Mutual Aerodynamic Interference Effects for Multiple Bodies of Revolution and Distorted Bodies of Revolution
Abstract
A method of solution for the aerodynamic flow field about two bodies at angle of attack including mutual interference effects has been devised for bodies with circular cross-section. The analytical method used is a modification of a method of solution for the flow about axisymmetric bodies in close proximity at zero angle of attack. As a demonstration of this method, the flows about one, two and three finless M-117 bomb shapes were investigated. Theoretical pressure distributions are presented for the two and three body cases. For the three body case, experimental data is available; however, there is poor agreement with data thought primarily to be because of flow separation along the tails of the bombs. A non-axisymmetric modification of the M-117 bomb shape was developed in order to simulate the flow separation. The analytical results of this effort are compared with the experimental data.
