The Destroyer Posted October 5, 2012 Share Posted October 5, 2012 Hi, Im looking for an aerobraking calculator. More speficly, I need the height i need to be at jool in a hyperbolic trajectory to get my AP down to 1 million killometers with aerobraking. I tried at 400 km, but ovibusally, that isnt the right height So, what is the aerobraking altitude on jool to slow you from hyperbolic toAP of 10 M killometers?

MaverickSawyer Posted October 6, 2012 Share Posted October 6, 2012 IIRC, the MechJeb Landing Autopilot will calculate such things. Just make sure you are using the delicate setting on your linear RCS when adjusting, and leave PLENTY of time to pull adjustments. Link to comment Share on other sites More sharing options...
phoenix_ca Posted October 6, 2012 Share Posted October 6, 2012 That's a very difficult question to answer, because it's dependant on the nature of the hyperbola. Depending on your relative velocity to Jool, you may need to aerobrake more or less. Link to comment Share on other sites More sharing options...
pwnedbyscope Posted October 6, 2012 Share Posted October 6, 2012 mechjeb will calculate for aerobraking? Link to comment Share on other sites More sharing options...
The Destroyer Posted October 6, 2012 Author Share Posted October 6, 2012 It does? Im looking on how to slow down, not to land? Link to comment Share on other sites More sharing options...
Fuzzy Dunlop Posted October 6, 2012 Share Posted October 6, 2012 Personally I would just quicksave an reload untill I get it right. Link to comment Share on other sites More sharing options...
EvilotionCR2 Posted October 6, 2012 Share Posted October 6, 2012 200/250KM... I use that in my grand tour missions.So it must work Link to comment Share on other sites More sharing options...
maltesh Posted October 6, 2012 Share Posted October 6, 2012 It does? Im looking on how to slow down, not to land?Aye, that it does. Used Mechjeb's landing autopilot dialog thirty minutes ago to find a good aerobrake altitude on Jool for capture, and am now in the Laythe SOI feeling around for the aerobraking altitude to put me into Laythe orbit. If you aren't going deep enough into the atmosphere to force a landing, Mechjeb's Landing Autopilot will tell you roughly what your new apoapsis and periapsis will be after aerobraking.

RoboRay Posted October 6, 2012 Share Posted October 6, 2012 It does? Im looking on how to slow down, not to land?Yes, it does. MJ Landing Autopilot will predict your AP and PE after aerobraking on trajectories that do not reach the surface. I always use it when aerocapturing into orbit.

Guest Posted November 7, 2013 Share Posted November 7, 2013 I was just wondering about this. I was searching for a way to do this without mechjeb or multiple "simulation" runs. I found this just now : http://forum.kerbalspaceprogram.com/threads/24654-Updated-Aerobraking-Calculator?highlight=aerobrakingI haven't tried it out yet, but it looks like a good web-based tool.
