Streamlines, Lift, and DragĮven if it is not obvious from the above discussion, it should be intuitive that the shape of an airfoil will determine both the angle of attack (due to the chord length orientation shown above) and the forces acting on the aircraft. The shape (radius of curvature) and velocity of these streamlines will determine the amount of lift acting on the airfoil, while the velocity and shape of the airfoil’s surface will determine drag acting on the aircraft. The direction of oncoming wind (airflow) is marked above to illustrate the definition of an airfoil’s angle of attack as air flows over the airfoil, it should be clear that it will form streamlines across the top and bottom surfaces. The aircraft’s speed increases and rudders can be used to orient the aircraft’s angle of attack and velocity so that lift is achieved and the aircraft can climb to higher altitude.
