Wind-Tunnel Tests of a Twin-Engine Model to Determine the Effect of Direction of Propeller Rotation on the Static-Stability Characteristics

Abstract

Static longitudinal and lateral stability characteristics of the North American B-28 bomber were determined during various methods of propeller operation. The results indicate that the mode of propeller operation has a considerable effect upon stability and may also be a factor of propulsive efficiency. The best mode of rotation is dependent upon the flight condition and the configuration of the airplane. The B-28 showed optimum performance with both propellers coming up towards the center.
