mubody.core.kepler.DeltaV_fb#

mubody.core.kepler.DeltaV_fb(rper, Vinf, mu)#

Delta-v obtained during a flyby.

Calculated from the Vinf of the incoming trajectory and the periapsis radius of the flyby trajectory.

Parameters:

  • rper (float) – Perigee radius [km]

  • Vinf (float) – Hyperbolic excess of velocity [km/s]

  • mu (float) – Standard gravitational parameter [km3/s2]

Returns:

DV – Delta-v gained by the S/C [km/s]

Return type:

float
