WebAug 27, 2024 · Highly-skewed propeller (HSP) is widely used in submarine propulsion due to its excellent noise reduction performance. However, thinner blade and larger skew makes it vulnerable to respond to the hydrodynamic loading, which may even lead to structural damage. Therefore, it is advised to analyze the hydro-elastic performance of the HSP in … WebApr 15, 2024 · This paper describes the measurement of pressure distribution on a highly skewed propeller, HSP in short, of the same ship “Seiun-Maru”. First of all, the special pressure pick-up was improved taking account of the experience in the previous measurement. The same measurement instruments were employed.
WebHighly skewed propellers have been developed to reduce propeller-induced vibrations through a softer interaction between the propeller and wake. An account is given of the studies which the KaMeWa Marine Laboratory has, over the last few years, carried out on c.p. propellers with large skew angle.
