Beschreibung
Zusammenfassung:	The invention relates to a method for producing or designing a leading edge of a lifting structure, wherein starting at the midpoint of the base (0,0), a curve is applied to the profile of the structure, the length "L1" of which is according to the maximum thickness of the NACA section in the base of the profile "H0" in the base and is defined by the equation L1=0.0510H02−0.0790H0+15.5790, and the maximum height of which on the "x"-axis is located at point "L1/2" and defined by means of the relationship x=0.0137(L1)1.4944, the shape of said curve being defined by means of the equation: (y−y0)=0.0000000107x6+0.0000016382x5−0.0000794412x4+0.0010194142x3+0.0097205322x2+0.0136993913x, and the rest of the curve being calculated by means of an iterative process according to the above.
