Symmetric separated flow past slender bodies at angles of attack in subsonic and supersonic flows

A prediction method has been developed for determining the normal force and pitching moment on bodies of revolution both in subsonic and supersonic flows at angles of attack upto the onset of asymr- metric vortex shedding. The analysis assumes that the force on the body is the sum of inviscid and viscous contributions. Woodward's three dimensional panel method is used for inviscid flow calculations. In the viscous analysis the contributions from the shed vortices and the feeding sheet are accounted for separately. Comparisons are made of the predicted values with available experimental data on a representative ogive cylinder body.
