A review of orbital debris modeling in Europe
Abstract
The importance of mathematical debris models is pointed out. The past debris model of particles larger than 1 cm is briefly reviewed. The objects in this model are composed from two classes: the cataloged objects larger than 10 cm, and the objects between 1 cm and 10 cm, obtained from the simulation of explosions in space. Subsequently the problem of modeling the flux of small particles in the size range between 0.1 mm and 10 mm is discussed. It is supposed that those particles are mainly generated by collisions between a small particle and a satellite. Using the collision mechanisms for such events as developed in the literature, the orbital dynamics of small particle debris is analyzed. The influence of this collisiongenerated smallparticle debris on the altitude range 450 to 500 km (Space Station altitude) is shown to be extremely dependent on the altitude and eccentricity of the orbit in which the collision occurred.
