Eyes Turned Skywards

Just finished the entire TL so far, excellent work!

I do like how the Apollo was designed for lunar flights, was converted into a space taxi, and then converted back for Artemis :p
 
FYI everyone, after some discussions over the licensing to use, we've agreed to make the 3D models available under a Creative Commons BY-NC-SA license - so you can use them how you like, as long as you give credit, don't use them commercially, and share any derived works under the same conditions.

Anyway, now that's sorted, I've created a page on the wiki where I will post links to the 3D models. I'll add more as time goes by.

Have fun!
 
i want to make my Picture for ETS also available under a Creative Commons BY-NC-SA license.
my problem is how to replace the old picture with new on AH Wiki.

next to that i have my hands full with 2001: a Space-Time Odyssey
 
Ack! I'd been working on an official announcement, but I've been scooped! :eek: :D Anyway, as you can see above, the timeline as a whole is now being clarified as being under a Creative Commons BY-NC-SA license. Basically....you can use stuff from the TL (which, thanks to the generosity of Nixonhead and Michel also includes their art), except for commercial purposes, as long as you credit the creators and allow whatever you make to be used under the same criteria. Just for the record, we're basically okay with "attribution" to Eyes itself being either a link to the thread or the wiki. I'll let Nixonshead and Michel say what they'd be okay with as far as attribution for their art.

Brainbin's guest posts are also being released on a Creative Commons BY-NC-SA license, though with the specific caveat that since we talk a lot advising each other on our respective TLs, there may be some crossover of material from his TL to the guest posts. He'd like to keep those his own. While we don't have a specific example, we wanted to mention it in case it comes up.

Anyway, beyond this, behind the scenes work has been pushing away on Part IV, and we're really looking forward to all the cool stuff we'll be bringing to you when it's ready!
 
This is so cool! I'm also really excited with the Kerbal Space Program mod y'all are making!

I PM'ed Nixonshead about this but I thought I'd post the TL's artwork to a facebook discussion group I'm part of called Space Hipsters with credit to the TL authors, Nixonshead, and a link to the timeline. I think people would really get a kick out of it! I assume under the new licence that would be okay?

Yes, that should be okay. BY-NC-SA means that you can share and modify our work so long as you give credit (as e of pi says, by linking this thread, although since you want to post artwork specifically, you need to talk to Nixonshead and Michel about what specifically they would like in that regard), don't use it commercially, and license anything you create on the same terms. To quote from the Creative Commons foundation,

Creative Commons CC BY-NC-SA said:

Sorry for scooping! :eek:

That's all fine by me. Just make sure to keep any banners I've used on the image to credit any 3rd party elements I've included in the images.
 
Have you thought about making add-ons for Orbiter Space Flight Simulator?

As with the Kerbel project, I've no objection to anyone using my models as a starting point for an Orbiter mod (and I suspect e of pi and Workable Goblin feel the same), but I lack the skills or the time to develop a mod myself. If others wish to take up the call though, I do plan to link all the models on the Wiki. eventually. If anyone has a particular model they'd like me to fast-track, let me know!
 
My sincere apologies for dropping the ball on this; right as the project was starting, KSP .24 dropped and I had to scramble to update my mods. I also finally am employed (woo) so that takes a good chunk of time as well.

The post on the KSP forums has been updated to now include a link to a worksheet I have created for all assets to be listed and people to sign up.

I also have some questions I ran into while drawing up the list (which is still a WIP--Eyes is such a rich universe, there's so much stuff!).
*If a piece of equipment shares the same name as OTL, is it the same? E.g. Castor 120

*How does the J-2A-2 achieve its stated Isp? Staged combustion? Can't be expander because that has a hard limit on thrust, or at least so I understand...


*Is the CCM46 the GEM46?

*Is the engine of the Delta 4000 the RS-27A? If so, why is the Isp lower?

*What engine do the new Apollos use? I *think* it was mentioned it was the LMAE, but I'm not sure.

Roughly speaking, yes.

*How does the J-2A-2 achieve its stated Isp? Staged combustion? Can't be expander because that has a hard limit on thrust, or at least so I understand...
The J-2S is a tap-off cycle, a variant on the gas generator cycle of the original J-2. Instead of having a separate gas generator combustion chamber, it taps combustion gasses off the main chamber. This allows the higher pressures of a GG engine with a mechanically simpler engine.

*Is the CCM46 the GEM46?
To within margin of detail, yes. I directly stole GEM-46 specs when creating it.

*Is the engine of the Delta 4000 the RS-27A? If so, why is the Isp lower?
The 1970s-origin Delta 4000 uses the original RS-27, not the improved RS-27A. The Delta 5000 was supposed to use the RS-27A, but looking at the wiki it seems I didn't get that incorporated into its stats. I'll need to update that at some point.

*What engine do the new Apollos use? I *think* it was mentioned it was the LMAE, but I'm not sure.
LMAE, IIRC.
 
Great, thanks!

On the J-2, I guess I was just surprised to see RL-10A3-level performance from something that wasn't expander or closed cycle.

On the CCM46: I ask because KW Rocketry has a decent GEM60, IIRC, that we might tweak.

Speaking of solids: are the Europa 2-TA solids based off anything real? (ferram's making the Europas out of procedural parts and we wondered about the solids' stats.) And on the Europa note, he points out:
ferram4 said:
The Europa 44u (and likely the 42u) lack the ability to liftoff without lighting the core; however, lighting the entire core results in the boosters burning out at the same time as the core, since they use the same engines and have the same fuel load relative to thrust. Which means the core needs to light half its engines. Assuming no uprating of the RZ2 for more thrust (not a good idea) or adding throttling (probably a little too advanced, I think). And I mean, down to 60% or so throttling.
On the other hand, the 1 and 2 haul.
 
Great, thanks!

The tapoff cycle is a variant of gas generator, and not an uncommon one even for hydrolox engines--others include the original LE-5, the European HM-7B and Vulcain. It lets you get pretty darn close to the efficiency of an expander cycle, while having higher thrust. Staged combustion is a bit better yet, and really shines in SSME/LE-7 applications where an engine is firing for a substantial portion of a flight to orbit. There, you often see ISp (vac) of around 450 only because the nozzle must be seal-level optimized for liftoff thrust, otherwise they'd do better yet.

Seems workable. As I said, they're identical to the limit of detail--I won't say that the welds or whatever are all the same, but I used the OTL GEM 46 as the specs base for the CCM 46 and they have the same rough dimensions and properties.

Speaking of solids: are the Europa 2-TA solids based off anything real? (ferram's making the Europas out of procedural parts and we wondered about the solids' stats.)
They're based off a French solid of OTL--I can't recall the name offhand, and forgot to add it to the wiki. I'd need to dig through my PMs, or Michel Van can add it if he sees this--it was his suggestion.

As far as the heavier Europas...I'll just say that while the RZ.2 hasn't received a full makeover ITTL (largely because figuring out upgrade paths for engines is a pain), it has seen some facelifts. One is the capacity to throttle, which is enough to let the core burn a bit longer than the boosters and control max Gs. Throttle's not that tough an addition by the time Griffin is developed--they added throttle to F-1 and Merlin after the fact, and like those RZ.2 is a fairly mechanically simple gas-gen kerolox engine.
 
Great, thanks!

the P16 aka "Black Diamant" is base on real hardware, the P16/902 - first stage of the French MRBM "Missile S2"

Thanks, Michel. I always get confused because it's unrelated to the Diamant rocket itself. Astronautix stats.

It's confusing because the P16 was proposed for Advanced Diamant
Like Diamant P16, super Diamant, hyper Diamant
In end CNES refused those ideas, mostly Not becomming depending of Military Program with top priorty on MRBM.
So CNES take the Diamant B Design.
 
e of pi: Huh, interesting on the tap-off cycle. Off-topic, but do you know if HG-3 was still tap-off but with a high chamber pressure, or closed cycle?
Ok, I'll pass that on to ferram regarding the RZ.2.

Michel Van: thanks! I did actually look up Black Diamant but couldn't find anything on astronautix. Didn't realize it'd be under its military designation.

Oh, one other thing ferram and I were up to that slowed this down: this. Not sure whether it should go in Post-1900 or Images and Graphics though...it's sort of half and half.
