Aerodynamic Characteristics and Kinematic Analysis during Turnover of a Reusable Sounding Rocket

Flight capability of a reusable sounding rocket during turnover was investigated by numerical analysis. In this study, we first carried out the numerical flow simulation to obtain aerodynamic characteristics in turnover maneuver, and then solved kinematic equations of a rotating rigid body using obtained dynamic characteristics. Although the body for research is a simple baseline shape, and parts of aerodynamics, fins, strakes, canards and so on are not attached, simulated flow conditions are based on a real flight. From the results, we could evaluate basic flight capability of this rocket in turnover maneuver.
