A Comparison of the Effects of Four-Blade Dual- and Single-Rotation Propellers on the Stability and Control Characteristics of a High-Powered Single-Engine Airplane

Abstract

A 3/16-scale powered model of Douglas X3B2D-1 airplane was tested with no other changes on the model than that of changing propellers. Characteristics of model were determined for a number of operating conditions for each type. Longitudinal stability was with dual-rotating propeller. Directional characteristics were most affected by change in propeller type, but no marked difference was found between lateral characteristics. Primary changes in characteristics were due to removal of rotation from slipstream.
