I coded some Matlab plots of altitude vs time for the re-entry of a point mass (so no aerothermo analysis included). In all the trajectories, there is an S shape closer to the ground. Why? Please could I know specifically in reference to blunt bodies?

    $\begingroup$ This will be easier to answer with an example plot and link to the matlab code being run. $\endgroup$ Commented May 19, 2021 at 9:47
  • $\begingroup$ It should be noted that aerothermal analysis can be done on point masses (just not distributed aerothermal analysis). $\endgroup$ Commented May 19, 2021 at 11:42
