BACKING CHARACTERISTICS OF SUPERCAVITATING PROPELLERS

Abstract

The test results generally followed the same trend in the backing condition as in the ahead condition. That is, the thrust and torque coefficients descreased with decreasing cavitation number. The decrease was more pronounced than in the ahead condition and from an examination of the photographs in many cases both sides of the propeller blade were covered or partially covered with cavitation. Considering that th blu railing edge acts as the leading edge in the backing condition, severe cavitation is to be expected. (Author)
