Of course this is due to the awesome throttle-range of the Atlas' RD-180, whereas the F-1 could not be throttled at all. But the F-1 could be shut down early in flight correct? So starting off with say 4 engines, then shutting down a pair of outboard engines early would preclude a huge G-load towards the tail-end of the first stage? Of course then I suppose you are accepting that you've basically paid full price for a pair of F-1 engines to be useful for half of the mission, and dead weight for the second half.

Couldn't an F-1A be throttled to 70%? Anything after the initial order of Saturns would've used those engines instead. Quote Link to comment Share on other sites More sharing options...

I am a fan of the three engine version of the INT-20. It cuts back on some of those dodgy acceleration issues while still maintaining a LEO payload considerably superior to the Saturn IB.

It used Hughes HS 308 satellite bus - a cylinder 2.8m in diameter, covered with solar panels. Think BIG Pioneer 6 (without motor, although it was added in later HS series buses). While "cylinder" part is not a problem, "covered with solar panels" is. Curved solar panels are extremely rare feature in KSP mods - I know only of NFElectrical, and these are too big for KSP-scaled HS-308 (should be either 1.25m or 1.5m). Thus, I humbly request several parts which can be used to make a HS-series cylindrical satellite buses. Mainly HS 376 (since it has some notable and fun features). Suggested parts: - Probe core: 1.25m diameter, cylinder about 0.5m height, gray color. SAS, reaction wheels, about 40 Ec. Has built-in RCS with tiny monoprop supply. - Equipment bay: Same dimensions as probe core, covered with solar panels, empty shell with toggleable endcaps. You can place anything you want in it, including other probe cores (to make pre-376 buses). Make a sandwich with probe core to make HS 376 main body. Toggleable node for telescopical solar panel (see below). - Telescopical solar panel: No, I'm not kidding. Diameter slightly larger than 1.25m (to accomodate satellite main body). Height of about 1.5m, attaches to aforementioned toggleable node. EDIT: Sorry, pasted wrong link (that particular page can be accessed only via Wayback Machine). Fixed.

Anything after the initial order of Saturns would've used those engines instead. Yes the F-1A could be throttled to 70%. However it was not intended for the F-1A to replace the F-1 in ALL configurations (the core MLV study showcases this by having several MLV rockets listed with 5 or 6 F-1s and grossly similar rockets with 5 F-1As. ) Most of the INT-20 documentation I used to write the article specifically cited F-1 engine and F-1 Engine thrust. This is one of the reasons I said the INT-20 was Boeing trying to spite everyone else just to keep "their" stage in production. They cut all "new" or "growth" costs out of the proposal and stuck with a bone stock S-IC for their proposal. I had only found anecdotal references to the F-1A in the INT-20. All that being said, I have recently had a discussion with other data miners / History Collectors like myself. Everyone other that me stated that the INT-20 was where NASA should have focused. To keep the S-IC stage. This is to the exclusion of the S-II stage... which to me begs the question... Whats the point? Keeping S-IC alone does nothing for your goal of keeping a major rocket in production. What it does do is keep the F-1 engine viable... There are other ways to do this that do not waste production capabilities in my book. Conversely, I look at three of the INT-x proposals as the go to because with these three, you cover payloads slightly larger than Atlas-Centaur all the way up to full on Saturn V. I call it Dial a Saturn Saturn II- INT-18.5/INT-18.7 (including 2x 4x and 5x SRMs) Saturn II-INT-19 (with Select-able M55 SRMs from 4 to 16) If this went into production I would assume some non-Minuteman SRMs would replace the M55s for Strategic Arms treaty enforcement. Saturn INT-21 INT-18.7 with 5SRMs can lift ~96% of what INT-20 could lift at 3.6G The problem with using the Saturn II rockets is the SRMs. IN the 1960s stacking SRMs is not an expensive process... By the 1980s it is hugely expensive. The Saturn II-INT-19 is the most cost effective launcher of the three. But it is also the lowest performing. But it's performance is actually better than any of the INT-18s with 2x SRMs. Ground logistics wise you end up with 3 new launch pads, and keeping LC-39 for the INT-21/ standard-ish Saturn V. The INT-18 (x2) plus INT-19 would ride on one pad, the INT-18(x4) would need a second and because of the 5 SRMs in a pentagonal arrangement you would need a 3rd pad for the INT-18 (x5.) I know the mass of a UA-1207 is pretty hefty but I always imagined that the bare rocket would be moved to the pad on a small crawler and then the empty stages (and payload) winched into place on the stand.... then from horizontal "roadable" buildings the UA-120x would be elevated to the correct point for joining the MS-II stage on the launch stand. much like you see the old coffin launched Atlas ballistic missile (and IM-99 Bomarc) elevate from low profile buildings to fire.

pTrevTrevs Posted December 29, 2021 Share Posted December 29, 2021 A little preview of the Falcon on the plain at Hadley: Unfortunately I'm having some issues getting the LRV to unfold. Right now I think it has to do with the rover being slightly larger than the empty bay for it in the J-series descent stage, and I don't know if there's an easy way to fix that in-flight, short of tampering with my persistent file to have the hinge be unfolded already. Hell, I feel like that would cause more problems that it's worth. Worst case scenario, I hyperedit a new rover up there and continue from there, but I don't think I'll be getting this done anytime soon. In the meantime I have some satellite launches to show off, I guess. KH-1 Hexagon on Titan-IIID: Quote Explorer 43 on Delta M6, anachronistically launched to heliocentric orbit, because the spacecraft's historical MEO/HEO regime was tapped out in terms of solar wind and charged particle science: Quote DSP 1 on Titan 23C. This spacecraft was the first in a series of satellites designed to detect ICBM launches and nuclear detonations, both to safeguard NATO against a nuclear strike and ensure compliance with nuclear test ban treaties: Quote Of course, I don't get anything out of launching a satellite like this, but it's fun to pretend. Maybe someone should set up a contract pack for military orbital launches, with orders for navigation constellations, missile detection satellites, SIGINT and ELINT payloads, and good old-fashioned optical reconnaissance spacecraft.

I've had this issue before with robotics. Of course it might not be related to yours, but could be worth a shot: Try setting Autostrut: Disabled to all parts of the Rover after you've landed and are ready to unfold, including the hinge mechanism.
