THRUST AND BLADE SPINDLE TORQUE MEASUREMENT OF FIVE CONTROLLABLE-PITCH PROPELLER DESIGNS FOR MSO 421.

Abstract

An experimental study is presented of the blade spindle torque of five controllable-pitch propeller models, representing five different designs for MSO-421. The study covers a range of both positive and negative advance coefficients at both ahead and astern pitch settings. It was found that the blade with spindle axis located 40 percent of blade width from the leading edge and with uncambered National Advisory Council for Aeronautics Series 66 (NACA 66) airfoil blade sections modified by the Bureau of Ships required the least extreme value of spindle torque.
