| Abstract: | Based on the Mars Pathfinder,the motion stability of Mars explorer in entry phase was analysed,further the effects caused by each of relevant uncertainties,such as center of gravity,entry condition,atmosphere parameter upon the nominal attitude profile were quantified.The results show that the entry vehicle is aerodynamically stable when the Mach number is more than1.2. |
