Abstract
A low-wing-pod-and-boom combination was found to suffer from almost total loss of lift in the region near the root of the wing. The separated region is almost equal to the tail span. The region of the wing that produces the lift causes an upwash on the tail and results in large static stability, low lift curve slope, and high induced drag. Though sandpaper was used to trip the flow, the size of the model is rather small and a test at higher Reynolds number is needed. Inflow from a pusher propeller is likely to extent of flow separation.
