That's the spirit!

God no it will probably break so much... But that's partially why I do such long dev cycles. I'm aiming for a release at the end of the month.

Yes, the Titan engines were redone from scratch and use different names to reduce save breakage. Similarly the engine ramping - if I remember that was mostly just to give a delay for the startup audio fx to play (the Titan bwoooop) We are in the home stretch working towards a release so it should be relatively stable if you want to help test.

But the engine ignitor patch is so fun tho

Engones generally have to ramp IRL dont Thu? If so deal with it if I had my way the BDB engines would have realistic throttling too

So this would already separate the boat tails from the engines. I'm saying one part maybe with original Thor boattail, universal boat tail (the upgraded one for 9 castors, though I think all that detail might be in the decouplers...), Delta II boattail. And then maybe the Juno one in there? And then I'm saying the LR-79, S-3D, RS-27 and RS-27A all in one part with B9 switches. The verniers would be separate too. Advantage of this is you can use like LR-87s hopefully in the Thor boat tails. Hopefully. I think theres probably going to be a 1.5m interstage with a bunch of variants. Redone Delta II interstage for starters.

Well I'd make the early game probes more granular for the same reason.

I've been thinking... So the far better option IMO is to make LR-79 as an independent part. Possibly with a mesh switch for the different variants... Separate the boattail, engine and verniers... Now the problem is that makes Thor much less viable early game from a part count POV. So... What do people think about that? Personally I like breaking the parts up more to make building rockets more granular and detailed. But is that an issue for people? Personally i dont like the part count restrictions early game. Are people playing with something that modifies it? I know a lot of people like sandbox but personally I always wanted BDB to be a career mod which is why part count remains a concern. If I do that I'd probably put in the work of separating out the RS-27s and LR-101s from the Delta II boattail and make the RS-27s B9 switches on the LR-79 base part. I'm already more or less committed to redoing the Delta K upper stage.

Still aiming for the end of the month for release of BDB v1.6. I'm traveling this weekend and won't be able to get progress on the handful of remaining things. But, in the meantime... oh god I can't wait to start pushing stuff for the next update... (before y'all get upset, this is stuff I've been working on when I'm stuck on my non-Unity PC) Redone GE-405 Vanguard enginer Thor/Delta revamp already has a good chunk of progress done... Ablestar and Delta E Better look at the (still untextured) underside - note the more accurate internal layout. Don't really know what I wanted to show with this image... just a closer look I suppose. Also, we decided to make the Able, Ablestar/Delta and Agena use interstages this time around. The reason should become apparent as we move forward... Er, well actually if you look at the image above at least part of it should become apparent - the AJ10 needed to be recessed into the stage body! We're FINALLY getting some proper Castor 1s and 2s... and oh, what's this? A new, accurate, and super unique radial decoupler? wow! Mockup of the proposed HOSS upper stage - basically, cut down Thor tankage with an RL-10 on the bottom.

That's awesome! Welcome to the forum! That's so cool! Good to know that 1.875m adapter interstage works nice!

Maybe if/when we do a Mercury revamp. There's also the MA-10 retro pack which might be worth doing just for shiggles. Basically a the same retro pack but with extra consumables mounted to allow Mercury to fly a 3 day mission. Considering the amount of failures on the flown "long duration" missions, I am somewhat dubious that the pilot would have been able to make it home at the end of the 3 days...

Yeah I was just trying to figure out something a little different. I'm still not sure about the contrast but I think this part set might have needed it. I forgot to actually list what I got in game last night: Large surface radiator (switches to conform to 1.875m or 1.5m parts) Small surface radiator (similar switches, I didn't use it in that build but it's basically half as wide but the same height) MOL Tracking Dish (the long dish-on-a-stick on the bottom of the station, no, sorry, it doesn't actually rotate to track anything. Beyond the scope of the mod) A 1.5m switch for the ring docking port (unfortunately the ring itself is >1.5m so you can't put it perfectly inline in a stack, but hey at least it will mate nicely to 1.5m stuff now) A classic! I kept thinking about trying to make it but there's no good way to represent either of the access options. Plus, like, I'm not sure it would have a purpose in game Since the science returns would be so low.

Well, I did trawl through the entirety of the L2 historical section earlier today and yeah, there is a single line drawing that definitely seems to show that the AJ10-118F has more or less the same combustion chamber and nozzle extension as a Transtage engine. Past that there was nothing. I'm fairly certain the "FJ" variant is closer to a 118K than the 118F, but it's hard to tell. The ISPs I can find listed are higher than the 118F but lower than the 118K Interesting thing for those that don't know - the Delta II upper stage tankage design was actually developed for the Japanese N-II rocket. The Delta production line had all-but shut down by then due to Shuttle, and the N-II keeping the production line mostly intact more or less saved the vehicle family.

You can find other sources, but it requires trawling places like NTRS, NasaSpaceFlight, etc. Which, fortunately, I'm willing to do for BDB so if they're out there I'll probably find them. RE: N-I / N-II, that makes a lot more sense, I get where the confusion was now. Considering the AJ10-118K is also described as ITIP in many sources, I agree that the primary difference is the much, much larger columbium extension. I just wish I could find a damn picture, preferably in color, of the AJ10-118F... if it's really just a different extension... well that makes things easier. I can't just "reuse" the Transtage engines (and I'd want to make it higher detailed than the Transtage ones) but at this rate it looks like I'm redoing the rest Delta II upper stage with 1.25m tankage anyways. EDIT: At this rate, it looks like we're going to have: Able-type tankage / Able-type AJ10 (Note there will have to be alternate versions for Vanguard and I think there's differences between Thor-Able and Delta that would make them different in KSP) Ablestar-type tankage / Ablestar-type AJ10 (Ablestar) Stretched Ablestar-type tankage / Ablestar-type AJ10 (Delta E thru Delta N) Stretched Ablestar-type tankage / Transtage-type AJ10 (Delta 0xxx thru Delta 1xxx) Stretched Ablestar-type tankage (with a different aft skirt) / TRW-201 (Delta 2xxx to 3910) SSPS-type tankage / Delta II type AJ10 (3920 to the end of Delta II)

Well, first off, don't use Astronautix. I'm fairly sure the number of pages that I confirmed to be inaccurate outnumber the pages that I know to be right... Second, you might want to get your head checked: LE-3 was domestically designed and produced in Japan. Moreover, why would Rocketdyne be responsible for an AJ10 engine?

Totally understandable, especially because the M that preceded it had numbers referring to the SRB count (Delta M6, etc)

It was the first generation of Delta to have an 8 ft diameter the entire length of the core - 8 ft first stage with an 8 ft fairing on top.

I thought about doing the LE-3 but its performance is so sucky like, why bother... And, I plan on doing Delta proper justice this time around. I just need sources rather than forum speculation. Links, please. This image certainly seems to support the idea of a Straight Eight using a Transtage esque engine

B9 Part Switch

I have that image, but unless you can provide more of a source I don't want to assume anything based on that one image. Most of the images I have show a spaghetti chamber. If we need to just call it a Delta engine we'll do that. These are some of the images I worked off of:

There was a big... discussion yesterday via IM about whether the new stuff should use autoshrouds like they do currently, or try to make interstages for everything. It kinda just stressed me out and made me want to throw up. I don't know what you mean, I am fairly sure these engines are right but trying to find info on the Delta stuff is effing miserable. The radiators would work but... y'know they aren't really needed cus KSP? I just wanted some greebles. I can't actually make the antenna track anything. That's just what it's called in the documentation I have.

Some final MOL/GMSS stuff... Radiators... cus uh... I wanted to greeble... \ Finally, the BIG solar panels for your Gemini space stations! The large fixed array for scale. Deployable tracking dish, excited for this one in particular...

Much more accurate Able and Ablestar AJ-10s. Not for this release, sadly... But I'd hope they get on the Github pretty quickly once that is pushed out.
