| Abstract: | In order to research the aerodynamic characteristics of one certain projectile in initial segment and obtain the correlative aerodynamic parameters, structured mesh grid is used to build the simulation model. Then the solver for compressible flow was applied to simulate the flow field with OpenFOAM software for obtaining interrelated parameters which are needed in the design of trajectory. After comparing the results calculated with those obtained from wind tunnel experiments, the calculated results are proved to be accurate and can be used in the design of high-precision firing table. |
