Interplanetary Math, Part 1: Delta-V

Posted 10-25-2015 at 02:39 AM by PeriapsisPrograde

I have recently taken an interest in doing the math for my orbital maneuvers in Orbiter and Kerbal Space Program by hand. I am mostly writing these down for my own reference (sorry for the sloppy disorganization), but perhaps they will be useful for someone else, so I am publishing them here.

There are many different things to consider when planning an interplanetary trajectory. You need to account for the delta-v and timings of everything for you heliocentric transfer orbit as well...

Universal Grappling Hook

Posted 11-13-2011 at 10:03 PM by PeriapsisPrograde

I might as well try.

Psuedo-code below. UGH would be a vessel dockable to another vessel.
Code:
clbkGrapplingHook (hvessel)
{
if (grappling hook is shot) {find object hit}
else {reload grappler; continue}
vessel velocity relative to grappled object = _V(0,0,0);
get grappling hook vector (hvessel) = vgrapple;
move vessel along vgrapple (speed);
if (object.pos==vessel.pos) break;
else continue;
}

.dll Diving

Screw dumpsters.

I'm never going to do this without some help, so...

I want to make a simple .dll vessel. A simple one. One that could be done via config file. Just to get the hang of it. I sorta know what I'm doing, but then, I sorta don't in C++.

So here goes. I hope Martin is okay with my (ab)using the ShuttlePB sample in the SDK After some minor changes, I have:

Sunrise Spaceport -- Lights

Posted 10-04-2011 at 11:31 PM by PeriapsisPrograde

This isn't really a formal update, but...

I added lights to Sunrise Spaceport. After looking at it, I had to ask. Is it too much? What do you think? See the attached image.

Cheers

Sunrise Spaceport -- Day Seven

Posted 10-02-2011 at 12:58 AM by PeriapsisPrograde

She's starting to take shape!

While some users have been critcizing a 51.6*N location, it remains there at least for now. Does anyone have any specific suggestions?

The list of base objects stays the same for now:
1 -- 3 km runway facing east and west (DONE)
1 -- 3000*50 m taxiway parallel to runway (DONE)
6 -- Connections from taxiway to runway (DONE)
4 -- Connections from taxiway to tarmacs (DONE)
3 -- Tarmacs for hangars, terminals,...
