THE USE OF THEORY IN PROPELLER DESIGN

Moderately-loaded propeller theory, and the corresponding computer programs, have been developed to the extent that theoretically designed propellers are expected to perform as predicted. This development, dependent on high-speed digital computers, allows the propeller designer to investigate many more parameters on a rational basis than he could in the past. Even with these developments, many aspects of propeller design depend on intuitive judgment. Design considerations and necessary design decisions are discussed especially with regard to efficiency, strength, vibration, and cavitation. Also, the theoretical aspects of propeller design are reviewed and the interrelation between lifting-line and lifting surface theory is discussed in some detail. In addition, some information is given on highly-skewed propellers which have excellent cavitation and vibration characteristics and whose successful development depends to a great extent on theoretical design techniques.
