Equations for Gravity Assists?
Space Mailman posted a topic in KSP1 Gameplay Questions and Tutorials
Hello! I’ve been playing KSP for a while now and have become quite confident in my abilities. Although, I’m still having trouble with gravity assists. Is there an equation of some sort that I can use to calculate my speed after the slingshot/brake? Ex. Before assist craft is going x m/s, after the assist the craft is going y m/s I also would like to know if there is an equation I can use that will tell me the orbital velocity at a certain altitude above a body. Ex. At h meters with d degrees of inclination, the craft must be going x m/s to maintain a circular orbit If you have any other useful equations that would be nice, thanks! -
I have been looking at the following, to try to understand what I am/can do in KSP more. However some of the Equations are missing/not showing up. Does anyone know what they should be?

Hello! I have been wondering about manually calculating the rocket/objects/bodies statistics on paper rather than using mods. I love KER, but I am looking for a way or a style later on where I don't rely on it to design my rockets... (And maybe later if I got the time, make small plugin that only shows the required information from the rocket to take them and do the TWR, dV, burn time, etc... calculations manually). I tried to make the calculations on a sheet, but they were way off the actual numbers shown in KER. I had a rocket in KER showed 11k dV, while on my sheet it was showing 14k dV, so I was wondering what KER takes into account when calculating the numbers? The way I did it was to calculate the stages I know will be in atmosphere based on the Isp in atmosphere for the engine, then for vacuum stages, I used the Isp for vac.... Is it how KER do the calculations then takes the average or am I wrong? I am looking to get the calculations correct as I want to remove KER and just use my own calculations and to improve my math as part of my math re-learning program Also, I am looking for these equations: The set of equations to calculate launch profiles and ascent paths for rockets, also planetary transfers and windows. One other really PITA thing I have is determining the landing trajectory of an object. I use the mod Trajectories which is awesome, but again I want to do it myself... Really appreciate your feedback!
