Dataset for lift and trailing-edge deflection of passively morphing aerofoils

This dataset provides the results of the time-resolved force and trailing-edge deflection measurements for NACA0012 aerofoils undergoing periodic plunging motions. These experiments are conducted at the water channel facility at the University of Edinburgh. The aerofoil has a chord of c = 0.15 m and a span of 0.3 m. The flexible part of the aerofoil is made of glass-fibre composite, which has Young’s (tensile) modulus E = 1.86 GPa and density ρm = 2600 kg m^−3. The length of the flexible skin-section is 2/3 that of the chord. The trailing-edge surfaces have thickness b = 0.6 mm, giving a second moment of area of I = 5.4 × 10^−12 m^4. The reduced frequency is fixed at k = 0.2.
