Three and Six Degree of Freedom Trajectory Simulations,The simulation of flight trajectories of space vehicles requires the knowledge of the various forces and moments which act on these vehicles. Forces and moments are produced by aerothermodynamics, propulsion and reaction control systems, and gravitational fields.

Numerical Applications of the General Equations for Planetary Flight,This chapter is devoted to the discussion of simulation results of several space flight scenarios ranging from movements in Earth or planetary orbits via aerobraking and aerocapturing missions up to re-entry problems, and also of artillery ballistics.

Our Planetary System,Our planetary system, with the Sun as central body, embraces nine planets. The characteristic data and orbital elements of these planets are very different. In Tables A.1 and A.2 a selection of this data, mainly taken from to , are listed.

Other forces and moments are given by propulsion and reaction control systems, which are needed for the ascent to a space orbit or even for leaving the gravitational field of a celestial body as well as for any trajectory manoeuvres in space.

Sustainable Practices in Italian Businessesre-entry processes as well as artillery ballistics. We therefore provide in this chapter some basic features and properties of the Earth atmosphere, and some velocity-altitude maps of flight parameters and re-entry vehicle trajectories, following the presentation of this data in .
