ABSTRACT: A fluid flow model consisting of Bernoulli’s law in its normal
form, the equation of state of air, and the cross-stream force balance between
a downward pressure gradient and the upward centrifugal force on fluid
particles moving along curved streamlines over the top circular wing surface
involving three equations in three unknowns (pressure, density and velocity)
are solved to show that both density and pressure decrease upward as the inverse
square of the distance from the circle’s center, and the velocity is
independent of that dis-tance. These derived characteristics are used to
explain the lift force on the wing in what is believed to be a novel way.
