Resumen:
The development of an optical contact instrument for measuring the
geometric shape of aerodynamic profiles on blades of small power wind
turbines is presented. The instrument uses the triangulation principle,
where a structured line laser pattern is projected onto the surface of
one of the faces of the blade under test, a camera captures the image of
the line and is processed to interpret the distorted form of the
projected line. A linear sweep of the instrument makes it possible to
measure the profile in another section of the blade. Comparison and
evaluation results of two symmetric profiles of the NACA 0012 family are
presented, one manufactured in a 3D printer and the other one is a metal
profile AF104 of a subsonic wind tunnel. Additionally, three sections of
a blade with profile FX 63-137 of a 1.5 kW wind turbine were evaluated.
An aerodynamic analysis shows a reduction in the lift coefficient and in
the efficiency of the aerodynamic profile, as well as an increase in the
drag coefficient. The sensitivity of the instrument is 0.1 mm on the
Z-axis.
