Experiments determined variation of thrust with radius by measurements of total head on three air screws with one body, and actual velocity and direction of air stream round one air screw and front of one body by experiments with a yawmeter; results are presented in form of streamlines and of curves of axial component velocity. Airfoil-element theory suggested which would apply to an air screw working in front of a tractor body, involves a single empirical curve representing effect of body on axial inflow at each radius; same curve is assumed to apply to screws of any design or diameter relative to that body.
