Great attempt... You have attempted something that Marshal SFC / ABMA never did. You made a stage up of actual Redstone and Jupiter tanks(ish.) Historically: MSFC/ABMA did NOT take Redstone and Jupiter tanks to make a Saturn. They used the machine tools and jigs that were used to make those previous rockets and made ALL NEW TANKS that had nothing, other than diameter, to do with Redstone and Jupiter. Some materials from the previous stages remained but mostly they were all new tanks. This saved a huge amount of mass as your test flight has just shown. By building it your way you are literally adding ~20% to the weight for useless things like inter tank fittings, separate Fuel and Oxidizer tanks within the big tanks and whatnot yet again proof the media is dumb. "oh they re-used the tools that made both the redstone and the Jupiter. it MUST be actual Redstone and Jupiter tanks making up the Juno-V stage... I will report it as such" Still all said and done, A) Valiant attempt, and B) safe getaway Suggestion before you launch your rockets (this is something I do all the time) go to the action groups and make certain you shut down EVERY engine that is not part of the escape maneuver. This won't stop a run away stage but might have saved the debris or at-least more of the rocket to recover. I mean you can ignore this step if you are doing it for the lols

while a good idea, J-2 is a Rocketdyne engine and RL20 and XLR-129 are both Pratt and Whitney. It is safe to say that the J-2T-400K needs a lot of TLC (I can actually reduce part count by creating a engine switch to add it to the standard J-2T-200/250) The performance would stay the same. But one less part to filter through (I am likely going to be doing the same to the LR87-AJ-11 for the AJ-11A of the Titan IV.) I haven't decided how far down the rabbit hole I want to dive with my adendum patches in the extras folder Just nice to see someone using one of my patches once and a while

INT-17 is a "Paper Rocket" not meant to actually fly. ALSO the program ALWAYS ran it in their simulations at like 75% S-II fuel load and 80% SIVB fuel load You are also using the 7 engine mount yes? also thanks for using my J-2T-400K patch RE removal of the J-2T-400K, That is my flavor text. The one document that covers it does not say where the extra power came from and I *ASSUMED* that it was from a HG-3 Turbo pump assembly/powerhead.

Aside from the Saturn C-2 having two completely different versions (pre Silverstein and post Silverstein commission) and the missing NASA S-III from said C-2 and the S-IVC that is a good collection of data there Friznit Yes the ETS S-IVC should really be the S-IVD NASA designed/designated a S-IVC as a 14.7 (ksp scale) meter long stage with a single J-2S engine. That would latter be rolled into the MLV as the MS-IVB-1A or -3 (at 14.67m KSP scale) Please note lengths be very subjective in space documents so... I am going to, this weekend, submit a FOIA for the Prelim design of the Saturn C-2 from 1960 to hopefully get more insight and design information on the Saturn S-III stage.
-
While the final product would have looked quite a bit different (the 4 tanks were of two sizes, and the engines were DIAGONAL to alleviate some of the asymmetry you were talking about,) This is very well done! Oh the Final version would have been jettisoned at fuel burn out as well to save precious dV. I think there was an option talked about for recovering the booster (as they have only enough fuel to get to about 15km altitude.
-
it is almost becoming a bad meme, even when un-intentional. =========================================================== Unrelated: Want to either A) thank the Dev Team for Fixing CADS... or B) thank Github for allowing me to download a version that works. I am back to building my Skylab Derived ISS.
-
wouldn't that be Atlas's Bouncing Big Baby Boi? Also a brief update on my Space Station and a RFI from others using the Apollo branch of the Github! You will notice that I have Zarya docked BELOW the Skylab core instead of inline with it. I am unable to dock Active to Passive, Passive to Passive or Active to Active with my CADS docking ports currently and am seeking info if this is happening to others as well. I launched the MOL based tug and Probe docking port as a test of other BDB docking ports (every one but CADS is working.) I launched 4 different launches to put a APAS port inline via the HABTECH adapter (I forget what the neck down part is called ATM)

J-2X "Aerobell" A semi flexible bell extension. this is not similar to modern 1,2,3 part bell extensions that we are used to as the material was flexible and actually changed shape during extension J-2X "Telescoping" A multi segment bell extension that was about 4-8 inches (estimate) thick . This was like 10 segments... so much like the 2 or 3 segment extensions we have but more complicated and harder to do (both IRL and in game) J-2X "Airmat" What is in BDB a flexible curtain that could fold up and would expand when the turbopump exhaust was ejected into it.
-
yes and much of the white in the "burnt" APollo capsule is actually caused by reactions with the salt water and the glue to the applique used for the silver insulation. Wait, real J-2X or fake "SLS- J-2X"???? Remember, J-2X was the name of a rocket engine family in the 1960s (we have one of the 3 variants in BDB!)
-
Confirmed, it worked for me. I dis-engaged autopilot on J2 burn out. Grabbed my payload, flipped and burned for Apoapsis until the PE was 120km with the SPS motor: CRAP was using the 1973 H-1 engines. Aside from that everything was as described. FULL HEAT SHIELD, Blk IV full up payload with RCS and CADS dockingport. *GUESS for Taintedlion.* You have a Life Support mod. It is adding weight. :shrugstar:
-
If you are using "standard" settings do this. Open the Ascent Path Editor... and turn off AUTOMATIC ALTITUDE TURN Then manually set your "Turn End Altitude:" to between 0 and 50km below your ideal Altitude for orbit... so long as the turn end is well above Atmosphere you are golden JNSQ the minimum you can set the end turn altitude is about 95km (I typically go for 150 or 200 as you see here the Automatic part assumes Stock KSP and forces Mechjeb to end the turn at 60km... regardless of if you are in atmo or not.

@TaintedLion@mozartbeatle Ok, so I have NEVER had luck with Mechjeb PVG. I don't use it it sucks. I used the classic assent profile in a build HEAVIER than you guys are dealing with for three reasons 1) I have a Hypergolic SM and SM engine (this gives me about +50dV over you but on the flip side it is a much lower TWR at takeoff and in space!) 2) I didn't use the amazing milkstool. In fact I removed it completely for the purposes of these tests (to eliminate anything it could add directly as a part) 3) I carried the Blk IV payload into orbit as you will see in the pictures. At 80km I had to shut off the Ascent guidance because it was commanding the rocket to crash back to Kerbin. I suggest this has nothing to do with the mod but rather has everything to do with Mechjeb. Mechjeb prioritized getting up to speed more than it did climbing even though "turn end altitude" was set at the 200km my orbit was set to. I ended up in a 277 x 161km orbit with plenty of fuel to de-orbit. In short, as the dev team is pushing these rockets closer and closer to reality, Mechjeb is having more and more problems with it.

sure but a 2nd hand source with no accurate cites are fully allowed so Wikipedia is still mob created trash instead of the goals of the founders. *SHRUGSTAR* You are using the obsolete part. search for LEO instead of Gemini It may not be unlocked at the point you are either. Further you are in Parachutes and not in the Control section where the OAMS actually is also are you DELETING the Bluedog_DB folder yourself or just letting CKAN do it (don't do the latter CKAN is great for installing new things, not so good when things get depreciated) Also it looks like

It is badly referenced on Wikipeda multiple times from other Saturn Articles for one thing. Further, for a brief period in 1960-1961 time frame (prior to June 1961) it was the defacto All up launch option because they were doing EOR instead of LOR. It was either build the spaceship in place with C-2 and C-3 or launch all at once with C-8

Flight to come later (things to do today and because I am an idiot and didn't convert the AJ10-137 to AZ50 yet!) But here is my Saturn VI. It is a No J-2 challenge Saturn V with Hydrolox S-II and S-IVB. Ok I know I created the challenge for myself but *SHRUG* To make this work better would need completely new S-II to S-IVB inter-stage, New S-IVB engine mount for 3 or 4x engines (I know they are coming!) But the engines have to point straight down (I will have to retain the standard Saturn S-IVB inter-stage on this flight as it will hang on 2 of my 3 engines I have using the LASS engine mount. A shorter S-II tank , AND OR a double LR87-LH2 Vac engine mount to allow enough thrust. 7 LR87LH2s are at 0.75 TWR for max S-II stage fuel. I may just make that a alt engine patch for the LR87-5 double engine... would use the sea level ISP on the dbl mount but would atleast get me the extra thrust needed. S-IVB needed to be stretched for the ISP + reasonable TWR with the LR87-LH2s I also considered a single LR87-LH2 + 2 A3 engines (RL10A-3 if you didn't know was briefly called the A-3 engine by NASA) (3 meter stretch) All of this could have been built instead of the Saturn V we have. I thought I would use the game to calculate out what was needed to get the magic Delta V to the moon in JNSQ and build a rocket with the appropriate stuff. I could launch this on 5 F-1s but found the TWR to be dicey and increase the chance of a failure (using R/W metrics) S-IC stage Stretched (6meter) 6 engine with standard F-1s (no F-1As here) TWR 1.47 at launch S-II stage: 7 engine mount, default length and 80% fuel and Ox LR87 LH-2 Vac engines S-IVB stage 3Meter stretch, LASS engine mount with 3x LR87-LH2-VAC engines, Outer engines are twisted inward slightly to hopefully (but not likely) clear the interstage standard LM and standard Munnar Apollo J class SM and the rookie move:

Looked at this drawing multiple times since it was posted. Realized those are double UA-120x SRM attachments.... Mmm imagine what you could do with double the SRM on your Titan... Your Saturn.... Your huddled bundled masses On to the reality of this drawing and why it is so wrong. 1) 3.5m SRM? Try 3.05m 2) ATK SRM? Try Chemical System Division of United Aircraft 3) 315ISP with 4x LR101s and a Vaccum Rated F-1? Try closer to 300 4) The F-1V again... the combustion chamber is drawn bigger than the standard F-1 (it looks like the smallest of the M-1 drawings in my opinion) 5) SIV-B stage as they call it. 6 RL10-A3s are not enough power to get a LOR lander and Apollo capsule into final orbit / inject for Moon. Probably better to go with: LR87-LH2s! It is not A J-2 engine and it was ALREADY DEVELOPED! Oh and it WON the Hydrolox engine competition with 11 of 12 goals met (J-2 only met 9 of the 12 goals IIRC) All that being said, interesting, if flawed concept. While I don't see a Kerolox S-II stage being a benefit, I do see the Vacuum F-1V (and F-1AV?) being a small but worthy investment for things like S-ID Then again, I also see the need for engine mounts for the LR87-LH2 (dual bell Sea Level and single bell Vac on multi engine mounts) on Saturn Nice flight. 100% Joking but White CM comes tomorrow
-
I would think the number quoted for ISP there is high... or the bell is much bigger than they are showing. Could do a "extension" bell that is small enough and brings you to ~300 second range I would think Do love the Airlit S-IC stage idea though Real world you run into problems with Airlit as the AJ260 has a LF-O fuel tank on top of it to be long enough to reach the S-IC-S-II interstage structure (where it's forces are applied) Of course if you are talking to a Saturn 1B or ETS Saturn 1E probably not an issue (freely admit I didn't go that direction when I wrote the above.)

First off , love the subtle (and not so subtle) changes to the textures InvaderChaos! As a guy who pushed and prodded for this I am very happy to see the update. But I have to ask, did you turn an Aussie probe into a Kinetic Energy Impact testprobe? I use to love the old Titan I "warhead" and use it as an impact probe. Scaled down some stock air-brakes to help slow it SLIGHTLY (If impact happens between the physics "frames"... something easy to do above Mach 1.5 it does not matter how strong the part is... it just ceases to exist.) Used several of DMagic's science tests on that probe.

Most of the Boilerplates have humdrum existences. With the exceptions of the Flight test articles that @Araym is doing an amazing job with. They are hum-drum Mass/size/displacement simulators for training people how to deal with the real thing. The bulk of these Simulators are made of galvanized steel and wouldn't survive a test launch let alone a landing. They were often placed where a recovery crew could practice the Post astronaut recovery. https://forum.nasaspaceflight.com/index.php?topic=26511.0 http://www.collectspace.com/ubb/Forum14/HTML/000089.html There is a Youtube video of the Restoration of at the New Mexico Space Museum... it is BP-1207... as you can see 1207 is similar to the picture for 1227. The Smithsonian has about 50 entries for Apollo Boilerplate... some are dupes but that means they own an aweful lot of them.

INT-20 and Saturn II we have in spades (the main MLV documents as well as the Saturn II documents are either on NTRS or other servers.) Any MLV variants are OK. So anything from the Saturn-I and the Saturn-V families are good. There are more like 8 or 9 C-3s. There are at-least 3 to 5 C-2s.... You see why I want those documents. I can always make more request in the future if my initial request goes through. There was no C-7 and C-8 does not interest me. If I were to jump on other rockets right away it would be some of the more unique Nova rockets.
