Scaling of the Transient Hydroelastic Response and Failure Mechanisms of Self-Adaptive Composite Marine Propellers

Table 3

Circumferentially averaged values of the hydrodynamic load coefficients and blade deformations in wake fow for the full-scale, Mach-scale, and Froude-scale propellers (𝜌=1025 kg/m³, 𝜈=1.004×10⁻⁶ m²/s, 𝑔=9.8 m/s², 𝑎=1560 m/s).
