Static tests were run with both the 24-in. and 30-in. diameter ducts, mounted in suitable rigging to measure thrust, drag and moments. These tests were to run to investigate various methods of deflecting the slipstream of a ducted propeller and to obtain measurements of the magnitude and direction of the resultant lifting-force. Tests were also conducted to measure the effectiveness of the control surfaces and to investigate the airflow over the control surfaces when the slipstream is deflected by a wing.
