APROXIMATION OF THE IDEAL WING BY STREIGHT LINES
The ideal wing has a parabola shape. Its realization is made
practically by using straight lines, resulting V wind, U wing, and Uoptimal wing.
Uoptimal wing is close to the parabola shape. Its deviation from the parabola is
of maximum 0.08 h (height of the wing extremity) at 0.5 t (t-half wingspan, 0 is
at the central wing), and to V wing (the most resistant to the shocks) of only 0,3
h, in the same point. U wing, having the extremities starting from the half of the
half wings, presents a 0.25 t deviation from parabola ideal wing and to V wing
of 0.5t in the same point (0.5 t), being less resistant to shocks.
