APOLLO (SATURN-V with F1 & J2, APOLLO CSM, LEM, LLRV). by OLDD (v.1.4. 09.05.14)

[DennyTX]

here it are

F1 and J2 engines. Scaled 0.55

but some folks said me that here we have an indigame, not a simulator, and engines are overdetailed a lot.

definately.. models are 5-10 times heavy than SQUADS, and 3 times heavy than FASA J2.

and i'm do not sure it will be usefull

[Virtualgenius]

Its cool we all have our moments, that's what makes us human we are not perfect. The models are awesome and if we ever get a 64bit client where we can use more than this crap 32bit memory limit it wont be an issue 64bit client should be a priority but that's an argument for another time and thread.

There is a fine line between kerbalism and realism. Even still, awesome work.

overal weight of both engines with MBM textures is about 10MB.

They are useful by being awesomely beautiful accurate models

[Camacha]

They are really pretty. The more I see these realistic type models, the more I realise I like them a lot more than the old stock ones. I think some parts in KSP needs an art pass, as the VAB and other buildings do look nice enough.

Do not forget that KSP started out rather cartoonish, but that the community has displayed a strong preference for fairly accurate models - be it physics wise or asset wise.

[lnchenxiyan]

any craft file ?

I like the foily look of the LEM

[Reddragon]

The descent stage tank's center of mass isn't aligned with the thrust vector and the LEM starts to spin. Did I do something wrong or it's something to be fixed?

this happens in atmosphere, right? because vessel is highly unsimmetrical

but it should work ok in open space.

tell me more about situation and i'll check asap.

[Reddragon]

This happens in space for some reason. I can see in the VAB that the CoM is not lined up with the thrust vector. I'll take some pictures or even make a video later.

So here they are-

RCS build also confirms the rotation:

Ok, so I observed the problem and the issue is that with the mobility enhancer, staircase leg ALSEP etc. set on the LEM the whole thing get's unbalanced. I had to place another staircase leg and an ALSEP box with an ALSEP module on the backside of the descent stage, so it wasn't so front heavy. I could make it work but it could be a serious problem late if you add the LRV.

Its the landing gear, the ladder gears center of mass is different than that of the regular one. It throws off the balance of the craft. Have them both be laddered landing legs on each side and it will even it out..

Denny, might I suggest having a half-length version of the Apollo Service Module fuel tank as well as the full-length one that you showed off more than a month ago? On the Apollo missions that went to the Moon, they had a full tank because they had to all those fuel-costly maneuvers around the Moon. But the Apollo CSM's launched on Earth orbital missions such Apollo 7 or the Skylab missions didn't require that much fuel, so those CSM's carried much less fuel. It's not inconceivable that if the Apollo program had continued on, NASA would've constructed a special version of the Apollo CSM for Earth orbital missions that would've done away with the large half-fueled fuel tank and instead had a smaller fuel tank that would be fully fueled. It also wouldn't have needed such a big engine, so they could've gone with a smaller one like the Apollo Lunar Descent Engine (which you've already created). Something like this:

So if it'd wouldn't be too much extra work, it'd be great if there'd be a fuel tank that was only half as tall as the normal CSM fuel tank. It would certainly increase the variety of designs that we could make.

I thought that they used the extra space in the SM for the storage of experiments, extra life support needed for the longer 60-day missions on Skylab, and fuel and RCS needed for docking and rendezvous. But I do agree that the engine was a bit OP for crew transfer to LEO.

[hieywiey]

Also a thermal soak heat shield, instead if the aluminum honeycomb ablative would probably save some weight along with batteries instead of a fuel cell (just for SL missions), lighter navigational computers, and an optimized high-gain antenna array.

Since they had all the Block IIs built, they made sure to fill up everything with extra stuff to get the most out of their remaining CSMs. But if you have a permanent space station presence, it makes sense to reduce everything to the bare minimum needed for the job.

[LawnDartLeo]

Since moving on to the latest KSOS, I have had issues with RPM and the LM. SOme message about the config being screwey.

Fix available or in the works?

yup, you right.

i have checked all meshs in 3D max, all were ok with pivots and centers...

and unbalance occurs because of modularity of LEM.

hmm... my Saturn-V and Apollo spacecraft are high modularity too.... Complete Saturn-V-Apollo-LEM complex consists from about 100 parts. And requires KerbalJointReinforement for work, otherwise becomes dancing.

seems like not a good idea to have so high modularity?

[frizzank]

Its where your parts are in unity when you export that matter and not in max.

If you change the cfg so the attach node is at 0,0,0 that is your center of mass. If your legs have the same attach node values then they will have the same center of mass.

If you want two different parts to be perfectly balanced they have to have the same, weight, drag and center of mass.

Some New Items are up.

Also CSM_LEM resources has been completely rebalanced and becomes a bit easy to use.

Wow, amazing stuff! Can't wait to mess around with that.

And I'd love you to make the LM model who flown in Apollo 8. Look at this pic: http://www.astronautix.com/graphics/0/10074959.jpg

And I don't think it will make you lose a lot of time.

[Guest]

Wow. Just wow. This is incredible. How are they scaled? If they're scaled precisely to 64%, you'll be my hero. Also, are you planning to make an APS and ullage motors for that S-IVB?

Here's some info on the former:

http://www.spaceaholic.com/csimages/cssaturn_aps_diagram.gif

And the latter:

http://up-ship.com/blog/?p=17909

S-II retro and ullage motors. Also good stuff:

http://up-ship.com/blog/?p=18233

The S-IVB/S-II interstage had built in retrorockets. I'd propose that you fuse them with the decoupler, with an "automatic fairing" for the nozzle coverings, linked to the bottom node.

Also, on the CM RCS, the red pieces are probably protective covers removed before flight. I've never seen them on the flight-configured CSM.

Looks beautiful. Can't wait to get my hands on it. This together with Frizzank's Saturn V will be great!

*Picks jaw up from keyboard and tries to continue working...*

*EDIT*

No couldn't do it. Had to come back for second look!

*RE EDIT*

I'm going to do the rest of the Apollo programme suits ASAP!

Need. Glorious. Parts...
