Introduction:
Airfoil design and selection is an important deciding factor in aircraft performance. Airfoil is a term used to describe the cross section of the aircraft wings. By observing birds in flight, man has understood that flat plates, resembling bird’s wings can produce the necessary lift to set the aircraft flying. However the actual importance of airfoil in designing the wings of the aircraft was recognized only in 1800. Since then many engineers have designed, tested and patented a number of variations in airfoil pattern. Over the years, there has been a remarkable advancement in technology of airfoil construction and also in ...
