A new singing lesson

摘要

Singing propellers, though rare, are a well-documented phenomena and problem for the marine industry that can considerably impact comfort levels onboard vessels. In an effort to expand the industry's current understanding of the issue and how to avoid it, Wartsila and City University London have conducted a joint research project that has reviewed the industry's perception of the issue and pinpointed the specific design parameters that create risk of propeller 'singing'. This has ultimately revealed that the occurrence of the phenomenon is more complex than first thought, and spurred development of a new methodology that enables design stage assessment of the potential risk of singing propellers, allowing earlier identification of the problem.
