Laythe has a 0.6 atm sea level pressure - it's thinner than Kerbin's.

It starts out thinner but thins out slower, so around 10km on up til almost the edge, Laythe has a thicker atmosphere.

Let's see... so... Junos.... Junos... A Juno is a device for pushing things... push things with the Juno... Push a vehicle with a Juno. A vehicle needs a control point. A control point such as an Octo probe core....

Push an Octo probe core with the Juno...

Push an Octo probe core with LOTS of Junos.

Aha! I have a brilliant plan! It involves 152 Junos pushing on an Octo probe core to 1646 m/s in 1 frame. To those of you who say "this isn't a plane." I say "Depends on the definition of a wing. This thing lifting-bodied itself into the ground within a second of the last screenshot.



A few. Milliseconds. Later:


Slowed down to subsonic without overheating.

I like the out-of the-box thinking

I tried several times to use a ladder instead because that would give it 8 times the force with the potential for a Kerbal onboard. But alas, Kerbals on ladders are finicky and don't do so well under 26000 G acceleration.

Yep. The Junos start to choke when in the intake air reaches mach 1, until the point they get a flame-out.

from the Juno wiki entry

Peak thrust is at about Mach 1.25 - 1.5. At Mach 2 it drops to about 70%, and then falls off rapidly to 0 by Mach 2.5.

Well, só Junos start to choke when the instake airspeed reaches Mach 1.25 (more or less), until the point they get a flame-out.

I was agreeing with you, just with more data.

Yep. And I was fixing my argument using your data!

(language barrier and context-less communication channels bitten us! Was the use of the "so" the problem? Honest question!)

More the overall phrasing. By mostly repeating the last thing you said, I wasn't entirely sure if you misunderstood what I said, or you were being sarcastic, or what.

Well, I decided to give that X1 Stock Mk3D stunt of mine a new shot on KSP 1.8.1

Problem… I lost that crafts on some delete fest, but for luck I had uploaded the Mk3 into KerbalX, so rebuild the stunt was pretty easy.

Taking off with this crap is still a pain in the SAS, the engines flame-out a lot due the lack of air intakes, at bare minimum to minimize drag. Good luck putting her into the air  (once you manage to do it the first time, it's easier).

Well, I think I remade her exactly as the last time, and on KSP 1.8.1 I managed to get 801 M/S. Craft on KerbalX.

Unfortunately, I could not splash the thing once the fuel is out- I messed up and splashed too hard!

A bit more of fuel, and I could try to land it!

Apparently KSP 1.8 gave this thing a bit more juice, I reached 799.1 M/S with 246 Fuel left (I had 204 Fuel when I reached 797M/S on my previous entry).

I think I can extract a bit more from this thing, I will try to figure out how.

I can not believe this thread lasted a year!

[Icky]

now that we've necro'd this thread. 750, level flight, no clipping, 9 engines.
