| Abstract: | Existing predictional methods and experimental data of aerodynamic characteristics for elliptical cross-section bodies have been reviewed and analyzed. A predictional methodology based on Jorgensen method and experimental data is described , and the corresponding software of the methodology have been worked out. The angle of attack can be up to 90 degree. Computed results for several configurations are well conformed to experimental data. |
