Analysis of the Boundary Layer on a Highly Flexible Wing Based on Infrared Thermography MeasurementsMertens, C. (author), Grille Guerra, A. (author), van Oudheusden, B.W. (author), Fehrs, Michael (author), Ritter, Markus R. (author)The effects of the wing skin distortion on the boundary layer of a highly flexible wing are analyzed in a wind tunnel experiment using infrared thermography measurements. Considerable differences in the boundary layer flow are observed when comparing the sections of the wing near the ribs, where the design shape of the wing is preserved, and...book chapter 2024
