Embodiment
[0034] Please refer to the attached figure 1 -7, the technical problem to be solved in this embodiment is how to reduce resonance and reduce vortex-induced force, so a new type of marine rudder that reduces vortex-induced vibration is provided, and the new type of marine rudder that reduces vortex-induced vibration includes:
[0035] Flat side and zigzag side. The overall three-dimensional shape of the flat side rudder is shown in figure 1 ; For the main size parameters of the two-dimensional cross-section along the figure 2 ; See the overall three-dimensional shape of the zigzag side rudder image 3 ; See Figure 4 for the main parameters of the zigzag trailing edge.
[0036] For flat side rudders, the thickness t of the flat plate is smaller than the thickness T of the side of the small end of the rudder, and the smaller the better, but the strength requirements must be taken into account, and t is not less than 10mm; the length l of the flat plate and the side thickness ...
