The Propulsion Committee: final report and recommendations to the 25th ITTC

摘要

Details the investigation and findings of the 25th ITTC Propulsion Committee over the period 2005-2008. Tasks were as follows:1. Update the state-of-the-art for propulsionsystems emphasizing developments sincethe 2005 ITTC conference.2. Review the following ITTC recommendedprocedures:• 7.5-01-02-01: Terminology and Nomenclatureof Propeller Geometry (Harmonize with ISO standard)• 7.5-02-03-01.1: Propulsion Test• 7.5-02-03-02.1: Propeller Open Water Test• 7.5-02-03-02.3: Guide for Use of LDV• 7.5-02-05-02: High Speed Marine Vehicles Propulsion Test.3. Critically review examples of validation ofprediction techniques. Identify and specifyrequirements for new benchmark data.4. Review the development and progress inunconventional propulsors such as tip-rake,transcavitating and composite propellers(hydroelasticity and cavitation erosion susceptibilitytaken into account).5. Review propulsion issues in shallow waterand formulate recommendations for research.6. Review the methods for predicting the performanceof secondary thrusters and compare with operational experience.7. Finalise the benchmark tests for waterjets and analysis of the data.
