Investigations into the use of a cross-flow fan as a potential source of propulsion and lift have arisen due to the cross-flow fan's geometry, light weight and safety by shielding from bystanders. The application of a cross-flow fan as the propulsion source for a fan-wing vertical takeoff and landing vehicle has drawn attention in recent years. Previous investigations have demonstrated the performance characteristics of multiple cross-flow fan configurations. During this experiment a cross-flow fan with 30 blades, a 6 inch diameter and a 4 inch span was tested. The performance and stall characteristics were determined and plotted along constant speed and constant throttle setting lines. Comparison of the tested cross-flow fan was made against two previously tested cross-flow fans with similar design and 1.5 inch and 6 inch span lengths. Performance parameters of the three cross flow fans were compared and plotted for constant speed curves. The results allowed for general trends to be determined and scaling laws to be deduced.
