| Résumé | Cavitation characteristics for a family of skewed propellers were obtained by using an in-house panel method code PROPELLA. The propellers used were the existing NSRDC (US Navy Ship Research and Development Center) skewed propellers. Detailed geometry, open water test data, and results obtained from physical cavitation tunnel tests for these propellers were taken from published literature. Predictions were completed using appropriate wake data (either uniform inflow or measured wake survey data) to determine individual blade spindle torque, in-plane and out-of-plane bending moments and their fluctuations in both open water and behind-ship conditions. For the design speed, cavitation performance was assessed in both the open water and behind-ship conditions to determine thrust and torque breakdown. |
