In my head the Kerbals were artificial life forms created to serve on generation ships. The ship crashed, the passengers died, but the Kerbals survived. They pursue space flight so strongly because space isn't a new frontier. It is home.

Funny you should say that.


That was from the next flight. It was an experiment to see if just flying straight up then trying to circularize would yield better results. It was only a suborbital shot, so flying spaceplane style was better.
That being said spaceplanes without wings, let's call them horizontally launched rockets don't seem to fare too much differently to planes, which is a bit sad.

RAPIERs are too inefficient. Pretty sure it'd only make an elliptical orbit before the juice runs dry.
It's predecessor had wingtip mounted nuclear engines. I was going to start experimenting to see if this plane would support them. It could potentially be a useful Eve lander with some modification.

Ohh... Magic School Bus!

I think perhaps the Kerbals are something like worker drones spawned by some sort of queen or main biomass deep underground. They built the KSC nearby for convenience.
Infrastructure isn't really needed because Kerbals are spawned as needed and imbued with knowledge from the queen during creation.
Subterranean resources are easily collected as it is their place of residence. However technologies developed by past individuals are scattered around KSC mostly due to unfortunate circumstances. in an effort to conserve resources and keep their planet pristine they opt for recycling over mining / refining.

In the game we are yet to see a Kerbonaut take root in the soil and begin transformation into the seed of a new colony as their spacesuit prevents contact with the ground. It also handily prevents suffocation.

You can get some pretty big numbers before the engine decides you're in an escape orbit. Repost of something of mine from a previous thread (This was like version .15 or somesuch):



Long story short: I wanted to get a Kerbal as close to Kerbol as I could, but keep it in a circular orbit. Solution: bi-elliptic transfer orbit, with a periapsis as far out as I could take it for maximum fuel efficiency.

Check out the time to periapsis listed by MechJeb on the left. That 8.775*10^12s or about 159 thousand years.

No, seriously don't. Personalities for the kerbal individuals are great (btw when you introduce girlbals you need one that has some sort of special personality ala Jeb), personality & backstory for the rocket parts companies is fine, but the big questions should just be a blank.

What are the Kerbals?
Why are they so gung-ho about space?
How do they operate a space program on a planet otherwise devoid of structures or life?
Was Wernehr von Kerman really a war criminal before leading the Science program? Official answers to these questions are always going to be worse than the empty canvass that each player can fill themselves. I'm sure some players are unhappy that there's no explanation for any of those questions, but those exact same people will still be unhappy afterwards because some bits that are inconsistent or there are still blank areas.



In my head the Kerbals have always been the Muppets. The old portrait icons looked particularly Muppet-like, and the loony nature of early KSP fit right in. If Jim Henson had made Apollo 13, there wouldn't have been any explanation for why NASA was suddenly being run by the cast of the Muppet Show.

I do agree with that. Kerbals just are. It's fun to speculate. It also helps a lot with sandbox mode. I play mine closer to Sci-Fi, with Kethane mining and ridiculous ships. That doesn't fit with people that play it "real" etc.

One thing that does bug me is how barren Kerbin is. Besides the airfield and the other Space Centre if it even exists still there's nothing. It's kind of lonely.

Get rid of the scoops. Only use ram air intakes. Scoops work best at low speeds.

May 14, 2009
Also, abuse parts clipping to cram four ram intakes together. (alt+f12 in assembly)




Bind the intakes to an action group while you're in the assembly hangar, close them when you engage the rockets to reduce drag a little bit. Mostly you'll just want to use jets up to ~18k, flatten out and pick up speed until you're pushing around 1.2k m/s at just below your flameout threshold (around 22-23km works for me), then point upwards at 45 degrees and use rockets.

Despite what the description says, all scoops function the same at various speeds & altitudes. The only difference between them is Intake Area which is a linear multiplier. 1 ram intake = 1.25 circular intakes = 2.5 radial scoops. A plane with 5 radial scoops will have the exact same performance as one with 2 rams, for all condidtions.

They all mass the same so ram scoops are theoretically far more effective by mass, but they also require nodes to attach to. If you use cubic struts to stick them on you come out ahead, but if you care about aesthetics enough to use bi/tri/quad couplers it's a net loss compared to just sticking on more radials.


A couple radial scoops are nice to have on any spaceplane though, because they store more units of air. You get a little more time at high altitudes as they drain the storage, and more warning before you flame out.

Same. Also because they look super-dumb up close, if you're landing a ship or flying a plane.

In a world with infinite developer time it would be neat if there was more stuff on Kerbin, but on the list of things I'd want real work put towards that is way down the priority list.

The Rotating parts are from Infernal Robotics, and the aircrafty parts are from B9 Aerospace.

It also controls well when the rotors are feathered, and can even autorotate.

That's all fine and good, Except that the scoops have less intake area, and the same amount of drag. So by using the ram intakes in the place of scoops, you cut your drag by more than half vs using just scoops because you need fewer rams then scoops.

Scoops become dead weight at lower speeds and lower altitudes. There is no reason to use them, especially when you can slap them onto a cubic octagonal strut and place them anywhere.

Mine, yes, because I'm purposely spinning the entire craft. SAS tries to fight it, but SAS is also trying to fight a spacecraft that is spinning. It eventually gets to the point of flinging engines or parts and then you get into the whole unbalanced-thing-spinning-quickly part of disintegration. Otherwise, on normal rockets I've only really noticed small rotations when something is slightly out of balance and SAS can stop it.

When intakes are open, they have much higher drag which also is defined by intake area. So for pretty much all of the time that drag matters they'll have near-equivalent drag. I'd put part load as a bigger factor in the ram scoop's favor.

Yeah, except that the game is easy enough without doing stuff like that. One of the ways I keep it interesting for myself is to reject anything that looks dumb. I put on some rams in places where they look good, I don't abuse clipping except for aesthetic appeal, and add some scoops because they're easy to blend in. You can do whatever you like, but you might be surprised how little difference there is outside of crazy air-hogs that can achieve orbit with a single turbojet.




Re: the question about gyroscopic forces -- I think a Triebflugel / tip-jet gyro should behave like a gyroscope when it's spinning. The game should replicate everything that comes naturally from newtonian mechanics. There's an old Manley video where he uses InfernalRobotics rotatrons to make a reactionless orientation system for a telescope. No RCS, no torque parts, nothing but pure physics. Similar principle. IANA physics simulation programmer though.

Seeing gyroscopic precision in action on those aerial contraptions might be difficult with all the other forces going on.
