Abstract

© 1997 American Institute of Aeronautics and Astronautics, Inc. All rights reserved.The NASA-Ames developed panel code, PMARC, is employed to compute subsonic flows over an ogivecylinder body with an overall length of 7.5 diameter. Flow separation is modeled by vortex wakes attached to the base region and the leeward sides of the cylinder body. The computed surface pressures, and integrated normal force and pitching moment coefficients are found to be in good agreement with the experimental data up to 20° incidence. This favorable agreement suggests that the panel codes may be a computationally efficient tool in aerodynamic missile design process at low incidences.
