| Abstract: | This paper presented a numerical method for researching an internal missile separation trajectory from a three-dimension open cavity.Euler equations were solved using the finite volume method.And using the unstructured dynamic mesh coupled with 6-DOF codes computed the separation trajectory and attitude of the missile in three different initial conditions,and it analyzed the reasons of all kinds of phenomena through the variations of the pitch angle and velocity.Finally,it obtained an optimum launch means f... |
