Figure 14: Pressure across the three polylines, shown in Figure 4(d), when the blade deflection is (a) at a maximum, (b) at a mean, and (c) at a minimum, for the case of 0.5 mm gap. (d), (e), and (f) are the first spatial harmonic of the pressure across the same polylines for the respective blade displacements. Note the angle given is relative to the centre of the aerofoil.
