520 ‡aThe low-speed aerodynamics of a large-scale triangular wing model, with a reduced thickness, tip-turbine driven lift fan in each wing were investigated in the Ames 40-by 80-Foot Wind Tunnel. The model had a 5-percent-thick wing typical of wings designed for supersonic performance.Conventional lift-fan depth has, in the past, limited wing thickness to about 10 percent. A thinner lift fan for the present investigation was obtained by modification of a conventional fan. The modification included removing the discharge stator and reducing the fan inlet length and radius. To control airflow separation resulting from small inlet radii, blowing boundary-layer control was applied through a nozzle in the inlet. Performance of the modified fan along with aerodynamic characteristics of the total configuration is presented. The static thrust performance of the conventional fan (requiring a lo-percent wing) was equalled by the reduced thickness fans of this investigation.--P. [i].
