LEGO Wind Tunnel Smoke Testing (Airfoil-Wing, Cross Section)

So I’m not a fluid dynamics expert nor an engineer so we really don’t know what to take from this video but still, this looks a pretty cool. This video is actually pretty old almost 4 years old and we didn’t know much back then but it’s here. I made 2 designs and never really came through with making a full airplane mainly because it would be heavy. In the future tho maybe I could test how much lift it can produce compared to its weight.

😂 this is what happens when two dudes I left alone with a vacuum, Legos, and a vape

[@doctorTF_2]

lol i was thinking about they were using a vape aswell lol

mad brick?
is that you?

[@thisisaduck]

I see someone has had the same idea as me but better facilities. Wish I could see my aerofoil design in a wind tunnel.

[@angluneenon]

Desk fan and baby powder in your kitchen should work well enough.

ISNOT1 thanks

dont make a mess

Mad Brick I’ll just make sure to do it in a large cardboard box.

i was like: hol up, who is this dude? why did i get a notification of his video? and they i saw it. mad brick, is this you?

Apparently someone one reached out to him to change his username because mad brick was already taken by some company 🙄

How's it handle in hyper-sonic conditions?

[@madbrick923]

id probably just tape it to a f16

Mad Brick hahah maybe mig-31

[@SilverScarletSpider]

I’ve done some experiments with some of Lego’s helicopter propeller parts and designs. They spin and create lift surprisingly well. Put a fan motor underneath one of them once and it took off naturally. Always wondered what someone with more skill could do if a motor was integrated into the LEGO parts

[@madbrick923]

the brick experiment channel built a drone. wish i was that smart

[@Phil451]

It's definitely producing lift. If you look at the vapor coming off the back of the wing at higher speeds you can see a decent low pressure zone above the airfoil. Great job!

[@christiaanscholte329]

cant you put something on the end of the smoke blower thing that makes the hole really small so its not a cloud but more a stripe of smoke

[@cobaltdds9564]

Cool!

Nice

Long Live Mad Brick

[@fredbarnes196]

you need to angle the wing up a little to help the flow go over the top.

Why did you change your name? Love your content!

How did you made the wind tunnel? Searching how to make one cheaply

Lol it’s mad brick

You may think he's using the fog generator for the smoke but no
He's ripping fat clouds and blowing it into a tube

Lol i made the smaller one but it works 😂

make a lego plane that flies

Hi

[@juliacoloncruz6959]

Lego can fly mmmmm...

[@luisorduna2964]

I'm not a fluid dynamics expert either. But the bottom is too flat. Try rounding out the bottom and see what that does?

[@Phil451]

The bottom is fine. It's working.

[@chrundlethegreat1960]

All jokes aside. Did you guys get high and vape some Legos with a hair dryer.

[@madbrick923]

yea bro i vape

[@clementpoon120]

Mad Brick was much cooler.

[@madbrick923]

yea for sure
