estimation of the torque of a drone

[goykmol]

hello,

for a project in my schools i just need an magnitude of the resistive torque created by the blades of a drone(with 4 blades)

if you have sources or an easy way to calculate this it would be perfect !!

 

thank you in advance

 

and i'm sorry if i'm not understandable, i'm french and not very good in english so don't esitate to ask me to reformulate

What information do you think you will need?

Let's start with the equation for torque.  r x F

 

What are the values for r and F?

hi

i know this^^, i look for a way to calculate the force of the air on the blade

What is the mass of the drone? Do you want to know the forces when hovering or accelerating as well?
