Please never stop putting the custom RCtestFlight music in these videos, I love it so much

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.

The smoke looks so cool when going into the vacuum

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.

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 :)

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.

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.

Loving these recent 3d print test type videos!

The final destruction slow-mo and the music was absolutely perfect

[DeltaOps]

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.

3:10 CDC and WHO, would not approve of this design LOL

[giga-chicken]

Should have also tried a squirrel cage design. Poor static pressure, but they're hard to beat for flow rate.

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.

9:07 I really like how the top part tried to put itself back after spitting out the plastic out the side!

Great choice of music for that slow-mo, You synced it up perfectly!

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.

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.

A few thoughts (based on my own experience):
1. In snail-type blower it is always better to add disk-shaped basement to rotor. it is sturdier that way.
2. thicker paddles also helps with durability
3. there is not much difference, if any, between turbocharger-style compressor and snail-type blower.
3. for the highest static pressure - a few centrifugal blowers in series. Many vacuum cleaners uses two staged blower.

The German-Canadian wood wizard Matthias Wandel has some good impeller videos.

Honestly, there hasn't been a single video lately that hasn't grabbed me. Awesome channel, Daniel!
