Analysis of information sources in references of the Wikipedia article "Camber (aerodynamics)" in English language version.
Experiments that he began to carry out in 1804 allowed him to learn more about aerodynamics and wing structures using a whirling arm device. Cayley observed that birds soared long distances by simply twisting their arched wing surfaces and deduced that fixed-wing machines would fly if the wings were cambered. This was the first scientific testing of airfoils as the part of the aircraft that is designed to produce lift.
