AIRFOIL TERMINOLOGY

                       Air foil Terminology What is an airfoil? How an air foil is described in modern science, what are the parameters that determines its shape? An Air foil is primary building block of an aircraft which has two edges namely leading edge and trailing edge, the straight line connecting the leading and trailing edge of the air foil is called as chord line. The line which is drawn equidistant from the upper and lower surfaces of the air foil and connecting the leading and trailing edge is called as mean camber line.The distance between the leading and trailing edge is called chord of an air foil.   The maximum distance between the mean camber line and chord line is referred as maximum camber. This is one of the variables that determine the aerodynamic characteristics of the wings. Maximum thickness to chord ratio is expressed in terms of percentage. For subsonic wings the ratio is normally 12-14%   Depending on the camber (curvature) of the air foil it is d

Wing Components

                   Wing  components Wing is the main source of lift and stability of an aircraft in flight. Our doubt is how this structure controls the motion of the aircraft? These are the scientific facts behind that; first of all an aircraft wing resembles an air foil which creates lift when it is in moving air. Normally the wing is constructed with many components and they have their own characteristics. They are Spars Ribs Stringers or Longerons Skin Spars are the main structural members that bear the loads acting on the wing; they are extended from fuselage and are in right angles to the fuselage. Ribs provide shape and rigidity to wing, which resemble the shape of an air foil. They are arranges in chord wise manner from wing root to wing tip. Stringers or longerons are thin long materials usually fastened with the skin of the wing. The primary function of the stringers is to transfer the aerodynamic bending loads to the ribs and spars. Ski
