Work-in-Progress [WIP] Design Thread

...More Duna delivery preparations: [...]

I want to see that finished base! I do have a feeling you could do with a bit more variety, though, but I know how hard it is to standardize containers and still keep a unique look for each kind of module, all while keeping mass in check so the delivery system can cope with it.

Currently working on a Space Shuttle powered with the new monopropellant engines. Not because it is useful, but because it is cool! It's all stock (except Mechjeb).

It goes into orbit and lands just fine. Well, to be honest, I still haven't managed a landing without breaking the engines, that's only due to my lack of piloting experience. The stock cargo bay is operational but still needs some reworking to make it look better.

Here are some pictures:

That's a challenging build! But keep at it, you'll learn lots. Off the top of my head, I would tell you you have too much of the job of going to orbit riding on the orbiter with its poor isp engines. I would increase the size of the ET and beef up the main engines on the orbiter to compensate (mine are pairs of a LVT-30+LV-909 clipped together, much more thrust than LVT-45's). At the same time, take a lot of the monopropellant in the orbiter out: you will have less work to do to put it in orbit, and the ET will do a bigger part of it. But of course, that comes from having built my own version, YMMV and you might have another direction for your build. Mine, BTW, already has its modded bay installed, and right now I'm seeing whether or not that leading edge wings do something... my guess is not really, and I can take them out and clean up the bay).

hrm Jupiter232 ... very interesting concept of a Mun mission ...

It looks good, but I doubt you can make do with just LV-T45s on the core... I foresee that size is a job for, at least, skippers, if you just put three engines. But I think you could make them fit... or add a clipped aerospike to each or something.

Rune. Just like the real thing, my shuttle also recovers half of it's √86,000 cost upon returning to the runway: so it saves money while still costing more than the alternatives! :D

you know Rune ... partclipping. actually there are two 30's and 45's on the upper stage and 9! 45's at the corestage clipped together. just experimental right now, still have to design a lander and fairings...

Lazarus. if one LV-T45 is not enough, double or tripple it :cool:

edit: liquid fuel booster .. thats the magic ! muhaha rebuilding corestage

Oh, clipping inside itself, that makes sense. But you could indeed save a lot of fuel routing headaches with the LRB and its twin nozzle (not to mention the stupendous T/W), and using skippers for the upper stage, two would definitely fit in there, reduce part count, simplify fuel routing, and look like bigger vacuum bells. Of course, that would make the nozzles on the first stage look smaller... you know what? I'll leave you to it, and praise when you post the results! :)

Rune. I've always liked the Skipper, yet I never end up using them. Well, except as F-1 equivalent. :P

Thanks for the tips Rune. Actually, I found weird the fact that I needed so much fuel in my orbiter whereas similar designs needed so few. I manage to reach 70+km apoapsis with the fuel from the ET but the orbiter then has a huge task circularizing the orbit.

Trying to follow your advice, I removed most of the monopropellant so I could double the size of the bay! :D There's also a huge gain concerning the weight (lost more than 1/3rd). I'll keep working on it when I have some more time. It looks very promising now!

I'll probably get a warning for this.. but why . can't . we . have . stock . cargo . doors . Same reason as no fairings? 'Just slap it on the top of your rocket or hang it on the outside of your shuttle..'

the new rcs engines are really cool for making stylish things.

stock near future energy core/generator subassemblie

part count at the moment: 36

here you can hopefully see the low backligthing from a hidden headlight to generate a little glow effect

You are welcome! I hope it works for you.

Funny you should say that, have you read this week's dev notes? The intern is working on "the MK parts". If I had to throw in my two cents, I'd say at some point, probably coincident with the new aerodynamic model (that has been talked about since before I bought the game), a big update focused on spaceplanes will rebalance everything and add the bits that we are all waiting for, and a couple we didn't think about but will become totally essential in short order. Like, I don't know, stock robotics or something. Notice I AM totally speaking out of my ass, but it would be consistent with the available info. Spaceplane parts haven't had a change since they were introduced, and back then the aerodynamic model was kind of a hack by C7 before he became dev!

Rune. Until then, most of the concerns with planes are quite well covered by mods (Ferram, B9, Spaceplane Plus...).

I have been working quite a bit on that shuttle, following Rune's advice and (I admit) borrowing some ideas here and there from several great designs on these forums.

It turned out really great, I really like it. The cargo bay is twice as big, the orbiter lighter and the whole thing more stable (thanks to those new verniers engines). Max payload weight is somewhere around 2 tons. Part count is 180ish without payload and can definitely be improved.

Still some fine tuning to do, such as the separation procedures of the boosters, the external tank and the disposable cargo doors that are not so ... reliable, let's say. And the landing is a mess, it ends up most of the time in a pile of debris and the kerbals smiling in the cockpit. I am really considering a parachute landing!

That looks really sweet! It is certainly moving along in the right direction, glad to be of help! And don't ever worry about the "borrowing": if someone doen't want yo to pilfer their design as you want to, to learn how it was done or just because you want to... well, he shouldn't post them here, because that's what this forum is for! :D

Rune. It's why this community rocks, now I have to learn how to build a stock payload bay with doors.

Brace yourself..... Shuttle season is coming

0.24 and Rune :P gave me the motivation to continue my shuttle crafting, so here you go.....

It's a work in progress but has less parts and a .... ton of fuel to spare :D

You should redesign the tail a bit so that it matches the height of the cockpit. Then, maybe a cargo bay door? :wink:

Speaking of Space Shuttles, I have built an updated Odysseus that is compatible with 0.24. I'll be leaving for vacation tomorrow and I won't be able to play KSP until the 15th. I'm planning on building a 2.5m diameter payload bay shuttle then.

We all let it go for a while every now and then. Perhaps 0.25 will bring you back with a vengeance, and enjoy other stuff while you rest from killing green dudes!

Well that didn't last long...ONWARD TO CONTRACTS!

This works as it is now which is even better.

That is a nice, big shuttle! Now where is the old Shuttle thread so we can update it with all of the awesome replicas the new Vernors seems to have sparked?

Rune. To the depths of the forum my braves!

That is amazing! I would have never thought to use two cockpits like that.

Yeah, it really helps with the "hatch obstructed" problem. But the cockpit is still my most hated part of space shuttles....
