Comparison of calculated and experimental propeller characteristics for four-, six-, and eight-blade single-rotating propellers

John L Crigler

Abstract

Abstract : The calculated performance of four-, six-, and eight-blade single-rotating propellers has been compared with experimental results for blade angles ranging from 25 to 65 deg. The experimental data were obtained on propellers mounted in front of a streamline body with a spinner housing the hub. The calculated propeller performance was found to be in good agreement with the experimental results over the complete range of blade angle investigated. The method of calculations is presented in detail and a sample computation is included.
