abstract
This paper presents a novel approach for the analysis of uncertainty propagation associated with hypersonic re-entry by a spacecraft. The well-known cell-to-cell mapping technique for the analysis of uncertainty in dynamical systems is combined with a heuristic algorithm for domain discretization, that can significantly reduce computation efforts associated with the method. This is used to analyze the propagation of distributions arising from uncertain initial conditions in the hypersonic re-entry problem. It is shown that the results compare very well with Monte-Carlo simulations for initial conditions sampled from multivariate probability density functions for the initial conditions. 2008 by Prasenjit Sengupta and Raktim Bhattacharya.
