If you want to look at a bit of silliness, here's me putting my Space Harrier through the Kerbin atmosphere at transsolar velocity. Five takes, for 50Km to 10Km perigee. This is with the FAR mod.

If nothing else, the flames and explosions are pretty.

Speaking of mods, I tried out the SKLYON mod for this, seeing as I found that while searching KSP stuff.

I'm pretty damn sure the real thing doesn't have THAT much specific impulse. Not that I mind the silly atmospheric impulse, since that's kind of the idea. It's the silly impulse in vacuum that bothers me a bit.

Playing with it anyways, though. SSTOs are so much easier without flameouts

Remember folks, to deal with your high-altitude jet burnouts, always add a central jet engine, and add it LAST.

Jet engines all dip from the same common IntakeAir pool, and they each take the totality of what they need before the next placed engine gets any. So, placing a central jet last will have it burn out first, warning you about low air without throwing you into a spin.

Or if you're feeling like being funny, mount all your jets on the center axis.

Or at least near it.

You may recall the 1680 m/s balloon-plane with two turbojets on a vertically-oriented bicoupler. Ah, those were the days.

Meanwhile, I'm totally going to make a space factory! Because who needs SSTOs when you can build giant things in space?

First I have to learn to dock, though. :V

Oh damn this explains so much, I will have to revisit some of my failed experiments.

Yup:
Kerbin TWR 2 = Mun TWR 12

That's why you are finding such low values for TWR Nao: you are forgetting dividing by 0.166

Actually its the opposite. It's because the numbers are so low i try to tell people they are flying inefficient landers . Although it's more about the lack of smaller but efficient engines.
I actually tried ascents with a 30ton craft and one LV-N resulting in 2m/s^ acceleration = 1,25 Mun TWR and it worked as was calculated in the charts.

We could have a challenge to do a stock tourist mission to Mun! Bring 8 hitchhiker storage containers to the Mun surface and back to Kerbin. (Mk2-lander cans would be an same mass alternative). The lowest starting mass wins, jet engines not allowed for kerbin ascent, control and visual mods would be ok (mechjeb etc.)
I'll try doing this mission during the weekend. (Maybe ill post this challenge later on KSP forums =3)

Cheers!

edit:

SSTO's are hard :<

SSTOs aren't hard, you just have to make them a little silly.

This man is right (sorry for repost but if fits perfectly)An SSTO with more silly and less jets.

Because I suck at using the orbit map and that ball thing, what would be a good landmark for orienting myself with the cardinal directions during takeoff?  Also, would it be better to go with the rotation of the planet, or go against it?

Well, if you don't rotate your craft when designing it, turn to the right when you're ascending. Going east like this essentially gives you free velocity when you make it into orbit.

In other words, tilt directly away from the VAB, towards the water. That moves against Kerbin's rotation.

Introducing my Hercules Tug, which I'm assembling in orbit as my interplanetary tug for moving things between orbits(not really interplanetary, but it WILL get to the mun and Minmus and back). Here it is with two out of 4 engine arms completed:




Edit: I've also created a reusable skycrane for ferrying things from  Mun/Minmus orbit to the surface. Does this have enough thrust to say, get a full orange tank there, or do I need more engines?

[da_nang]

Jeb's face... My god, what is he doing?!

[tryrar]

.......Dunno lol.

Here's the completed tug+skycrane:



Now to create practical kethane mining rigs+storage tanks to ferry to Mimus....

[Chattox]

Why do you have an ion engine on the back of a liquid fuel tank?

[ank]

@Nao
I am going out on a limb here, but i am pretty sure that adding more radial engines would make for at more efficient ascent, because only 20% of the fuel is going into gaining velocity, the rest is wasted on gravity drag.
If you post your craft, I'll try and fiddle around with it.
