Abstract : The flow over a body of revolution and its stabilizing surfaces, at an angle of attack, was studied in order to obtain a better understanding of the real flow effects as well as the interference effects between components of the configuration. The velocity field about the configuration, the surface flow, and the pressure distribution were obtained with the model mounted in the wind tunnel of the Ordnance Research Laboratory. Analysis of data showed there is an increase in lift on the body and a decrease in lift on the stabilizing surfaces from that of the isolated components at the same incidence to the flow. The interference effects between components is evidenced by the surface flows and pressure distribution calculated from the measured velocity field. The decreased lift on the stabilizing surfaces is clearly related to the flow over the aft part of the body. (Author)
