Air Powered Assited Module (APAM)

Off Topic ....

For those Micro RC fanatics out there I just created a 15mm Ducted Fan unit for micro RC planes

15mm Duct Fan 10 blade by scubabatdan on Shapeways

Was looking at the blades of different types of motors and always loved micro RC, so I created and ordered a set to see if my .24" dia 16,000 rpm 3vd motor will drive a micro plane using this.

Hey Dan,
I once played around with an old kitchen exhaust fan and bent the blades to different pitches until I achieved the optimum air flow.
So..... with this said, would it be worth it for you to construct tin blades and bend them until you find the best air flow and later design the blades to match the results?

Dan didn't you hear? Ducted fans went out a few years ago. lol

Blade looks good for a ducted.

LOL, yeah I have watched that video before. BTW that is a real gas powered micro turbine. I am just using electric motors and air power
Thanks!

Ah well, I have already ordered the fan and got the motor in today! YAY, will see how it goes. Trial and error
But a tin blade woul be easy to construct and then modify the CAD to match. Cool idea.

Yeah, but it should still produce a few grams of thrust.

We will see whan I hook it to a micro plane LOL

Dan you amaze me with what you come up with I was thinking ( Dangerous ) but would there be a way to actually make this a part of that stardust carto with out the use of the adapter , like have the fan in the bottom of the carto and part of it ? now that would be one bad azz carto I can just see it now, the scubatdan air propeller carto or Atty

Thanks, LOL the problem is the length of the motor and fan combined. The current 5/8" motor and fan combo will be about the length of a carto.

New Motor:

Current draw on this motor is about 110ma, variable RPM depending on voltage.

You are a genius, brother! Thank you for everything you have done for the vaping community!

Yeah, we need to start the Mod God Hall of Fame


BTW, potential inductees have to send me one of their creations in order to be considered

Nice job! I was just checking out OpenPilot and CC3D for helicopter auto-stabilization and making your own UAV. Perdy awesome stuff

This is small. And 3 volts http://www.microflight.com/Online-Catalog/Motors/Motor-4mm-X-8mm-11-Ohm

Dan, please let me know how the micro rc plane project goes, even though it isnt vape related, I'd like to know where you post about it. That pic before was from an article about 3D printing parts for a 'real' plane, though they cnc'd stuff too.

Yep that is the same one I am using currently from radio shack. It was a vibration motor the I removed the weight from.

Will do!

Pretty wild the things you come up with. I got two things to throw at you that came to mind. It might get your wheels turning in a different direction.
First I noticed you had this on a Provari. I got to thinking about the extension caps, having the fan in there and the center post on connector drilled out to allow airflow through the whole mod to atty/carto. Just thought it's give you a little more space to work and get the fan noise further from face.

Second thing, I don't really think you can use, but it might spark an idea. I used to mod computers about ten years ago and they came out with these shaftless fans. The windings and magnets are in the housing and blade ring. They are much more efficient because you don't have the big dead space in the center of blade. I don't know what's became of the technology, they might have micro versions of them now. I figured you'd find them interesting even if you can't use them for this. Here are a couple old pics I have of one:

This may have more air volume than fan type. Definitely more static pressure. looks like 1 l/min. I suppose that is litre.
MZB1001T02 Murata | Mouser
Frame Dimensions (mm): 20 mm x 20 mm x 1.85 mm
Static Pressure=1.42 kilopascals = 0.205953588 pounds per square inch

 

[Scubabatdan]

Thanks everyone for the ideas

I had a plan form this morning when I got notice that my 15mm x 15mm x 4mm fan shipped... Wanna see?

I know, well duh!

Rather than rip the fan out of it, I am onto proto #3, havent got proto #2 assembled yet

Ok, here is the fan I ordered:

That will go in what I made tonight:

I left 4mm of space on the inside between the bottom of the top cap and the botttom lower half.
More to follow... waiting on the fan to show up.

This is interesting - piezoelectric air pump. Thanks for the link perlionsmitnick

Agreed, I ordered one last night

Mock up, installed on my mag mod....
