(FMS) can calculate arrival times at tactical points for any airspeed, I like to keep things simple. Ever since flying General Dynamics F-111s out of RAF Upper Heyford in the UK I have planned low levels at speeds as a multiple of 60kt true, to ease the miles per minute...
the planet Mars is selected to apply this method during an aerogravity-assisted maneuver. Several trajectories are analyzed, making use of a drag device with area to mass ratios varying from 0.0 to 20.0 m2/kg, simulating solar sails or de-orbit devices. The mathematical model is based in the...
