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

Figure 3

First five wetted excitation frequencies, 𝜔_𝑖, normalized by the propeller rotational frequency, 𝑛, for the full-scale, Froude-scale, and Mach-scale propellers. The results correspond to the full-scale propeller operating at 𝑉_𝑎=20 knots.
