000 lbs gross weight aircraft and rated jet engine?
Yeah, the noise may be different.

ESA are involved. I doubt they'd put up with fake videos.
ESA website

The ESA web site so helpfully referenced says the concept has been 'validated ...with several scaled prototypes weighing 25 kg'.
It goes on to say that Lilium is now developing its first product, a two seater ultra light...
I think that settles the matter, the video is of one of the prototypes.

A Manager at Lilium HQ have said it was their full scale 2 seater used on the maiden flight video and that the video contains pictures from multiple flights.

You could estimate the craft dimensions from the drone shot with the tech laying underneath.

I'll ask about weight but don't hold your breath:)
One assumes their plan for world domination has factored in the prospect of evolving battery efficiencies.

Pity they didn't show an unedited flight from takeoff to landing. I've suggested they release an unedited shot from the camera drone that was also airborne.

That's what also caught my eye. It's unfortunate that this start-up felt compelled to release video of a vehicle that clearly does not conform to a production configuration, making a very brief flight that demonstrated some potential stability/control issues.

Thanks Mick
 

Thanks Mick,

I agree. I won't hold my breath waiting for an aircraft weight.

Did they claim that it was a production model? I don't think so.

Similarly, the flying bedstead wasn't a production model Harrier.

PDR,
It was, apparently real person with a real job title in marketing who responded to me by email.

So both head of marketing and the co-founder are saying the same thing, that the video was of their full size 2 seater.

The flight took place at the Grob Airfield im Mindelheim.
