The 'Great Debate' - Spitfire vs BF109

[taildraggernut]

Yes it is because it does NOT accurately describe what happens in the real world.

But is 'does'

As a general rule though, it is the buffet.

It is not good design to put the tail in the wings wake.

the buffet as a result of the turbulence impinging on the tailplane yes, we are talking about conventional aircraft here, you know the ones with the tail at the back like almost every aircraft flying even today has it, where the empennage is very much in the wake of the wings.

I certainly did explain it. What part did you not understand? Exam these graphs and maybe you will understand.

I see a Cd curve which continues on a smooth path and seems unaffected by anything, a Cl curve falling off at the stall and a standard L/D arc that also seems pretty unremarkeable but nothing showing how drag increases lift.

If we add drag, then our wing will change angle of attack to compensate because it requires more power. Our lift coefficient will increase.

the wing changes AoA all by itself? where does the 'more power' come from, these things don't happen unless demanded by the pilot and you certainly don't seem to be suggesting that.

The relationship of lift to drag is fixed by design.

yes it is, the L/D curve is the combined effect of Cd and Cl, in all your little graphs all I can see is the drag continually rising but lift dropping off at the stall, where exactly am I supposed to be looking if I want to see drag increasing lift.....am I being too litteral? I am only asking because you said verbatim 'drag increases lift'
