do you know how many a "wings" have to spins per second so that a human can fly?

Question

propeler how many times plz and TY

I just need the info that can help me with my homework also the "wings" part is the nose of an airplane also it is not realistic
anyway if they had proper on their feet i mean

Answer 1

Havn't a clue what you're talking about but #1 want to say STAY IN SCHOOL, young people really need to do that these days.

As for my best guess, a small plane turns around 2500 RPMS, a larger plane up to 2700 RPMs and then if you get into really big propeller planes the RPMs drop to around 2200 or even as low as 1900 RPMs.

FYI, a propeller is a wing. A spinning wing is called a rotary wing aircraft AKA Helicopter. For a helicopter to make a human fly just requires more lift than weight. That is a function of the airfoil shape, length of blade, and speed of rotation combined with the angle of attack of the rotary wing. Once you know those variables then you can take a guess at how many wings need to spin per second so that a human can fly.

Answer 2

What? Far too little information. Humans don't have wings or the structure to power them, if they dod have they wouldn't spin, that's a mechanical thing, if they flapped then it would depend on the size, small wings would have to go like heck and big wings would go slower.

You still aren't going to get a decent answer. A small human would weigh as much as a very big bird. White Tailed Sea Eagles and Condors flap around once a second, faster when they are in a hurry, slower when they are in gliding... obviously.

Answer 3

I am a pilot, & have been flying for more than 20 years, & I can't make any sense of your question. Sorry!

Answer 4

it depends on weight of that person, on the shape of the wing(chord, area etc) and on many other factors to determine the answer of your question

Answer 5

you should concentrate on your English home work first before you think about flying

Answer 6

120? that's what some of the insect do
