That makes no sense, according to that theory the wheel should
lower the amount of lift, seeing as the lower part of the wheel
is going in the direction of the air.
nope, he's right,
It's the greater speed of the upper part of the wheel that would
increase it but it's insignificant in any case.
Bertie
the amount of theoretical lift generated is negligible, whereas the
drag generated from extended gear is not
Well, exactly. though on some aircraft the drag caused during
retraction is considered worse than leaving it down in the event of
an engine failure!
Bertie
true.
Can't think of one off the top of my head, though!

Any A/C that the gear rotates 90 degrees to stow would have greater drag
during the "Rotate/Stow" sequence.

Well, I ws thinking more of ther gear doors opeing and closing during the
sequence.
Bertie
which in Tarverworld would mean that the transitioning gear doors,
creating drag, would therefore be acting like a spolier and seeing
that a spolier is a flap will make the wing thicker therfore creating
lift.
ergo a gear door is a lift device !
