Teaching Staff in Charge 

Aims 
The aim of this course is to establish some mathematical models for special topics of theoretical mechanics as the shock (collisions) theory, the mechanics of variable mass systems, the rockets theory etc. Some features connected with the optimal trajectories for the rockets together with the launch of artificial satellites are also envisaged. 
Content 
This course is an extension of the classical mechanics which has been the target of the previous course MM001. The analysis of the collisions phenomena which implies the consideration of unbounded forces (represented by temporary distributions) will be followed by establishing of the equations for the variable mass systems, the rockets and the jets being the most known particular cases. Then the Tiolkovski formulas, the Pontriagyne principle allow us an analysis of different optimization procedures for the trajectories of these rockets within the launch of artificial satellites too.
