Shuttle 'Challenger' aerodynamic performance from flight data - Comparisons with predicted values and 'Columbia' experience

Skip Entry Trajectory Planning and Guidance

“…For the analytic atmospheric dispersion, based on qualitative Shuttle flight data, [35] it was decided to use a dispersion model with a constant bias and two sinusoidal variations, one with long period, high magnitude and one with short period, low magnitude. Similar density waves have been used in other work.…”
