Fifty years of the Gawn-Burrill KCA propeller series
Апстракт
The first extensive systematic tests of flat-faced segmental-section propellers were those performed by Gawn in 1953 (open-water tests) and Gawn and Burrill in 1957 (cavitating environment). Since then several attempts to develop mathematical representations of propeller hydrodynamic characteristics (thrust coefficient KT and torque coefficient KQ) have been made in order to improve computer capabilities in predicting propeller performance. The first mathematical model was that of Blount and Hubble (1981), which was soon followed by Kozhuldiarov's (1986) and then Radojcic's (1988). These models were developed through application of multiple regression analysis. Koushan (2007) challenged more than 20 years of the regression approach, for representing the highly non-linear Gawn-Burrill KCA propeller characteristics, and suggested application of the artificial neural network technique. This paper compares the four mathematical models mentioned above.
