Spaced Out

@K^2 Are there any sort of simulation websites or tools I could use to try out exact optimization just because? Also if you don't mind could you elaborate more on the first part of your reply? I'm just a bit curious about this part.

Are these the criteria for the nost efficient ascent profile possible? 1. It is a gravity turn to reduce cosine losses. 2. You want to be turning horizontally at a rate where you get as close as possible to failing due to heat or aerodynamic stress or to your safety parameters for those things so that you reduce gravity losses for the entire flight. This is because the more horizontal you are at any point, the less of the delta-v you are putting in is able to be taken by gravity, and as you turn less of your delta-v is used for vertical velocity which isn't needed for getting into orbit, so more of your delta-v is used for horizontal velocity which is all you need for orbit. 3. You only want to throttle at Max-Q during the beginning of ascent because that is the point with the most aerodynamic stress and drag, and both of those things go down very quickly after it. And if you throttle any other time which would probably not be necessary, you lose delta-v from gravity. 4. You want to be at full throttle because you are unlikely to hit terminal velocity during the slow parts of ascent in the low parts of the atmosphere, and not in the high parts either because the atmosphere thins so much and until you are mostly horizontal you just waste delta-v to gravity by throttling which is worse. If I got anything wrong please tell me, and if you have any other insight please tell me that also. Also are there any scenarios where another sort of ascent profile is better than a gravity turn too?

What do the Hold AP time start and finish do and how do they affect the launch, also if I don't want them on how do i turn them off?

By maximum delta-v, I meant for an all-purpose vehicle, but thanks for the tip.

How many and what size for each? I know that one large 1st stage and a small but efficient second stage is great but is there any better configuration for maximum delta-v?

I am going for an all purpose launcher though for heavy lifting. Any tips for max delta-v that have to do with the topic of my questions?

A couple questions. 1. How much of the total delta-v of my launch vehicle should the 1st and second stages have respectively? (e.g. 1st stage 1/2, 2nd stage 1/2) 2. What is the optimal mass comparison between the two for maximum delta-v? (e.g. 2nd stage is 1/4 the mass of 1st stage) 3. Should I design the 1st stage first or the 2nd stage and build the 1st stage around that?

Granted, but before you can take a bite you get shot by the pizza police because your pizza was illegally obtained. I wish that I was on the ISS

Okay guys thanks! Got it working.

If you sat in an office chair and fired an AK-47 that was placed so the thrust from recoil would be directed through the Center of Mass, how far would you move per shot?

Okay so I would like to get the most efficient ascent possible, what mod could calculate the most efficient trajectory and fly that?

Okay so I can't install Mechjeb, I have Windows 10 if that helps. Also I didn't get KSP on Steam if that helps too. I tried placing it in the GameData folder and Squad folder but neither worked. Any ideas? My version is 1.3

Could this possibly be used on one of SpaceX's Mars capsules?

Thanks for answering, but I have another question. Don't you just need an initial pitchover, not manual control?

Can you explain this a bit more? I don't really get what you mean. Also can you explain this a bit more too?
