I have a fictional solution I made 2 INT-17 variants INT-17A, no stretches, uses RL-20s INT-17B, correct tank stretches, it uses J-2T400Ks INT-17 is weird but I still like it Quote Link to comment Share on other sites More sharing options...

Interesting to hear that J-2T400Ks where actually proposed at one point for INT-17, I didn't know back then that they where, I just used the strongest and most logical (no M1) Hydrolox engine. I thought about using the normal J-2T or the 1st upgrade for it, but they have worse ISP so I also used J-2T400K on the 2nd stage Quote Link to comment Share on other sites More sharing options...

MajorLeaugeRocketScience Posted December 12, 2021 Share Posted December 12, 2021 (edited) Saturn MLV V-42-4(L)-B sits on the pad (I use my own MLV designations to make it a little simpler: The V refers to Saturn V derived, the 42 refers to 4th generation, 2 stages, the second 4(L) refers to 4 liquid boosters, and the B refers to to the second available size of boosters (two engines each). Stage one and boosters are powered by a total of 13 F-1B engines, and the second stage is powered by 5 J-2A-2 hydrolox engines Payload can be further expanded by adding an MS-IVB third stage and adding an additional 2 J-2A-2s to the MS-II. This 2-stage variant is intended to launch ultra heavy payloads to LEO or self propelled payloads directly to the moon.

INT-17, the "HG-3" powered (notice the quotes please!) Needs either RL-20P3 engines in the first stage or the XLR-129s. Those are the best engines for the fit. ALSO needs LESS Than full fuel (as designed.) I wrote an article on the Saturn II a couple months back let me reference it for INT-17.... Oh and you need the 7x engine mount, not the standard 5x Engine mount. First to quote my original document: Quote INT-17: INT-17 was a paper study that latched onto the Paper engine known as the HG-3. The goal was to showcase that while high-power engines COULD be made, putting them on a Saturn S-II(C5) stage would not make it fly well or with a viable payload. This was done as a contrast to the latter INT-18 and INT-19 proposals for Saturn II which both showcased that with existing technology, it was cheaper and effective to replace the Saturn I completely with Saturn V derived components. The above quote means INT-17 is at best a PIG and not really a productive Rocket. The Original document that lead to the INT-17, INT-18 and INT-19 "Adaptation of the Saturn S-II stage for Ground launch" specifically calls out that any S-II derived Launcher would need augmented or 0 stage thrust to carry a workable payload. The document cites the Minuteman SRM (AKA INT-19,) and the UA-1205/UA-1207 SRM (AKA INT-18) as well as a NO S-IVB UA-1205 rocket (Which was dropped from the actual final document. The Final INT/MLV document on the Saturn II points out that the first stage needs something like 2/3rds max fuel and the S-IVB needs something like 50% max fuel to attain orbit with a 5000lb payload (I don't have that document well sorted at the moment and am looking for it (Will update when I find it.) IE for the cost, just throw your 5000lb payload on a Delta or an Atlas Centaur and you are more efficient in $$$ to launch. *EDITED FROM HERE ON TO NEXT ** comment* So the Initial study I quoted, had the HG-3 engines in a 7x array and needed a reduced fuel load (I still haven't found the document that actually calculated it out but I can tell you Wikipedia is dead wrong if you build it with 7 RL20s or XLR-129s for throw weight. Again HG-3 was a paper engine and the 1964 document covering the INT-17 is also a theoretical paper and was never intended to make hardware. It appears that Pratt and Whitney's theoretical dream pipe HG-3 had some problems that could not be solved with then state of the art engineering, but with 20 years give or take would result in the superior turbo pumps used on the RS-25/SSME engines for the Shuttle. A latter Boeing study re-investigated the INT-17 as part of it's MLV-SAT-V3B. This INT-17 (yes lets call it INT-17A) is stretched by 15.5 or 16.5 feet (depends on the copy of the report but both numbers appear) Full fuel load and 7x J-2T-400Ks as mentioned previously by @Starhelperdude above (good guess BTW!) @Jcking of course tied the correct guess all up with a pretty bow for us MS-IVB also 16.5ft long and also with a single J-2T-400K engine. 136k lbs to LEO at 72 degrees. Report is "Study of Saturn and Intermediate Vehicle Improvement Programs: Executive Summary Report" dated 04/16/1968. This is a Marshal Space Flight Center summation of the various INT and MLV reports up to this date. *End Edited Content* 8 hours ago, MajorLeaugeRocketScience said: I use my own MLV designations to make it a little simpler Neat rockets. I should note that each vendor used their own designation systems in the MLV rockets. The only unified designations appear to be the LEO INT series of Saturn Rockets.

Saltshaker Posted December 13, 2021 Share Posted December 13, 2021 Does anyone have a good Mun rover craft/subassembly file or ideas on how to stuff one into the J-class LEM bay?

You might be able to store the bulkier parts in the descent stage’s inventory slots and have a Kerbal attach them on the surface during EVA, but it would be a pretty awkward solution no matter what.

I don't use BG or other robotic parts mods. I figured this is the best place to ask. I have a good design, it uses a combination of DLC and mod parts. It is a reasonably close approximation to the historical LRV. the problem is that it is too big for the BDB LM, even when folded. I am working on trying to Tweakscale it down, but I am running into some hinkiness with that while trying to attach the folding rover wheels. The other issue is developing a useable descent stage deployment mechanism. The #1 issue is that the scale chosen by the BDB dev team does not match the scale of the stock and DLC parts. Neither party is wrong here, both had justifiable reasons for doing so. But it does make kitbashing a historical-themed LRV for BDB use a bit more difficult. I may end up landing it separately.

DaveyJ576 Posted December 13, 2021 Share Posted December 13, 2021 So, I have been working the Saturn revamp branch, experimenting with some Apollo Applications Project (AAP) concepts. The first part is related to mission AAP-1A, which was the first scheduled mission for AAP, to have taken place some time in 1969. It obviously never flew. Spoiler Spoiler The docked experiment carrier is a kitbash of this official concept: Spoiler It was essentially a framework to which various cameras and sensors were attached, and it had a conical pressurized section in the center that served as a control station for the experiments. My kitbash is a little smaller than the real one would have been. It is a combination of a Mercury capsule and Coatl's Surveyor bus. I then slapped on a variety of experiments. Not an accurate recreation by any means, but close enough for government work. I am now working on the Wet Workshop. Below is my recreation of the ATM for the AAP program. Spoiler Does anyone have an idea of how to attach this to the SLA? Without a node on the bottom you have to do a lot of adjustments. The existing framework options that @CobaltWolfadded helps, but there is still no way of attaching it to the SLA. Quote Link to comment Share on other sites More sharing options...
