Please never stop putting the custom RCtestFlight music in these videos, I love it so much
all the effort and amazing footage of these experiments - and you comment on the music ?????!!!!
@@thesnitch7 the music is lit af!!!
@@thesnitch7 All the effort of mixing ingredients to bake a cake and you comment on the frosting?! C'mon bruh! The videos are great and the music is like a beautiful capstone.
@@CausticLemons7 who said the music sucks? Not me. I love the whole thing.........bruh.
BTW - thx for proving my point re:effort vs frosting - I agree 100%........bruh.
@@Pman353 yep. But it's not the main thing.
The smoke looks so cool when going into the vacuum
You are going to enjoy the Fan Showdown on the Major Hardware YT channel
How did he generate the smoke?
@@SandeepKumar-jj7zi some kind of smoke machine. It’s probably tiny water droplets.
WHERE STL
I love how 2:40 is just casually applied science as in
"hey this should work like that"
*tests it*
"oh yeah it does".
Every day I'm thankful for modern knowledge and the modern tools that let us so casually test stuff.
oh man i was expecting Ben from Applied Science to randomly show up
Except he's wrong. Exactly backwards. It's using less current because the resistance in increasing. It's harder for the rotor to spin because there's lower pressure on the inside but full pressure at the outside trying to rush in backwards. If he put his hand on the blades it would have the same effect - current would go down. For a fixed voltage current will decrease as resistance increases.
@@reginaldjeeves9825 An electric motor is not an resistive load. It contains coils of wire, solid pieces of metal, which current will just flow through creating a magnetic field. The fewer work that field does the more current can flow. The impeller not being slowed down by incomming air means it does less work.
Compressor engineer here, the current decrease has all to do with "suction throttling". What's happening is the restriction of air flow restricts mass flow. And the total reduction of mass flow is greater than the increased compression work (specific work done on the air). With suction throttling the Inlet velocity at the eye of the impeller is reduced but the exit velocity is not (it is relational to rotational speed) so for every gram of air the compression work is going up just not as much as mass flow goes down.
@@reginaldjeeves9825 except you're wrong since an electric motor is not a resistive load, but instead its an inductive load
Looking at the turbine with its housing, my first thought was: "oh no, he made an air raid siren". Look at the air raid siren from Matthias Wandel. Those equally spaced stator columns with the rotor blades are probably what makes that horrible noise.
"Horrible" depends on what type of person you are.
Yeah, you need unequal number of blades vs outlets, otherwise you end up with a siren :D
@@akkudakkupl Yep
Though there are some sirens that have 4 outlets but 10 blades or 10 ports, For instance, The CLM Siren. Another example would be the Thunderbolt series. With only 1 thin opening at the front
@@ctdcgaming2440 Well the more correct answer would probably be to have blades and outputs non divisible by a common denominator? For example two primes, or a prime and the same number -1 or +1.
@@akkudakkupl That's only to get a constant tone, I was mostly talking about the matching blade and outlet cutoff shape that significantly increases the noise because of pulsing.
9:35 - Congratulations on selling 23 690 420 kits, that is a lot of orders! Getting over 2 billion visits per second is also incredibly impressive :)
That's just impossible O_O
The revenue seems to be over 10B at 10:04
Nice
the Conv. Rate was also lit!
its fudged data XD
I recently picked up a Dyson V8 vacuum for cheap with no battery just to take it apart, the digital motor inside is just insane, in max power mode it pulls around 550w of power and puts out an insane amount of air, in low power mode its around 150w. I have converted it into a dust blower for dusting out PC's and its the best one I have ever used.
Makes sense why you only get 10 to 15 min on max... still impressive as hell though. Now if I could only get my kids to put it back on the damn charger....
Have you got any plans/pictures of the converted Dyson?
@@wakefieldallan Yes, but compared to a regular 1800w vacuum, they are impressive AF
Even the dyson V8 is nothing compared to the newer V11s and V15 dysons
I made a shop vacuum a week ago using the turbo style impeller and a cyclone. It actually worked quite well despite the poor balancing of the impeller causing a painful screech propably just wearing down the bearings. I actually got the idea from your cyclone video and hoped you would make a vacuum generator for it. Man I love timings.
Thats pretty cool!
Cool! I've been wanting to do something similar for the shop at my work, homemade giant vacuum and hide it behind a wall with a hose coming out. Those big central vac motors are not cheap but I think if I found an old motor I could make something work. Maybe skin the 3d print with glass or carbon fiber.
@@deathcogunit106 Some years ago we just used small forge blowers in our woodworking factory for dust and shaving extraction. The missus sewed up a bunch of calico bags to collect the swarf; used to work real well !
Empty it into the compost heap(if not treated pine!)
Loving these recent 3d print test type videos!
But we need STLs
The final destruction slow-mo and the music was absolutely perfect
Should have also tried a squirrel cage design. Poor static pressure, but they're hard to beat for flow rate.
Would be interested in a lobe and a screw type too.
9:07 I really like how the top part tried to put itself back after spitting out the plastic out the side!
I love the effort you will put in to reduce noises
I've never been interested in RC type videos. But your channel is so fun! I just love them all. Thanks man for all the interesting videos you share!!! I would be remiss if I didn't mention too that I love the jingles in your videos. It really makes them unique!
Yea the smoke looks cool. Thanks
The balance between planning and flying is the hardest thing for sailors. We now use speed to stay on the foils. It is all about the movement of fluids.
wow daniel has come a long way from foam planes to being one of richest man on earth, such humble beginnings, all it took was a snow cat project. truly a visionary.
Just for fun, you could combine the fan and the separator: In the radial blower on the outside edge of the scroll, add some holes or slots/vanes that leads to another scroll. Heavy particles will flow on the outside of the stream dragging the wall (like in the cyclone), as a hole appears it will get flung out. Now this other area in the secondary scroll is kept at a slightly higher pressure than the main exhaust via a damper, otherwise pretty much all the air goes there. This flow is routed to an inertial separator, but the flow is lower and more concentrated so it could be more efficient and smaller. (Or just a big vacuum cleaner bag)
If the impeller is subject to dust straight vanes are the best, but otherwise it would be fun to test the difference between backward and forward curved impeller vanes as they are more efficient.
3:10 CDC and WHO, would not approve of this design LOL
The music always hits me in the face because I never expect it to come. Also, those Dyson, although they cost an arm and a sausage, they are pretty well engineered, always fun to see the inside of them
Great choice of music for that slow-mo, You synced it up perfectly!
The German-Canadian wood wizard Matthias Wandel has some good impeller videos.
These impellers have names when used in hydroelectricity. The automotive turbo radial to axial or visa versa is a *Francis* turbine. The waterwheel type is a *Pelton* turbine and the complex with the six stages is a *Kaplan* sort (with hydroelectricity it is a single one). The Pelton is used when volume is low but the pressure is high (high up in the mountains). The Francis is used when volumes and pressures vary over a significant range. The Kaplan is used when there are huge amounts of flowing water but very weak pressures (Run-of-the-river hydroelectricity). Its all about stuffing limit and compressor stall and the depending efficiency in the compressor map.
Hey, Im printing impellers for my studies and testing them. Good work there guys, nice to see someone's approach!
I've been casually watching your videos for years, and i must say you have really upped your game. Keep up the good work
Honestly, there hasn't been a single video lately that hasn't grabbed me. Awesome channel, Daniel!
Excellent test! Destruction at slo speed is so oddly satisfying! Cheers!
The turbine section of some turboshaft engines use a low pressure axial flow fan to provide a high volume of low pressure air to a centrifical turbine as the high compression side of turbojet. Reduced number of stages with fewer parts, lighter weight and compact length. The output side is usually a free turbine providing power to the shaft with reduction gearing. They have impressive power to weight ratios.
Please combine design one and two, I'd be really curious as to if it would improve performance!!
I just downloaded the free version of Fusion 360 a month ago. Videos like this are giving me the gumption to get more into it. At the turn of the century, I was modeling parts like this for Honeywell - Sky Harbor in Phoenix, formerly AlliedSignal/Garrett AirResearch technical illustrations. I used AutoCAD Mechanical Desktop 2000 to model axial and centrifugal compressor and turbine bllades. Although I was creating 2D technical illustrations, I was given a box of paper drawings that I used to create accurate 3D models. One of my crowning achievements was creating an accurate 3D assembly for the Honeywell/Rolls Royce LHTEC T800 engine, which had two centrifugal compressors and conventional axial turbine section. I imagine that aircraft maintainers are using my illustrations to maintain an APU used on the B2 Stealth Bomber.
I very much enjoyed the demonstration of spontaneous catastrophic auto disassembly. Thank you.
Congrats on all the pre-orders. You're off to a great New Year.
I would love to see you do a few fusion tutorials. You are really good at explaining things.
This track is amazing, can't wait for the album to drop😄👌🏼
I wonder if you could print a plastic version of a Roots type supercharger just for your particular brand of experimentation...which is frickin entertaining and brilliant.
Such a fun project! If i had a 3d printer i would add dust shrouds to my router, pantorouter and other wood tools! Also would see if a closed system (by routing the blower vents to the front of the tool site so that air flow is not just vacuum but also blowing - not absolutely closed but as close as possible)
Those Dyson vacuums are awesome! I was so skeptical when my wife bought one but I'm sold.
3D printed everything babyyy!
On the turbo compressor, making the inducer to exducer ratio larger ie smaller inducer versus larger exducer will generally improve delta pressure across the housing. Increasingly positive blade rake helps, more positive curvature in discharge blades increases delt as does increasing the radius of transition of inducer exducer.
Adding a venturi nozzle about 3 diameters above top of inducer helps backflow.
Interesting but expected results
Brilliant work, Daniel! Congrats on your snowcat sales, too!
Right! 10 trillion dollars is no joke!!
@@getoffthegames89 Neither is a 420 percent conversion ratio
Need more space between the rotor and stator vanes if you want the fan to be quiet. 3-5mm worked well in my experiments. Since the rotor is 3D printed, you can use a fully enclosed rotor instead of leaving the vanes open on top. Also, in my experiments tip speed correlated the most with pressure and noise. So you can half-ass the rotor, but still get great noisy performance if you spin it fast.
We use those big “snail” blowers, as you call them, to move loose wool fibres around the factory. They work pretty well with straight blades on a conical body, to deflect the flow away from the centre. If you made the blades twice as wide, you would start to see some serious flow, with pretty good efficiency
The reason we use them is because they’re beefy as hell, and they don’t get worn away by the wool too much (wool is amazingly abrasive).
There’s no way to beat a multimillion dollar design like a commercially produced vacuum impeller, but it sure is fun as hell to try!
Awesome stuff man! Well done!
Loved the custom music 👌
Just wanted to say, watching the turbo explode was amazing. Please include in the future
Simple flow tester that can be used to compare things: DC motor fan. It will spin up as the flow increases and you can measure the motor output.
omg this is amazing, impellers are awesome
Your videos are so awesome man, keep it up!
A thousand million thank you very much, all the love to you from Jordan
I really like the new 3d printing videos.
Interesting: When you spin a motor faster by normal means, it takes more current, but when you let it spin up by reducing its drag, without also increasing the voltage or pulse width, then it takes less current! I hadn't thought of that!
The miracle of motor back EMF
I'd love to watch the Fusion360 design process! Great video!
I love how you just made a video about testing something not about flying but very related.
Love the convertion rate on your webstore! ♥
That song is so awesome! I testing my 3d printed water jet soon I wonder if it get disintegrated ! Great video as always 👍
Mind blown on the vacuum cleaner thing
Cool stuff. Most turbomachines (non-positive displacement) reach peak pressure delta across them around their mid volume flow capacity. You could be quite far down the pressure capability in your static suction test. My bet is the turbocharger style would win out for suction per watt input. Your axial flow design has the most potential but you need pressure taps between each stage to ensure each one is doing its part. Did each stage have a different blade design?
The song at 7:55 is too good. Upvoted!
The slow mo of the plastic induction caused pandemonium was great. Think about what it takes to make the compressor section of a large aircraft turbine able to sustain bird strikes, even through the hot section.
that slowmotion though man that was epic
Loved the browser inspector work on that huge revenue amount. 10 billion in revenue! NICE!
Please ask him to use his skills counter rotating on the US debt spiral clock $194500 per worker it is shows according to the vacuous wind bag OIG (Orifice of Inspector General)
The effect where a vacuum spins faster when you cover intake also works in reverse, even more counter-intuitively - if you force more air into the intake, like with another impeller, the second one will _slow down_ and draw more current from the added mass of air it has to push through itself.
That's how centrifugal impellers act. When you stop the flow, the air stuck in the casing is already up to speed, rotating with the impeller blades.
I can tell your prints are yours, by how you mix colors when you run out of one.
Colorful prints and videos all the way baby.
Love your water test !
This guy needs more subs he makes great content
I’ve been waiting for this video
Wow! Now THAT is AWESOME!!! Makes me wanna make somthing like that
Just came across your video, love the videos and the song you're an engineer marvel
Your channel is so interesting and satisfying to watch
I used a 29€ handheld but battery-free vacuum with a 450W asynchronous motor and a power regulator socket that's sold as a speed conrtoller for pond pumps (15€). Now can regulate the power between 100 and 450W and have a sufficient vacuum for my 3018 at 100W. I also printed a cyclone for a bucket and if anything goes through I still have the cyclone and the hepa filter in the vacuum as a back up. It's not as quiet as a dyson but it is surprisingly strong (the bucket needs reinforcement to not buckle inwards above 350W)
your printing skills are quite good
Your songs are the best part.
Ohh I simply love your videos!
Regards from Copenhagen Denmark
the cyclone track is 🔥🔥🔥 hahaha
Your axial linear design is the exact design a turbomolecular pump for ultra high vacuum uses.
The difference in working principle is that yours pumps the air in a classical manner while a turbo pump transfers momentum from the spinning blades to remaining gas molecules which when bounce of the static blades to get to the bottom. Thus the blades have to move at the same velocity as the molecules. Defending on the gas you want to pump this means rotational speeds of between 20,000 and 90,000 rpm!
I was waiting for an update on this thanks
Just ordered my first 3D printer and this video inspires the shit out of me!
I love the slow mo of the fan grenading itself 🤣🤙
That song was amazing.
would love to see more work/stages be put into an axial compressor ideally should perform at certain speeds with different blade pitches, would be really cool to give a optimal 3D printed Axial fan to Integza in a collab!
I did play that again hahah; I wanted to see that huge 3d printed funnel again.
Really funny cut-away.
Your test at 3 minutes in this video is very interesting and like water pump amperage in similar situations. But, it has been a long time since I had to think of that. You get my like and subscription for this video and I hope future videos like it.
so glad you played the cyclone song again!! made me laugh hard
that static pressure fan test would be a hell of a way to test FPV motors and props.
needs some sort of closed loop with a load cell.
May I suggest using two or more modified EDFs turning in opposite directions? It's effectively like putting a set of stator blades in without the complicated construction.
The axial construction could be simplified by either using a spline shaft and having the rotors and stators stack up or by having the stator ring made in halves instead of... well, rings.
Also tip clearances rob you some significant delta p.
Love this tinker project. The take apart the new Dyson, and try to replicate/improve it.
This is awesome and a smart idea
For the turbo design, definitely need anti-surge ports. May as well add a BOV while you're at it.
This along with your boating skills ....
Jetboat 🤘
Autonomous of course 👍

I think DIY Perks did a video on some kind of acetone mist bath (I think) that would help smooth out 3D print lines. It was interesting maybe a wonky way of making a "smooth" finished extruder print.

this is overkill vacuum! i love it!
I see you Major Hardware gang. 👀
Excellent and adorable work : Really Thank you
Continue, i love your videos
Smoothing the blades could be done with some polymer for resign printer. Apply some with brush and cure it with UV. It does pretty good job
The song is pretty amazing indeed
the Cyclone cover earned my sub
This is wonderful!!
