According to Bernoulli’s principle, an increase in fluid speed lead to pressure being reduced or to the fluid’s potential energy being decreased. It is used to shed light on the mechanism of flight. As an aircraft’s wings are tapering, air passes considerably faster over the top compared to the lower surface.
The pressure difference results in an upward force being produced. When it exceeds the plane’s weight, the latter starts to lift up. Tammaro (2018) also stresses the importance of the attack angle and states that, together with the wing’s shape, it makes life possible.
