Four commercial propellers were characterized over a range of cavitation numbers and advance coefficients. Three of the propellers were then cupped to different degrees on the trailing edge and characterized over the same range of cavitation numbers and advance coefficients. The results show an increase in K sub T, K sub Q, and effective pitch corresponding to increasing degrees of cupping. An empirical relationship is derived between the amount of cupping and the resulting increase in effective pitch. It is concluded that cupping is an effective means of correcting an underpitched propeller, at the expense of efficiency and danger of increased cavitation. (Author)
