Difficult? No, if you know the mixture ratios. Something that BDB itself would do.... Likely also no (I am not Cobaltwolf or JSO just repeating what the answer was to my request for Aerozine-50/NTO for Titan.) If you go to: https://github.com/CobaltWolf/Bluedog-Design-Bureau/issues/552 Jso and I along with a few others discussed how to create patches to the BDB fuel switcher. Please do not post a request for someone else to do this for you. You can see exactly what my personal configuration has modified and HOW I did it in the posts there. Using this functionality I added LF/HTP to the Commonwealth Rocket engines that needed it (Gamma family), I have also added Hypergolic to the proper CRE rockets as well. Besides, Why wouldn't you use the cleanest burning fuel if you are going to go all "Environmental?" Hydrolox FTW!

Just please NOT required Engine Ignitor!

I don't know of anyone who has done a MOD for that. Nor do I know what you would change. In my play-throughs, unless I add DMagic Orbital Science before I break the 45 Science barrier, I am actually mass Limited not part count limited. IF I add Orbital Science part count goes out the window Err, What about a Boat-Tail Mesh switch as well? That way we can run the RS-27A on a First Generation Thor! Sure now we are at 2 parts but 2 parts is better than 5 err, After I get Pioneer up, My payloads are in the 10 to 15 part range. Since I am mass limited by the Launch pad I can't loft BIG payloads. But I can launch payloads with lots of Parts. That being said... See point 2 above Does this mean when Delta K gets redone it's interstage will be used for HOSS in addition to the Straight 8s Delta-F/P?

While I freely admit I am going on scant information. I have this one in the bag. A Titanium or similar coating (depending on the source) was anodized onto the AJ10 further reduce corrosion issues (even Stainless steel can rust in the right conditions.)

UGH! I feel the pain If I recall correctly, the AJ-10s that Delta used did not have a welded "Spagetti" tube structure... They were monolithic solid Nozzles. Remember that Delta's AJ-10 evolved into Transtage, SPS and OMS... All of those are solid wall (not tube walled) nozzles. I will dig into my documentation and verify over the next couple of days. Basically as I understand it, it would just be a texture swap if you wanted to make a "pure" Delta variant (ANY and all of the -118s are Delta!) .... So I hit up Astronautics and wonder's of wonders, pages have been deleted, moved or worse, blanket copied over again... This time on the subject of AJ10.... here is what I can crash together in just a few minutes beteween Wikipedia, Astronautix, spacelaunchreport and DesignationSystems.net: There were 3 and a half DISTINCT AJ10 families... AJ10 Stainless-Steel Tube welded, AJ10 Stainless Steel SOLID Nozzle (never flown) and AJ10 Aluminum tube welded Chamber... Oh and AJ10 Stainless-Steel with a Columbium/Niobium Nozzle. All the Able, Ablestars, and Deltas prior to Delta-F flew with the Aluminium tube welded Engine. Delta-F is essentially 1/2 of a Transtage Propulsive unit and is a Stainless steel combustion chamber with a Columbium Nozzle (US Space companies still call it Columbium even though the SI has renamed the material Niobium) Delta-K has the same basic features of the Delta-F except a bigger expansion ratio (100:1? not certain on the expansion ratio) Obviously both Shuttle OMS and Apollo SPS were Stainless-Steel + Columbium. If someone has more/better info I would greatly apreciate an update to this. As Cobaltwolf has stated AJ10s are hard to get hard data on (pardon the pun)

Cool I guessed right! I assume that we will get interchangeable Auto-shrouds thanks to your Efforts and B9PS? Correct me if I am wrong but wouldn't Thin-Delta (Delta A to Delta D or E) and FAT delta (Delta F to Delta P) not be the same bell shapes but with solid vs brazed tube nozzle? Are the Radiators USEABLE? I also can't wait for the Tracking antenna!

Um. No J93-GE-3s? Wheres the Sooty beef? There are at-least 6 of them sitting around at Wright Patterson... Oh wait... no you can't have them they belong in my next truck! err my Avatar!

well excepting for the whole Benjee10 uses ARR for all his mods..... and why would we need THAT ugly ducklin? LDC can fulfill all it's rolls NOW and is more modular and cooler (cause it is LDC!)

Yay Titan LDC is getting more texture love! Love the Brown/Grey pattern. Err... you mean the original LDC texture? ERr... Are you sure the rocket part's aren't scaled down to 2.5m? I Kid because you could do EITHER and it would look good. Mudwig, I don't disagree with you in anything. The problem here is that NASA developed the DELTA upper stage and ordered the entire rocket as Delta. As far as NASA is concerned the last THOR Delta was Thor Delta M. By every document I have on Delta (which is FEW because up until a few years ago it was my least favorite family, as soon as we get into ELT/EELT/EXELT Thor, NASA just ordered the all up rocket as Delta I or Delta II or Delta III. The USAF ordered what would be called Delta IV but the name USAF ordered it under was EELV and NOT Delta IV. The name Delta IV was to hide the rocket's true lineage because, as Cobalt has pointed out previously I believe, if you want to be true to lineage the Delta IV should be TITAN V! Titan is still my #1 family followed closely by SATURN-II INT-18 (no booing or hissing please! I can like my choices and you can like yours!) And lastly. If you want to get REAL critical. The Delta was an Able with a new GCU and a different variant of the AJ10... Then it was an AbleStar with a new GCU....and a similar variant of AJ10 as the Able derived Delta... So why didn't we call it Able or Ablestar?

First off I want to say YES I can come off sounding like a Fanboy but I don't care. @CobaltWolf I absolutely love what is going on with BDB at the moment. Delta III. The LAST of the Deltas is flying completely out of BDB parts now. Thanks to @blowfish for making the part, and B9PartSwitch, and the advanced Tweak-able features there within! Thanks to you for the texturing and quick inter-stage work. I am blown away. Now Delta will last a LOT LONGER as my preferred LKO Satellite launcher. Cobalt, I do have a question, you are talking about re-making and accuratazing much of the early rockets from BDB. Is there a plan or thought given to Diamante? While it is not my favorite Rocket and it is not a US Rocket.... I find myself using parts from it more and more lately as I start my new career. Admittedly this might just be due to node placement in the Tech tree ...

Ohhh! SO Agree with the potential. I didn't want to comment on the part originally because I know you "love" for Delta IV Cobalt, That being Said I like the texture and Blowfish did an amazing job with the actual part. The best part of the texture is the fact that on one side is Stringers and on the other side is a Waffle pattern (top support ring above the LH2 tank.) And the orange insulation foam literally looks like someone sprayed a 5% overlap (just like real life) I can see a lot of uses for this. The Biggest being JUST to make Delta II/III parts relevant longer in my play-through but as an LDC 3rd stage.... Potential! It is too bad there isn't a way to alter boiloff rates by tank in the BDB boiloff plugin (or if there is that they are not being used!)

Well... It was pretty... Till that white fangledly bit was hung off the right side... Oh wait! it has Jet engines. Never mind. That is a good space shuttle!

Nice Chart. Yeah I went overboard a bit on the MLVs... But there are several Stages that are "Orphans" as well that did not make it into the final MLV document (where those various MLV model numbers come from like MLV-V-1) And yes structural strength DOES impact the game... If the original parts are set to what they should be..... I built the MS-IVB parts on a whim and will probably not upload them. The MS-IVB Stretch is just the S-IVC length and fuel wise so if I ignore the Strength differences no new parts.

VERY VERY NICE. I am about to update the Pafftek folder with a total of three MS-II stages as well as I have made the MS-IVB tankage... The Key to the MS-IVB is increased strength. IDK if it is worth including but I am currently testing it. RE disparity on MS-II tanks that was mentioned previously. I scaled the mass up by the Real World Percentage. I forgot Cube Root rules. They will NOT be a huge gain in Delta-V but the tanks WILL provide more than would otherwise be had now. I assume NFLV is Near Future Launch Vehicles?

Actually that is more of an urban legend than a fact. The Statement is/was based on an administrative decree + using the wrong data (Saturn I vs Saturn IB) I did some math on that with one of my College profs (who was an engineer for Apollo blk2 at Rockwell NAA division) A First run Saturn S-IB CAN lift a full C/SM...... HOWEVER since it would not get above LEO, there was ZERO point to all that fuel. It was an administrative DECREE by NASA that stated it couldn't carry a full fuel load (and rightfully so!) The Extra capacity was used for things like the Apollo Soyuz Test Project Docking port.... The Saturn I decidedly CAN NOT Lift a Full S-IVB + full C/SM That is because the first stage tank is significantly heavier than the S-IB (and has lower powered engines!) In game, I never fly a Blk2 in LKO with more than 50% max fuel.... Intentionally

This is true. You do not launch a Saturn (any) with a Quick Gravity turn. Rather you throw it straight up(ish) and then bend it over (hence my two launches with a Different Curve... I made orbit with the second Curve but it was still not right.) I seem to remember that BITD JSO tried to do this same engine thrust nerf and had the same problems..... IDK. I could be miss-remembering because it was about the point I started following this thread that that happened (what 3 years ago now?)

BDB-Extras/Pafftek Folders. There is the INT-11 Tankage for the Saturn I INT-11 (4 UA1207s 4 H-1s and a 20ft tank stretch over Saturn IB's first stage) Many MLV Saturn V parts (via rescaling the BDB tanks) and a Drop in for the HG-3... And for you Atlas SLV-3X or BIG Atlas-F fans the H-2 Engine

TEsting Goal is a stable nearly circular orbit at 300km with a Saturn IB with the 1973 Ed H-1 rocket engines. Only non Stock to BDB items is my SM uses AZ50/NTO instead of LFO. Launch 1 Stock Saturn IB with AZ50/NTO for SM fuel (at 50% to match real world settings ) No payload in the cargo bay (again to match real world) 1973 edition H-1 engines. Failed to orbit. Delta V is 5683m/s and I did a 40% Launch slope via Mechjeb. 40% is what I use to launch Titans with Solids... Launch 2 (as above) 80% Launch curve (about as square of a turn as I want to get with a big rocket) FAiled when Saturn SLA overheated and blew up. Capsule and SM actually survived and via a Dive into the Atmo was able to make orbit but still an orbit FAILURE due to overheat and blown parts. Max altitude was 86km when on the S-IVB stage Reached that with 2 minutes of fuel left in the S-IVB stage. While the C/SM did make it to orbit... I consider launch 2 a failure because while the S-IVB stage reached 86km it then fell back down below 60km and burnt up.... only Luck and my quick reactions saved the C/SM and allowed it to make orbit.

Before you go changing thrust on the J-2.... Try making a Saturn INT-05 and a Saturn INT-05A. S-IVB and above is the same but below the decoupler is the Short and then the LONG AJ260. Confirm if you have orbiting problems with either of them. I know that Ohiobob and Galileo have put a lot of effort into the new "Solar system" And I don't know what if anything they might have done that could cause a rocket nerf. I will do some testing in a bit (I need to test my updated MLV parts as discussed a few posts up anyways!)

While I agree with @Dragon01's concern about clutter in the RightClick menus. I do Agree that this is more sensible than not, and this does not even come close to saturating the Right Click menu like other mods do already. While I would prefer Historical Parts and AB-Historical parts to be separate.... The LR87 family is so muddy and many unflown but built variants etc.... So here is my proposal. Part count increases but I think this is a little more "Logical" to my thinking I am probably setting you up for more work but I suggest any AB-History part get an alternative texture that is obviously not standard in Coloration? It would give a Quick visual clue to those who do not know their parts all that well... LR87 Single Bell (they never flew but MANY MANY were made!) 3 parts 13 total variants Hypergolic AJ-5/9/11/11A/11V (5 variants) Hydrolox SL/V (2 Variants) Kerolox AJ-3/5/9/11/11A/11V (6 Variants) Slight Higher performance but much higher cost on AJ-5 and latter for part balancing purposes... LR87 Twin Bell (As above many made but not all flew) 2 or 3 Parts and 9 to 13 variants! Hypergolic AJ-5/9/11/11A/11V (5 Variants... 11V currently has no model but I think it can be kitbashed from Single 11V part above???) Hydrolox (PLEASE PLEASE???? Sea Level and Vacuum optimized for 2 variants!) Kerolox AJ-3/5/9/11/11A/11V (As Hypergolic. 6 Variants) LR91 4 Parts 10 total variants Kerolox Quad Vernier AJ-3/5/11 (3 Variants two being Hypothetical) Hypergolic Quad Vernier AJ-5/11 (2 Variants) Kerolox Single Vernier AJ-3/5/11 (3 Variants 1 Hypothetical) Hypergolic Single Vernier AJ-5/11 (2 Variants) With no model addons/changes we end up with 9 parts, and 32 Variants... Which could grow to 10 parts and 34 variants with two new parts! Little Bit of History on the LR87/LR91

Actually the nodes were fixed on the FB variants a week or so ago. And then Zorg figured out why the H-2 engine was not working and solved that issue a day or so later. The only thing that was not updated in the Pafftek folder then was the S-IB INT-11 tankage and that just had to do with realnames changes that Zorg is implementing

I have not seen that picture before but neat set of rocket models. I may get into measuring scale on them since they seem to be the same scale from one to the next. It is easy to see why Saturn VIII and or Nova-8 failed to be considered.... Too tall and as I recall, the structure of the VAB would have to double or triple in mass to support that slight extra height (which is the actual why for the Flat or Common bulkhead S-IC variant in the first place!) The neat thing is I fully think your S-IVC add on tank is the PERFECT size already The lack of a good looking large nose cone (With Fuel) is the biggest failure.But given that the S-IC thrust structure attachment points are at the TOP of the S-IC or the Bottom.... It would be neat if some day you made a combined Nosecone/Decoupler that has multiple sizes of Nose-cones and the structural web also acted as a fuel conduit....Attach nose cone then attach various rocket parts below for the Strapons... But That is kinda single use and would be cludgy looking... even if it is the correct way for the AJ-260 or Saturn LRB to attach to the S-IC. On the Game play. 10,000+ m/s d/V is nothing to sneeze at! I think on most flights I end up with about 80 units of LF left in the add-on tanks when I separate the AJ-260s due to Solid Fuel Depletion. But that is with a fuel filled nosecone as well. On other sources. The 1967 Boeing MLV study has literally ONE SENTANCE that references this AJ-260 configuration in the paragraphs dealing with the Pros-cons of the full length AJ-260 in regards to the MLV program. Lastly I will do a Pull within the next 36 hours as I need to update the S-I INT tankage as well as some minor tweaks to the MLV file. @Mudwig I will double... actually tripple check the MS-IIA tankage. I may add a second MS-II variant as well. I also want to clean up some issues with the MS-IC family that I may have messed up in my last pull request. @Zorg thanks for catching my mistake on the H-2 Big Navi engine... I am trying to decide if I should revert that back to the old model... or switch to a Rescaled E-1 model. Those Rings on the H-1D engine stick WAY out of the Atlas booster Engine skirt! Now I just need to figure how to get the new realnames system you have implemented to actually work for my parts...

For followup. The Description of the MS-IC stage to support the quad AJ-260s http://www.astronautix.com/s/saturnms-ic260.html and one of the many full up configurations (this is what I consider the BASIC configuration. http://www.astronautix.com/s/saturnv4-260.html A more "Fun" version using the S-ID first stage so 0+ Stage and A Half For First stage grouping... http://www.astronautix.com/s/saturnv-d.html Starting at the Top. The Core stack Saturn IU (aka the Guidance and Control Unit or GCU) Saturn S-IVB tank Saturn S-IVC tank Saturn S-IVB Engine mount + 4x Saturn APS RCS systems + 4 Saturn S-IV speration motors J-2T-400K (extras folder) S-II to S-IVB interstage MS-IIA-1 tank 5x S-II Engine plate with 5x J-2T-250K Engines (BDB S-II to S-I Interstage with 4x S-II Seperation motors attached TO THE INTERSTAGE <- this is the correct location for those! 5.625m Stack Decoupler MS-IC-25 Extended lenght tank S-IC engine mount with 5x F-1 Engines (no F-1As here) The AJ-260s are the FULL length versions with the following parts (most are Stock and from the Stock Expansions.... Need a 3.125 or 3.75m Conical nose TANK for BDB at some juncture (Tweakscale can make it better but the little nose cones in Stock or BDB look weird when scaled up. I have the following parts for the AJ-260 Asparagus: Stock FLA-150 Tweakscaled to 1.875 Stock FLA-151S Tweakscaled to 2.85m Stock FLA-215 Tweakscaled to 3.75 BDB S-IVC Tank Fuel Conduit run to MS-IC-25 tank AJ-260X Radial SRB. Obviously all the fuel tanks on the AJ-260s are set to Liquid Fuel + Oxidizer and not Hydrolox.

I am building it in Sandbox as soon as I can get KSP up and running Thought I would share a photo or 2. IRL the only references I have that spell it out clearly is the "Wonderfully self contradicting" Astronautix.... Beyond that I see mention of the Quad AJ-260s needing a lengthening so they can match up the MS-IC's Thrust structure. This to NOT have to make an entirely new S-IC alternative tankage + Engine plate... aka a completely new first stage. I will post the in game shot after I go take care of a Wasp nest (stupid wasps got in my house through the FRAME of a window today!)

Friznit, One thing I noticed on the MLV page. No Saturn V(S)4 with the AJ-260s and Aux Fuel ("drop?") tanks for the MS-1C. Build the Tallest MLV Saturn V (MS-1C maximum Stretch, MS-IIA, S-IVC [Sure it is from ETS but it fits... ish!] and Put 4x of the long AJ-260s in line with the F-1s on the MS-1C. Then take 4 of the Auxiliary S-IVC tanks and put them on top of the AJ-260s. Pass fuel line to MS-1C tank. Put nosecone on AJ-260s. Ignite all the AJ-260s and F-1s (no F-1As on this rocket!) on launch pad. The Aux Tanks will JUST ABOUT be empty when you jettison the AJ-260 and their attendant aux fuel tank.) TBC the Aux Tanks on top of the AJ-260s must be the first to have fuel drawn from and they are full of LF/O not Hydrolox... so have to flip the switch as default is Hydrolox. I can carry a Full Apollo lander stack to Jool with this If I time my launch correctly Durn limited functionality to the boil-off feature! I am not getting Identical Delta V numbers but they are similar enough for me to declare that the difference is rounding errors... Scan your install with Steam? IDK what to say
