Hi all, I'm searching for a while how to calculate the duration of a burn required to change orbit both for the Hohmann transfer maneuver and for circularization maneuver. I'm using KOS in KSP and after launch I have periapsis at about 85km and apoapsis at around -200km. At this point I want to write code for orbit circularization. So from my understanding I should burn until my speed at perigee will be equal to the speed at apogee and this will mean that I have close to 0 eccentricity. I wasn't able to find the calculations needed to get the deltaV needed and the burn time. C

I am trying to do a mission to a planet with life support (USI), and I would love to know how to find the time it would take to reach that planet so I could balance my habitation and resources accordingly.

Hello! Firstly, I know questions like this one have already been made both in and out of the forums before, yet every thread I found and read do not fix my problem or give me an idea of what I'm doing wrong. Also, sorry if this ends up a bit too long and technical, I want to try and make it as clear and detailed as possible, especially when explaining the math I did, so it doesn't confuse or give the reader a headache. So... I finally decided to play KSP [more] seriously, disabling "revert flight" and trying to calculate the rocket performance and everything else before launch

I have an equation that shows the target speed you need to reach to have a successful hohmann transfer: V = 1878968 * sqrt(2/RInitial-2/(RLowest + RHighest)) It's always worked in the past, but I recently tried to use it to find the target velocity for a transfer around the sun. When I plug in the numbers, I get a ridiculous answer of 16 m/s, and I don't know why. The weird thing is, I tried looking this formula up on Google to see if I missed something, and I cannot find it anywhere. Has anyone else used this formula?

Hi Everyone, I've been working on a spread sheet in Excel, for various calculations relating to KSP. This is firstly, to learn more about the Physics and Math involved in KSP [and Space flight in general], and secondly, because I was thinking of starting a Barebones Career, as in only adding parts and planets in terms of mods and not anything like KER or Mechjeb, and possible doing IVA only's. [not sure if I'm that confidant with my KSP skills yet though ]. So far I have: - Hohmann Transfer Bi-Elliptic Transfer Interplanetary Transfer Satellite Min

Hey everyone, I recently have been sucked into this game, and I'm loving the math. My question is this simple, determine the altitude a rocket will achieve on full fuel burn of a single stage. I've done a lot of research and have come up with the following example problem to test my algorithm/process of calculation. Let me know what you guys think of below and what I'm missing or potentially a force I haven't considered into the calculation such as lift, as you'll see my answer is off by nearly 3,300m. (For the sake of simplicity the rocket travels straight up in a vertical dimension only.)

UPDATE: New thread created for 3D model that does everything this model does and more. Original post below: I've been exploring optimization solutions lately for my interplanetary communications network, and was having a hard time wrapping my head around some of the math and picturing the system in my head. So I did some research and learned some equations and relationships and found a nice free graphing software to bring it all together. I worked out the polar coordinate equation for each planet's elliptical orbit and plotted it. What came of the exercise was a scale model of the Ke

Hi, I'm not new to Kerbal Space Program but I still don't know one thing. I don't know how much Delta-V I need to get to a planet or moon. If someone could tell me how to calculate the amount of Delta-V I need I would really really REALLY appreciate it. Thanks for looking at my post
