Three-dimensional numerical investigation into aerodynamic characteristics for a slender body of revolution under strong-source-field disturbance

A three-dimensional numerical investigation into aerodynamic characteristics for a slender body of revolution under strong-source-field disturbance was conducted for the sake of flight security.The problem was modelled as a three dimensional fluid dynamic model and then its governing equations were solved by the verified numerical methods.The solutions give not only the evolution of the flow field but also the aerodynamic characteristics of slender body of revolution,which indicates that the disturbance effects largely depend on both the incoming cruising speed of the slender body and the evolution of strong source field.
