Tests to determine to what extent power of rear propeller is affected by motion of fore unit. Three series of experiments were conducted: On two propellers of equal diameter rotating with same speed in same direction; on two propellers of equal diameter rotating at different speeds in opposite directions; and on two propellers of different diameters rotating with same speed in opposite directions. Best tandem arrangement found was forward propeller of unity pitch and rear propeller of equal or similar diameter, propellers rotating in opposite directions.
