### Re: Why does induced drag decrease as airspeed increases?

Hi, Ok so I dug out my notes and yes the vortices are causing the downwash. So basically the vortices DO NOT cause the induced drag directly because the wing is dragging them around like an anchor but they ARE causing the downwash which is causing the induced drag. Piloting types I have been around ...

### Re: Why does induced drag decrease as airspeed increases?

As I said I may be mistaken, did this almost 10 years ago now. Could also be how you look at it, what causes what, etc. and honestly speaking these are all mathematical models of reality where the downwash and vortex exist concurrently and are intrinsically linked. I have also had my fair share of e...

### Re: Why does induced drag decrease as airspeed increases?

I don't think that's 100% accurate. That sounds like induced drag is a direct result of the tilt of the wing: "some of the low pressure is now behind the wing, whereas some of the high pressure is in front of the wing. This "pushes" the wing back." That would also mean, if you t...

Combining the two equations: D_I = C_DI*(1/2*rho*v^2)*S D_I = (([C_L]^2)/(Pi*AR)]*(1+d))*(1/2*rho*v^2)*S D_I = {([C_L]^2)*(1+d)*(rho*V^2)*S}/(2*Pi*AR) But looking at the lift equation: L=C_L*1/2*rho*v^2*S C_L=2L/(rho*v^2*S) Substituting into the above copied: D_I = {([2L/(rho*v^2*S)]^2)*(1+d)*(rho*...
