External shape of aerofoil section with profile thickness of 13 per cent, profile curvature of 4 per cent, and moment coefficient with value smaller than 0,004 can be clearly represented by curve with equivalent tabulated values

摘要

The external shape (2) of an aerofoil section (1) with a profile thickness of 13 per cent, a profile curvature of 4 per cent, and a moment coefficient with a value smaller than 0,004, can be clearly represented by a curve with equivalent tabulated values. The external form of a thin wing root section with a profile thickness of 14 per cent and an inverted profile curvature of 3 per cent can also be clearly represented by a curve with equivalent tabulated values.
