hyperbolic interplanetary transfer

dilasluis

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?

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.
