The solution of three-dimensional Navier-Stokes equations is obtained and used to study the aerodynamic interference between a propeller and an empunage. Results show that this interference is quite important, especially when the components are in ground
effect. The propeller should be positioned in such a way to reduce the negative aspect of the interactions while, at the same time,
keeping the lift and drag within an acceptable range. Using computed flow fields, the proper direction of the propeller, regarding the above criterion, is determined. In this study, the flow field around a propeller- empunage combination in ground effect, using 3.1 million cells on a cluster of workstations, is obtained and presented.
