Delta-v budget is an astrogation term used in astrodynamics and aerospace industry for velocity change requirements for the various propulsive tasks and orbital maneuvers over phases of a space mission.Sample delta-v budget will enumerate various classes of maneuvers, delta-v per maneuver, number of maneuvers required over the time of the mission.In the absence of an atmosphere, the delta-v is typically the same for changes in orbit in either direction; in particular, gaining and losing speed cost an equal effort.Because the delta-v needed to achieve the mission usually varies with the…mehr

Delta-v budget is an astrogation term used in astrodynamics and aerospace industry for velocity change requirements for the various propulsive tasks and orbital maneuvers over phases of a space mission.Sample delta-v budget will enumerate various classes of maneuvers, delta-v per maneuver, number of maneuvers required over the time of the mission.In the absence of an atmosphere, the delta-v is typically the same for changes in orbit in either direction; in particular, gaining and losing speed cost an equal effort.Because the delta-v needed to achieve the mission usually varies with the relative position of the gravitating bodies, launch windows are often calculated from porkchop plots that show delta-v plotted against the launch time.
