Highly skewed propeller
WebFor the highly skewed propeller, good agreements of the pressure distribution between the measurements and the theory were observed at the inner region from 70% radial position, while at 90% radial position the measured pressure tends to lower toward the trailing edge and completely differs from the theory. The present full scale measurements ... WebHighly skewed propellers are usually used in warships. The cost for a typical skewed propeller is comparable to that of a conventional propeller.

WebOct 9, 2024 · Using ANSYS to perform a static analysis on the propeller, the stress distribution and blade deformation of the propellers made of different materials at different forward speeds can be obtained using the FSI technique. 3) In the future, more strength-sensitive propellers, such as highly skewed propellers, should be calculated. 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 …
