Introduction to Aerodynamics
Introduction to Aerodynamics Flying... still kind of magic every time. The math describing Fluid Dynamics was extensively studied and eventually written down in a complete set of Partial Differential Equations known as the Navier -Stokes . Those equations are so involved that mathematicians had been working on them for years trying to find out some assumption that could lead to a simplified sub-set, detailed enough to study basic aerodynamics in closed form. One of the most abused assumption was to discard the friction from the equation (potential flow only) . That looked to be a reasonable assumption (as friction in the air is low compared to other factors), however it leads to the impossible result that no drag exists and thus nothing can fly! ( known as the D'Alambert paradox). It was only in early 1900 that two brothers figured it out, and it's been an evolution ever since. It is all a matter o...
