Propulsion Committee

1. Update the state-of-the-art for propulsion systems emphasising developments since the 2005 ITTC Conference

1. Comment on the potential impact of new developments on the ITTC.
2. Emphasize new experimental techniques and extrapolation methods and the practical application of computational methods to performance prediction and scaling
3. Identify the need for R&D for improving methods of model experiments, numerical modelling and full-scale measurements.

2. Review ITTC recommended procedures 7.5-01-02-01 (harmonize with ISO Standard), 7.5-02-03-01.1, 7.5-02-03-02.1, 7.5-02-03-02.3, 7.5-02-05-02

1. Determine if any changes are needed in the light of current practice.
2. In the review Review and update of the existing propeller open water test procedure 7.5-02-03-02.1 its applicability to new types of propulsors should be taken into account.
3. Identify the requirements for new procedures.
4. Support the Specialist Committee on Uncertainty Analysis in reviewing the procedures handling uncertainty analysis.

3. Critically review examples of validation of prediction techniques. Identify and specify requirements for new benchmark data.

4. Review the development and progress in unconventional propulsors such as tip-rake, trans-cavitating and composite propellers (hydroelasticity and cavitation erosion susceptibility taken into account).

5. Review propulsion issues in shallow water and formulate recommendations for research.

6. Review the methods for predicting the performance of secondary thrusters and compare with operational experience

7. Finalise the benchmark tests for waterjets and analysis of the data.
