A rotor blade for a reaction drive type helicopter includes a proximal end couplable to a rotor hub and a distal end terminating in a blade tip. A hollow passage extends from the proximal end to the distal end for ducting air/gasses from the rotor hub to the blade tip. The hollow passage terminates at the blade tip in a duct having an inlet and an outlet. The duct has a horizontal 90-degree bend intermediate the inlet and the outlet, and a plurality of vanes positioned in a spaced apart row within the duct intermediate the inlet and the outlet at the 90 degree bend. Each vane of the plurality of vanes has an inner curved surface and an outer curved surface parallel to the inner curved surface.
