OPTIMIZATION OF CROSS FLOW FAN HOUSING FOR AIRPLANE WING INSTALLATION
Abstract
The research dealt primarily with the optimization of the cross flow fan housing for its installation in an airplane wing. A cross flow fan was installed in a NACA 0018 wing section and various housing shapes were tested until a housing shape was obtained that trapped both the primary and secondary vortices, so that maximum throughput could be obtained. For this wing section, data was collected and the pressure coefficient distribution on upper surface was obtained. There was a significant rise in the absolute magnitude of pressure coefficient distribution on the upper surface with the fan running. Momentum coefficient values as high as 1 were obtained, which implied that such an arrangement could be used in an airplane to improve its STOL capability.
