Re: Kerbal Space Program or "Rocket science is harder than it looks"
yeah, too many boosters just does work.

This morning I made a setups with 12-solid, followed by 3 solid boosters, then triple tank liquid gets into a nice orbit with fuel to spare

Also, using some mod parts, made a pretty cool setup, reliable orbiter

i just said it was ineffitient, but they can and do get you there. sad thing is you can get to the same there with less stuff.
I can no longer sit back and allow communist infiltration, communist indoctrination, communist subversion, and the international communist conspiracy to sap and impurify all of our precious bodily fluids.

i recently got up to 24km/sec. God i love E-1000 liquid fuel engines :D

Re: Kerbal Space Program or "Rocket science is harder than it looks"
I'm starting to develop a love/hate relationship with struts. On the one hand, they feel like cheating - They remove any need for finesse or balance, and can make pretty much any rocket work no matter how haphazardly it is put together. They've basically taken the challenge out of building a rocket that works well. But... on the other hand, they let me build monsters :D

Case in point, this little baby:



Using only solid rocket boosters, this improbable stack will reach Kerbin's escape velocity, and with a safe margin at that. Start is a bit slow as in the end I couldn't be arsed to build entire new stages to keep pushing it higher, so I just pasted one I'd already made and added some SAS modules to make the first two. Still has enough thrust to get going, though, and one it gets to the upper stages it really takes off.

And of course, struts also allowed me to finally reach Earth's escape velocity... and then some. Behold, the Big Bertha mk3:



So big, I had to build it off-center in the VAB and build a notch into the lower stages to allow it to ascend past the crane-like protrusion on top of the launch tower, this testament to the utter overpoweredness of struts will casually reach Earth's escape velocity and then keep going to no less than 14.600m/s. It lags so badly for the entire flight that steering is more a matter of luck than skill, giving me barely .5 fps during the initial launch. Even so, steering is somewhat possible... you just need to start any correction 4-5 seconds before you'd normally do it to give the game time to register that you're trying to do something :p

And here she is after all stages are spent - Notice that parts of the interface are still bugging out due to lag:



Dunno what got into Bill and Bob, there. They're probably just glad that horrifying ride finally calmed down some.

Re: Kerbal Space Program or "Rocket science is harder than it looks"
It took some finessing, that's for sure. Had to distribute its weight over 24 'legs' to avoid spontaneous collapse on the launch pad. There's a reason it's the mk3... previous iterations went kaboom :p

Oh, by the way, getting it off the ground takes some work too. The initial launch stage is, I believe, 57 LF engines and 18 SRBs.

Re: Kerbal Space Program or "Rocket science is harder than it looks"
Here's my own Satellite-Lofter. It's a 3-stage design, often achieving orbit with the first two stages alone, depending on payload weight and whether you add legs to later make landing smoother. The craft is designed for powered landings, BTW as leaving a NERVA engine in orbit would get the Green-kerbs panties in quite a twist.

Stage 1 has a 3 meter diameter and uses 7-kerosine engines, and 6 stabilizing liquid fuel thrusters. This one's a beast and takes some skill to fly, since if it tilts over more than a couple of degrees you'll never right it. As you go higher it's recommended to throttle the engine back down to reduce both air drag.



Separating stage 1.



Stage 2 has a 2 meter diameter and uses a single, massive engine. Until about 30 km high, I keep throttling the engine back.



....at 30 km, I increase the angle to about 45 degrees, starting to pick up lateral speed. I also increase engine output as gravity drag decreases, and it makes sense to burn fuel now when the Oberth effect is stronger.



....at around 45 km, we complete the turn to lateral thrusting and give the engine all it's got to take advantage of the Oberth effect.



Separating stage 2 and jettisoning the protective cone over the cargo. Since the cone's decoupler is somewhat anemic it's necessary to do a short side-ways burst.



Stage 3 is a NERVA engine with a massive, 1.75 meter fuel tank.



Orbital speed achieved, releasing payload. Note that I still have loads of fuel left, so I could loft this thing into a lot higher orbit, as is, it's on a highly ecliptic orbit.



Commencing retro-burn to re-enter atmosphere. I waste a lot of fuel, as this could be done a lot more efficiently by burning at periapsis and aero-braking.



Deploying chutes when air-speed has dropped below 300 m/s



Safety burn, slowing the craft below 80 m/s, so the chutes are not ripped off when they fully deploy.



At 500 meters altitude, the chutes automatically expand to their full size



Maintaining 9-10 m/s descent rate until the last 100 meters of altitude, when I increase throttle and land gently at 3-4 m/s.



Safely landed - on WATER! Expect a wet splash in later versions!

So apparently landing on the dark side of Kerbin is always fatal.

That should be fixed in the next Alpha release. HarvesteR said it was fixed. :) I'm looking forward to 0.10-X1.

Here's a video showing off the C-7 Aviation mod and what I've been mostly doing in KSP recently. Orbital flight is so boring... what would be a real achievement is flying around Kerbin in an aircraft.

Re: Kerbal Space Program or "Rocket science is harder than it looks"
OK, am i the only one who thinks those giants are atrocities? xD Here are my puppies:
http://nohiki.ic.cz/gallery/ksp/


Vanilla series -
Spear - Two stage to orbit, pure liquid powered rocket
Maxim - Solid boosted 150% fuel spear
Neo series -
Spear - Improved design for better maneuverability and higher orbits
Maxim - Solid boosted 150% fuel spear with vertical launch top speed slightly over 6500 m/s after escaping gravity (NERVA engine rocks)
Astral - Maxim with heavily overhauled top. Added one stage of fuel efficient mid thrust engine. Capable of launching the full lunar lander on orbit or to infinity without the use of landers own thruster.
Xtreme series -
Improved Neo series with doubled bottom stages. The maxim is there just for fun as it is too heavy and less efficient than N - 2, and the X - 3 never flown :(
Huge series -
My research into liquid booster technology :P The H - 2 will fall apart before bottom stage separation if you go full throttle xD and the H - 3 is my attempt on emergency landing capable rocket / recoverable boosters with parashutes

And how the people build the planes, let alone fly them is beyond me. Even with the .10, i can't build a working shuttle. Any hints?

Re: Kerbal Space Program or "Rocket science is harder than it looks"
That aviation pack is quite interesting, but... problematic. My only successful construction experiences unexplainable roll when using wings (I wonder if symmetry tool flips one of the wings upside-down. It would explain Kerbalish stability, at least if there's difference in lift  between normal and flipped lifting surfaces). A tool showing forces exterted on the spacescrap craft would help with that problem and creating pitch-neutral planes, but I don't think its creation is considered right now.
