Detailed Description

Bi-elliptic Transfer.

Bi-Elliptic is a three transfer maneuver to an orbit outside the target orbit (assuming target orbit larger that start), then a xfer back. It can be lower dV (but longer time) than Hohmann for some rf/ri. e.g. if rf/ri > 11.94 and xfer_radius is very large will be better by less than 10%. (see https://en.wikipedia.org/wiki/Bi-elliptic_transfer)

HasLowerDv()

static bool BiellipticXfer.HasLowerDv ( OrbitData  fromOrbit, OrbitData  toOrbit  )

static

Check to see if a bi-elliptic xfer can produce lower dV. In many cases the time required for the BE xfer may not be practical.

Routine imposes a limit of 13 for r2/r1 (for which transfer orbit is 48.9*r1)

Parameters
