Calculating fast-track transfer windows based on a surplus delta v budget

[Origim]

Hello everyone,

I am wondering if anyone had to perform transfers that are not necessarily hohmann transfers. Specifically, I am wondering -- if I have 5,000 delta v, much more than is needed to get to Duna, when is my transfer window such that I use up all of that delta v getting to Duna (trading efficiency for a much shorter flight time)? If so, the set of derived equations for that would be extremely helpful.

Thank you.

Is that... is that a Porkchop plotter for Kerbal? I must be dreaming right now, because I did not expect to be able to receive the exact answer I was looking for! Thank you very much.

It is indeed. And it works stupendously well.

If you're on Windows, Arrowstar's Trajectory Optimization Tool has a search mode to find the earliest arrival possible with a given delta-v budget. No need to click around on the porkchop plot until you find a transfer you like.
