PROLOG   Have you ever wonder what would an aircraft will be if the wings were absent?... why would a wing so important that various models of wings had been created through times...? or why would an aircraft engineer assemble's those aircraft with wings, which actually adding weight through out the aircraft..? we'll those question were running through my head every times, so I decide to search for answers. and here's it the answers.       " The design and analysis of the wings of aircraft is one of the principal applications of the science of  aerodynamics , which is a branch of  fluid mechanics . The properties of the airflow around any moving object can - in principle - be found by solving the  Navier-Stokes equations  of  fluid dynamics . However, except for simple geometries these equations are notoriously difficult to solve.   Fortunately, simpler explanations can be described." (source: wikipedia).   "Good ...
