Abstract

An apparatus for testing an implement having an elongate shaft with a head end and a grip end, with a head attached to the head end. The apparatus may include a wind tunnel with a test cell adapted to receive the head of the implement and permit a range of unrestricted movement of the head within the test cell. The test cell includes an inlet and outlet for air flow and a portal or opening in a wall of the cell to which an elongate conduit is attached. The conduit extends in a direction substantially normal, or radial, to the direction of airflow. The conduit is adapted to receive the shaft of the implement, with the grip end of the implement extending beyond the far end of the conduit and into a clamp. The clamp is adapted to hold the grip end of the shaft in a fixed position.
