Jets have multiple types, EDFs are not included. It typically requires a sort of Venturi that increases velocity

I think "Jet" here is a misnomer. I jet is essentially a rocket that gets it's oxidizer from outside of the aircraft.

It's basically a drone that you could sit in, not a jet. It doesn't look very fast either from the video.

Got bored and did the math when this first went around. Batteries would be 1200-1500 pounds alone.

The "jet" in the video doesn't have a pilot in it. Right now, it's still just a big RC quadcopter.

Wouldn't it nose dive the second you lose power with the wings that far back? Especially with an american flying huehuehue

8 years ago | Likes 3 Dislikes 1

American models will have the wings at the front.

8 years ago | Likes 1 Dislikes 0

By design, yes it would. It has no control surfaces beyond the motors. Without power, no control at all.

8 years ago | Likes 2 Dislikes 0

Much like, say, a helicopter?

8 years ago | Likes 3 Dislikes 0

The falling of a helicopter makes its rotor keep spinning. It can only go down at that point, but the fall is controlled, part of training.

8 years ago | Likes 1 Dislikes 0

As long as the rotor is spinning you can control a helicopter without power. Just not a lot of say in where you're going to land

8 years ago | Likes 1 Dislikes 0

You have more say in where than when, though.

8 years ago | Likes 1 Dislikes 0

Helicopter has plenty of control after losing power. Landing is safely performed given they have enough altitude and airspeed to find a spot

It's the engine that defines it not the fuel type

8 years ago | Likes 28 Dislikes 7

If it was using an electric drive to mix particles of fuel with compressed air before igniting them, then it's a jet, otherwise its a fan

8 years ago | Likes 1 Dislikes 0

We can be pretty sure its not using a jet engine, you know, being electric and all

"Jet" includes more than turbines. Rockets and water jets are jets, too.

8 years ago | Likes 10 Dislikes 1

Yea but shrouded fans are not jets. Lilium is just using it as marketing buzz.

8 years ago | Likes 4 Dislikes 0

https://lilium.com/technology/ from what it says here, it's a jet engine, but the intake fan is powered by an electrical motor rather 1/2

then a gas turbine 2/2

8 years ago | Likes 3 Dislikes 3

Yea that's a fancy way of saying it's a shrouded prop with no turbine at all. If there's no combustion, it doesn't need to pull energy ...

That's not jet propulsion though, it's fans. Jets use combustion to accellerate air, turning fans. These are using electric motors to turn.

Jet just means it produces thrust by moving a fluid, it has nothing to do with the means to move the fluid

Jet engine: an engine that produces motion as a result of the rearward discharge of a jet of fluid; specifically :an airplane engine (1/2)

8 years ago | Likes 7 Dislikes 1

(2/2) that uses atmospheric oxygen to burn fuel and produces a rearward discharge of heated air and exhaust gases. - Merriam Webster

So, maybe it's a "jet" engine but not a "jet engine".

Ducted fan is the term you are looking for.

8 years ago | Likes 20 Dislikes 1

So long as it sucks, squeezes, bangs and blows right?

8 years ago | Likes 32 Dislikes 9

Kind of hard to pull off the "bang" part with all electric, unless you're looking to have it fall out of the sky on fire due to a short.

So does the engine in a lawnmower, but I wouldn't call that a jet.

Different combustion. Unless you've got Tim Allen's lawn mower because I think that one IS a jet...

8 years ago | Likes 2 Dislikes 0

Its all about thrust my friend

8 years ago | Likes 1 Dislikes 0

No bang, EDF or electric ducted fans. They suck, squeeze a little bit but that duct improves the fans performance more so than compression.

8 years ago | Likes 4 Dislikes 0

Jets of air come out of the ducted fans, is a jet.

I have a hose with sprayer that has a Jet function..... Jet water hose

8 years ago | Likes 4 Dislikes 0

Yes, it is when that setting is on. The compression of the water increases the pressure and causes thrust when released.

It has jet engines. Just electric versions instead of fuel. And it looks like it has several dozen small ones working in parallel.

The problem is this doesn't meet definition of a jet a jet involves exploding fuel these are highly Advanced propellers

8 years ago | Likes 13 Dislikes 0

Not necessarily. As I understand it, the engine compressing the air could propel it, but at much lower speeds the a commercial jet (1/2)

8 years ago | Likes 5 Dislikes 1

Which uses the burning of the fuel to increase speed. This info is from a 20 min google session so im not sure how accurate it is (2/2)

8 years ago | Likes 3 Dislikes 0

For jet engines to work they require combustion fuel. This is an example of a electric propeller with ducted fans. Very different.

8 years ago | Likes 1 Dislikes 1

Jet propulsion is a bit looser defined. Think of something like a 'jet ski' or how cephalopods move around under water.

8 years ago | Likes 3 Dislikes 1

True, but usually that means including rocket motors a la Jet Propulsion Laboratory. 'Jet' commonly refers to jet engines, not propellers

8 years ago | Likes 1 Dislikes 1

But it doesn't use propellers, it's compressed air that gives it thrust. The fans are for air intake
