Impulsive transfer between elliptical orbits
WitrynaThe problem of optimal transfer of a rocket vehicle between a pair of coplanar elliptical orbits, employing two impulsive thrusts, is studied. The criterion for optimality is … Witryna19 gru 2024 · A novel simplified parametric model for long-duration impulsive orbit rendezvous is proposed. Based on an existing fast estimation method, the optimal impulses and trajectory can be expressed by only ten parameters whose initial values can be easily determined. Then, these parameters are used to predict orbital …

WitrynaA study has been made of optimizing the 'Hohmann-type', impulsive transfer between inclined circular orbits of different radii. The total characteristic velocity (which is a measure of fuel consumption) is used as the criterion. Two- and three-impulse transfers with a common centre of attraction have been considered, together with the same … WitrynaIt can be shown that when the separation between the inner and outer orbits is very large (r2 > 11.9r1) (a situation which rarely occurs), a three impulse transfer …

A maintenance of a 24-hour elliptical orbit, long-term transfer from a geo-transfer to geostationary orbit, and a one-revolution, medium-thrust transfer between two elliptical noncoplanar orbits are considered as application examples. In the last two examples …
