    Axial Centrifugal
AI Thread Summary
For a toy project aiming to lift an action figure six feet, an axial fan is recommended over a centrifugal fan due to size constraints and effectiveness. The choice of fan may be less critical than exploring alternative launch methods, such as rubber bands or springs. However, the focus remains on using a fan, with considerations for airflow enhancements like air straighteners to boost performance. Determining the lifting capacity of the fan involves understanding its specifications and weight limits. Overall, the discussion emphasizes the importance of fan selection and airflow optimization for achieving the desired lift.

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
 
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
