文摘

On January 20th 2004, the engine of the third stage of a Delta-II launcher reached the Earth’s surface in the province of Corrientes, Argentina. As we were aware of the orbital data before entry as well as the location of the point of impact, we then refined a proper trajectory simulation 6D code to propagate the solutions of dynamic equations of state up to the encounter with the surface. During this propagation, the aerodynamic state is continuously adjusted to changes in the regimes of flight. When simulating the reentry, a possible trace of impact is obtained where it is estimated that the object will fall. The present work compared the effects of two atmospheric models: the static model USSA-76 versus the dynamic model NRLMSISE-00.
