Re: pteros have lift-off
I think that's all l I had to hear. That's fixes everything if in
your model the wing stays folded until apogee or the beginning of the
downstroke. Sort of like a swan dive, except no swan and no dive.
It's still completely folded until about 0.25, more than likely.
But, if it wants, our leaping pterosaur can simply leave the wing
finger folded up until the 0.7 mark when it begins to downstroke.
It makes the initial upstroke faster anyway.
That makes a spectacular image.
Last question, how long of a run (in terms of # of footprints) -- to
gain speed to load the forelimbs -- before the leap? Perhaps zero for
tiny pterosaurs, more for larger ones?
PS The old image from Walking With Dinosaurs of old and giant
Ornithocheirus shuffling around like an old man on crutches has to go
by the wayside. No wonder the CG artists did not show it taking off.
Rather, like Bela Lugosi, they show you the 'before leaving the
casket' and the 'standing by the casket,' but not the 'awkward,
grunting, getting out of the casket.'
