See the discussion on misc posts for more info No posts unrelated to KSP or memes and image macros. Please remain kind and civil at all times To sum it up I dont have a table with 50 numbers. If you have low thrust to weight ratio you must climb more straight up to give the engine time to push the rocket up to enough speed before the mighty G bends the trajectory so it points back to kerbin. The thrust to weight ratio is more important and your ability to accelerate. Originally posted by maj.solo:It does not affect anything.

It is only the launches to LKO that need some skill. you need no second stage you just coast op to 300K or add a little throttle and inch your way up to 500K before circularizing. Kerbin have no chance in hell to bend your orbit the orbit will become very 'stiff' and when the kickbacks burn out nose might have dropped to 50 degree and you are at 35K doing 2200m/s. TWR is like 2.5 but in the end it rises to 7 8 9 or more. Turn as hard as you can and bend nose down to 55 - 60 degree. So instead of going shallow I usually blast off with a giant kickback stage. circularizing at 500K is fine by me I dont care. If I am going to minmus I say I dont care where I end up. Since you started so steep it will not be 30 degree 1000m/s at 30K - 35K rather maybe something likeīut all this is if you want to end up in LKO at 70K - 80K.

Will you be able to get to 1000m/s before nose have dropped to 30? if not then you need to go full throttle when you are pointing at 55 - 60 degree. As you approach 45 degree you need to know your max TWR at that point. Start throttling back to just maintain 500m/s and let the nose slowly drop Keep SAS hold wait to confirm positive climb 100m/s or so. Keep SAS hold, tipping the nose at low speed low thrust to weight is very bad. Same arc have to be done with rockets with low thrust also. As soon as you are doing 500m/s select SAS prog grade again.Īnd as I wrote next checkpoint is 30K - 35K, 30 degree, 1000m/s.Ī veeery dragy rocket you want to go into thinner atmosphere. If you have thrust to weight > 2.0 you will soon be doing 500m/s this was just an example of a little incident that might happen. If the flight path marker is dropping to 45 but you not yet at 500m/s select SAS stability to resist dropping nose further. So a fast slender rocket I might fly like this

Never drop the nose below 30 degree unless you are doing 1000m/s and have TWR > 1.5. Never drop the nose below 45 degree unless you are doing 500m/s and have TWR > 2. I personally also have some critical numbers/points that I dont want to cross. So a rocket with much drag you might want to climb up more into thinner atmosphere before accelerating sideways. Then ontop of this basic problem there is aerodynamics and fuel economy. No way here mass of the rocket has any importance only your ability to accelerate. And when you are fast enough the rate at which kerbin bend your trajectory is offset by the planet being round and curving away under you so you get an orbit. If you have good thrust to weight ratio 2 and above you can point more to the horizon cause you will be gaining speed faster and the faster you go the harder it is for Kerbin to bend your trajectory towards the ground.
