doesn't seem possible - new realms of aerodynamics
explored by the bee
Fig.1. The leading edge vortex (LEV) sheds from a translating model
insect wing, regardless of its sweep angle, whereas it remains stably
attached when the wing revolves. The LEV is visualized at Reynolds
number Re=110 and 1400 with small air bubbles
released at the leading and trailing edges of the wing. The distance (s)
traveled by the wings is given in chord lengths c
at the radius of gyration Rg.
(A) LEVs are unstable on swept wings, shown for 40° sweep at =36° and Re=1400. (B) The LEV
is also unstable on the same wing without sweep. (C) Revolving the same
wing results in a LEV that remains stably attached, shown for clarity
at Re=110 and s=8c, where s is
the distance traveled in chord lengths. (J

Some other fascinating characteristics of bee
is blunt natural selection capable of engineering this, when man still
can't get a million miles near!
There is none so blind as the man who will not see.
And there's so much more to bees!
