Abstract : The Vertodyne test program was conducted to determine the static and transition flight characteristics of a wing-submerged ducted lift fan. Static tests were performed. Tests were conducted in ground effect at various heights, and out of ground effect. Forward flight tests were conducted in the wind tunnel. A semi-span reflection plate type model suitable for testing in a seven foot by ten foot wind tunnel was designed. A mechanically driven ducted fan was used, with all drive components contained with-in the basic wing contour. Three interchangeable fan impellors, high pitch, medium pitch, low pitch provided variation in fan thrust. The test set-up was provided with instrumentation which measured forces and moments on the model support and thrust and torque on the fan shroud. Wing surface pressure pickups provided data for a study of surface pressure distributions. The results of the Vertodyne test program are presented to facilitate their application to future studies and designs and to permit comparison with other investigations. Basic knowledge of the flight characteristics of the Vertodyne configuration was gained indicating the direction in which further research is necessary.
