During the late 1920s and into the 1930s, the NACA developed a series of thoroughly tested airfoils and devised a numerical designation for each airfoil — a four digit number that represented the airfoil section''s critical geometric properties. By 1929, Langley had developed this
READ MOREThin airfoil theory is a straightforward hypothesis of airfoils that relates angle of attack to lift for an incompressible and inviscid flow past an airfoil. This theory idealizes the flow past an airfoil as two-dimensional stream around a thin airfoil which can be envisioned as tending to an airfoil of zero thickness and infinite wingspan.

The latter sections deal with simple results that relate the airfoil geometry to its basic aerodynamic characteristics.
READ MOREHumble beginnings: The first ever successful aerofoil was created by Otto Lilienthal in 1891, he was a German aviation pioneer who had graduated from the Berlin University with a mechanical engineering degree. Moreover, his breakthrough in the design of the aerofoil was aided by his fascination with birds and how they fly.
READ MORE2.2 Historical Overview of Aviation Propellers Aviation propellers have a rich history, starting with their initial use in the pioneering days of flight in the late 19th and early 20th centuries. They have evolved dramatically over the past century, from the simple wooden designs used by the Wright brothers, to the complex variable-pitch and contra-rotating

Despite that fact that he is today mainly remembered (if at all) for that one achievement, Clark was a many faceted and somewhat controversial aviation pioneer.
READ MOREHistory of Airfoil Development. The earliest serious work on the development of airfoil sections began in the late 1800''s. Although it was known that flat plates would produce lift when set at an angle of incidence, some suspected that shapes with curvature, that more closely resembled bird wings would produce more lift or do so
