Mission FOTINO: dynamics of movement in an atmosphere

 

Prof. Yury Zabolotnov

 

 

Parameters of capsule: , ,

 - the moments of inertia,

 - situation of the center of mass.

 

The entry conditions:

 - angle of entry in an atmosphere,

 -  initial speed,

  - initial height,

 - initial angular speeds.
