While aerial refueling, the flow field of a receiver changes significantly compared with free stream because of tanker’s wake vortex. This paper discusses the results of CFD simulation with and without jets spouting out of the tanker’s aero-engines. The result indicates that aerodynamic derivative remains while the aerodynamic coefficient changes significantly particularly the drag coefficient and the jets have little effect.
