This is the "penalty" for creating lift. It occurs because the pressure difference at the wingtips causes air to curl into wingtip vortices , which consumes energy.
Without viscosity, there would be no boundary layer, no starting vortex, no circulation—and no lift. The clean, frictionless world of textbooks is a mathematical ghost. understanding aerodynamics arguing from the real physics pdf
To understand lift accurately, we must look at how a wing interacts with the air as a continuous fluid. Real lift is generated through a combination of several fundamental laws of physics. 1. Newton’s Third Law of Motion Lift is fundamentally a reaction force. This is the "penalty" for creating lift
In recent years, a growing number of researchers and enthusiasts have been arguing that the traditional understanding of aerodynamics is flawed and that a new approach, based on "real physics," is needed. This argument is often supported by the claim that the conventional wisdom on aerodynamics is based on oversimplifications and incorrect assumptions, and that a more nuanced understanding of the subject is required. The clean, frictionless world of textbooks is a
Aerodynamics is the study of the interaction between air and solid objects in motion. It is a crucial field of study for understanding the physics of flight, which has numerous applications in aviation, aerospace engineering, and wind energy. In this article, we'll explore the fundamental principles of aerodynamics, discussing the key concepts, theories, and equations that govern the behavior of air and objects in motion.
The "real physics" perspective integrates these views. The wing acts as a pump, imparting momentum to the air. As the air flows past the wing, it is deflected downward (downwash). This change in the air's momentum vector requires a force, and the reaction to that force is lift. McLean argues that the pressure field is the bridge between the wing and the momentum change. The pressure difference on the wing's surface is the manifestation of the wing pushing the air down.
