I am looking for a calculator or formulas that can be used to calculate the aerobraking on Mars mission.
I have found some data on previous Mars flights where aerobraking was used and all my current formulas applied fail to produce proper results. I do not need very accurate algorithm, just the estimations (something where for given mass, front area (flat), orbit(apo, peri) I get delta-v, heat generated in pass, pressure (N/m&2) in lowest point and new orbit).
