Bruce Hoult a écrit :

Also, are you sure that drag is proportional to lift?

Induced drag is proportionnal to square of lift, while form drag don't
vary much with lift. Total drag definitely increases with lift, but to
quantify it that's where we need the proportion of induced drag...


And this is clearly totally mistaken, or misspoken.

.... or misunderstood ;-)

Two gliders flying
have twice as much lift as one glider, but they have four times as much
induced drag as one glider? And ten gliders have one hundred times as
much induced ddrag as one?

in this thread it is question of drag vs load factor - i.e. lift of one
glider, not of ten !
