The paper explains how lift arises for an airplane wing during horizontal flight at high speeds by describing five vertical forces acting on the airplane: gravity, pressure-gradient, Archimedes force, a potential force (known from Bernoulli but said not to have been accounted for in terms of its effect on the airfoil), and a vortex force derived from applying the action minimum to a continuous medium. It argues that, at high speed near the speed of sound, the vortex force points upward and compensates for gravity, offering an explanation of the vortex trail behind the airplane. The key limitation explicitly implied by the abstract is that the vortex-force contribution has not previously been considered in aerodynamics, suggesting the work is more explanatory/theoretical than experimentally validated. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract In this paper, an explanation is given of the lift force of an airplane during horizontal flight. It is shown that during a flight, five vertical forces act on the airplane: gravity; pressure gradient with a minus sign; Archimedes force; potential force and the vortex force obtained from the action minimum. The first three forces were known before. The potential force was also known from the Bernoulli equation, but its effect on the airfoil from the air had not previously been taken into account. The vortex force obtained from the minimum action in the application to a continuous medium was not taken into account in aerodynamics. In horizontal flight the vortex force is directed upwards, it compensates for the gravity of the airplane at high speed commensurate with the speed of sound. The paper provides an explanation of the vortex trail behind the airplane, mentioned in the Millennium problem Navier-Stokes equation.
