Yes, maybe I misspoke, I know that drag is influenced by the design of the airfoil ect but let's pretend that we study an airfoil, I learnt that the drag formula was the same that the lift formula. So I don't understand why Induced drag change for a factor of 1/V² and why Cdi for a factor of 1/V⁴
Hi everyone. I was wondering if you guys could explain me why I saw people say that:
Induced drag changes for a factor of 1/V2
Induced drag coefficient for a factor of 1/V4
If I don't make any mistakes, Drag = 1/2 rho * S * V² * Cd.
Manipulating the formula I find, 1/Cd = 1/2 rho * S * V² *...
