Full-scale testing/observations
For most propulsion manufacturers it is a normal procedure to check the propulsor designs with regard to their general performance i.e. power absorption, efficiency etc. by analysing the results achieved at ordinary sea trials. The feedback thus obtained is a basic condition for success in future design work. However, in order to obtain more detailed full-scale information required for deeper analysis of theoretical calculations and model test results, several steps must be taken beyond the routines of ordinary sea trials. KHRC has since the mid 1950´s been conducting observations of full scale propeller cavitation for the purpose of correlating with model-scale observations. The full scale measurement methods have been developed further and today KHRC supports the following techniques:
