In all cases, you would need enough thrust to remain along that vector. An increase in max flight speed would likely still not allow you to use only atmospheric thrusters, get maximum speed, and rely on momentum to push you through the atmosphere without that speed increase being well above what the game engine allows. The thinner atmosphere would also limit this sort of thing greatly as you would need to build speed while within the denser part of the atmosphere then change vector to cross into the less dense part causing some loss of your initial velocity.
Thanks for your answer.
But if you read my question: I would be using a speed mod to allow me to achieve any speed i need in order to rise out of the planets gravity well.
Though you are right, and i did not think of it in this way - But then again, the increase in speed is somewhat only marginal due to how quickly gravity of the planet will let up and the angle at which i fly.
The speed curve would be a cute little speedbump and then flatten back down to the games default 110 m/s, even at a 45 degree ascend angle.
Of course, if one where to constantly rise yet also follow the curvature, and using hydrogen engines, i would no use as much fuel as if i were to fly a straight 45 or 90 degree angle from the planet. Or maybe i would, since i would need to fly for much longer... so i guess that would even out the required fuel in the end anyways...
My math might be a little suspect, but I believe that about 830m/s should cover you for earth and about 870m/s should cover you for the alien planet.
There's probably a decent margin of error on this, but given that the way I did my math is likely to lowball the figure a bit, you should definitely consider these to be minimum speeds and possibly aim 10-20% higher.
I don't know if that is normal speed for a rocket, to lazy to google that, i just want to go back and lay some more Space Engineers.
I mainly asked to try and learn something, and i learned a lot. First of, i need speed mods if i'm to enjoy this game... 110m/s from the Terran planet to the other takes... hours... wtf... So Speed mods is a god send. Midspace's speed mods is where it's at...
Talking about velocity, you would be talking about a situation where you are getting up to speed, then turning off dampeners and potentially ceasing all other thrust (such as trying to get to space with atmospherics only). The way the game handles angular momentum without any handling of lift, gravity will start pulling you down the moment you cut your dampeners, this will change your arc so if you are not at a steep enough angle, you will just start circling the planet until gravity finally wins out. The area between dense atmosphere and where gravity stops having much effect tends to be larger than you could normally cross on momentum alone unless going at a fairly steep angle.
With a speed increase, the simulation still has to be able to acknowledge your vector and positioning accurately or may translate your forward momentum into downward momentum more quickly than it should.
In short: Strap a rocket from ACME to my back and lit the fuse and go 9k m/s and unstrap from rocket in time otherwise it'll be a while before i respond... XD
Wasn't sure if you meant real-life Earth or the earth-like planet in game. For Earth, escape velocity is a little over 11km/second.
Don't think the physics works realistically enough.
From the Terran planet to the other... Wait, are you travelling between planets without jump drives?
hehehehe
The answer is YES... because i keep forgetting they exists x.x
LOL! Glad I helped you remember, all the time you'll save
Given your chosen escape vector, you'll need to travel ~70km (i estimate) to get outside of the influence of gravity.
And given an average deceleration due to gravity of approx -4.9m/s
To reach the given distance of 70km your initial speed needs to be about 830m/s (~2988km/h)
Like I said, oversimplified version of the actual required calculation (also with slightly suspect math), so definitely aim for an initial speed a bit higher than that.
I'm not exactly sure what the escape velocity on real earth is without googling it, but off the top of my head I'm pretty sure it's at least an order of magnitude higher than the speed you'd need for SE. (~20,000km/h if memory serves)
Speed mods, that's where it's at hehehe ;)
