Hyperbolic interplanetary transfer

  1. Jul 13, 2004 #1
    Could someone tell me if I'm right or wong...

    I want to calculate de hyperbolic excess speed for a spacecraft that leaves earth parking orbit on a hyperbolic orbit in direction to Jupiter to arrive there in optimum conditions.

    It's not an Hohmann heliocentric transfer!!!

    so, i though that:

    [tex] v_{\infty} = v_{park} - v_{earth/jupiter} [/tex]

    Is it right, or is it worng?

    I'm totally dumb!!!

    Sorry, this tread can now be safely closed (and it only passed less than 10 min)...

    The hyperbolic velocity that I previosly wrote is totally wrong!

    In fact, [tex] v_{\infty} = \Delta v [/tex] where [tex] \Delta v [/tex] is the first impulse from the hohmann heliocentric transfer....

    You could work up a dissertation on the patched conic transfer orbit, starting with a hyperbola relative to Earth and changing over--abruptly or interpolatively?...how does one treat the region where the sun's influence and Earth's are commensurate? -- to an ellipse or hyperbola relative to the sun.
