Leo S

Thanks a lot. However knowing these 3 things is it not possible to use an integral to find the force the blades produce at every point along its span? I figured this could be done fairly easily by using the sin of the angle divided by the hypotenuse or would I have to take into account rotational physics. Sorry if I misspelled anything, im on my phone

Hey my name is Leo Saturday, i am trying to figure out exactly how to determine the amount of force a fan will produce given a certain fan angle, fan rpm, and fan blade radius. I would like to know this because im trying to determine what is the easiest way to lift a human off the ground using simple fan power. Thanks alot for whoever helps me out.
