Around 1299 A.D., it was written that the great explorer,
Marco Polo, saw Chinese sailors attached to kites being used as military observers. This could be
considered the _____ - Answers first "manned aircraft."
Historians agree, however, that the first true powered flight with humans on board was in ________ and
the event occurred in France during the Eighteenth Century. - Answers a hot air balloon
on a wing, the upper side is more/less curved than the lower side - Answers more
bird wing tips trace a _____ as they move though the air. - Answers figure eight
Bernoullian lift - Answers there is a pressure difference between the upper and lower areas of a wing
(top of wing)
Newtonian lift/dynamic lift - Answers there is a pressure difference between the upper and lower areas
of a wing (bottom of wing)
how does a bird produce drag? - Answers A bird
uses it tail feathers and its wing feathers to
steer, brake, and produce drag, as well as
lower speed lift.
what did bernoulli discover - Answers relationship between pressure and flu- ids in motion became the
cornerstone of the theory of airfoil lift
Bernoulli found that the pressure of a fluid, like air, drops when it is ______. - Answers accelerated
common cap plane for oflights - Answers CAP Cessna 172 Skyhawk
camber on the topside of the wing causes the oncoming air to flow much___ over the upper surface -
Answers faster
the theory of equal transit time - Answers the molecules of oncoming air split at the front of wing, they
traveled over and under this airfoil and met at the back (trailing edge) of the wing at exactly the same
time THEORY IS WRONG - top goes faster
