It pretty much requires all the rockets to get up; it's barely get more thrust than weight.

That said, I'm currently testing a 5-body design, which appears to be very successful (and laggy). It should result in longer burn times and higher thrust : weight ratios. It may make for a very good fuel to orbit craft, as the center will be just about full in orbit.

For something like this, you may even attempt some turbojet boosters - just strap some atmospheric engines around the outside and ditch them around 15,000m or so?

I ditch my JATO whosits at 20-30,000

[alway]

So, looks like the 5-body version can make a perfect 200km orbit with over 5k liquid fuel + 6k oxidizer left.

My recent experiments tend towards 15,000-20,000. Higher is of course better, but I'm not good at judging when I need to switch to rockets and/or throttle down to avoid flaming the hell out.

[alway]

So the 5-body model works pretty well.

Impressive!

[Putnam]

Mmm, that is a straight-ass path.

[alway]

Yeah, that was using all fuel, including that in the top stage. Velocity as it left the system was about 7000m/s.

While i dont know much about rocket science, i was thinking if your TWR ratio is not high enough at launch, dont you loose DeltaV due to gravity?

[Girlinhat]

Yes, although I've seen particularly massive rockets that actually lift a few seconds after engine ignite - they have to burn some fuel before they're able to lift, the lowered weight allows them to achieve liftoff.  For most of these, once they do start moving, then they keep moving for a long time, and once they break atmosphere they've got a LOT less drag and a lot more raw power.

[alway]

Yeah; it likely would be better if I removed a layer of fuel from the stacks.


However... Holy balls, found these videos:

Massive orbital carrier + shenanigans.

Just as a note, it isn't the most powerfull space rocket ever flown. Just the most powerfull rocket currently in operation.

All I wanted to do is get a satellite in orbit. I built the core and associated rocket from scratch and launched it. It started pretty well and steady, but once the solid boosters detached and I began my gravity turn the whole thing began wobbling despite Because of an ASAS and winglets.

Sooo awesome.
