CALCULATION OF POTENTIAL FLOW ABOUT ARBITRARY THREE-DIMENSIONAL LIFTING BODIES

The report describes work accomplished during the second phase of a projected three-phase effort to develop a computer program to calculate potential flow about arbitrary three-dimensional lifting bodies. The main task of this phase was programming and checking-out logic that had been developed previously. Evaluation of the method by numerical experimentation has just begun, and the few results obtained so far comprise the body of this report. Simple wings of rectangular planform are considered. Preliminary results indicate that surface pressures are insensitive to wake shape but sensitive to the means of applying the Kutta condition. For some situations there is an anomaly in the surface dipole distribution, which fortunately does not affect the surface pressures.
