Bernoulli’s principle


Cutting through to the essence

Wilbur and Orville Wright demonstrated heavier-than-air, controlled flight in 1903. Before this, in 1901, they built a wind tunnel to improve the shape of their wings. Possibly the first person to realize that Bernoulli’s principle explains the lift of an airplane wing was Edward Chalmers Huffaker, in a letter to Samuel Pierpont Langley in 1893. In 1895, Wilbur and Orville Wright obtained a copies of publications related to flight, including a paper by Huffaker, from the Smithsonian Institution. In 1911, Gustave Eiffel proved that Bernoulli’s principle was responsible for the lift produced by an airfoil.
