Which Fan Is Best for Vertical Lift in Toy Projects: Axial or Centrifugal?

[wangbungal]

Hello all!

I just want to ask help from you guys, I am trying to select which fan would apply on my toy project, ok, here is my setup, I have a base, and on it is a fan and on top of that is a tube, like a duct, and what I am trying to see is what kind of fan i can use to ascend or make a full action figure inside a clear duct to go as high let's say 6 feet in the air,heres my schematic diagram.

and other inputs would highly be appreciated!

I think that for this application, choice of fan is fairly irrelevant so far as performing the job goes.

What I would say is that getting a small scale centrifugal fan isn't going to happen. So it basically must be axial.

Why limit yourself to a fan and tube launcher? There are other ways you might launch your action figure to around six feet altitude. Rubber bands, springs, trebochet, and more.

I heard small scale centrifugal fan is kinda bulky, so axial it is,so an axial fan would do, i was looking on some grainger axial fans, but how would i determine the amount of weight my fan could push upward?

if i do that, wheres the fun with that? id like to use a fan on how much weight it can launch, i was thinking of putting a air staightener to further increase flow in the tube,thus creating more launching power
