N2 - In order to analyze the influence of altitude on the missile jet flow field, based on U.S. Standard Atmosphere (1976), the point trajectory of a certain ballistic missile was obtained by solving the equations of missile flight without control which is established in the vertical plane, then the technology of secondary programming with Fluent was used to simulate the jet flow field on the trajectory below 30km, which was based on the Navier-Stokes equations and the RNG K - ε turbulence model. The results showed that as the altitude increased, the static pressure and static temperature became lower, mach-number became higher, and the spreading range of jet flow field became farther.
