I know the theory; but trying to apply in a pretty way and also avoid the weight creep that is run into by needing solar or other power supply, I am starting to see just how much of a challenge NTR can be to make weight efficient and also the complexity that it can add back in.

Yes, keeping the system cooled can be hard, but even if it is a little heavier, it's worth it, specially if you extend the stage. You could also keep only the NTR cold, and refuel the S-IV in orbit, wich could help with avoiding radiators Quote Link to comment Share on other sites More sharing options...
RocketBoy1641 Posted July 3, 2023 Share Posted July 3, 2023 I fixed my high temp loop question. It turns out the Timberwind 75 has a really tall core. Tall enough that a wink and a nudge says that the engineers designed it to hang a pair of XR-600 High temp radiators off of. And they don't ruin the tank asthetic that way Quote Link to comment Share on other sites More sharing options...
RocketBoy1641 Posted July 4, 2023 Share Posted July 4, 2023 Really feeling silly right now. I used to know all my parts mods frontwards and backwards; for the life of me, right now I can't remember the one that has the half ring surface mounting 3.5m and 5m reaction control wheels. Stretched tanks are acting a little wobbly on this behemoth. Anyone recall what mod that is? Quote Link to comment Share on other sites More sharing options...

RocketBoy1641 Posted July 8, 2023 Share Posted July 8, 2023 Here is my go at Apollo 13 CSM using the SIM bay for the module that blows. Based on photos that is the correct one (note antenna in historical pic). I rotated the two fuel cells up to mimic what the crew described. At least portions of all tanks appear in the historical references, so I didn't omit any. I skipped the debris of insulation etc as that would be difficult to accomplish. Latest from a mission: We have a J Series mission with an Apollo 15/16 SIM bay and J class lander. I did embellish the lander a bit with a couple small round mono tanks and a battery in the leg quadrants. Also, while not in this morning's screenshots, I verified a fuel cell powered S-IVB stage able to have post separation maneuvers done to facilitate Lunar impact or sending out into heliocentric orbit. With some conservative fuel consumption and the Skylab roll out solar panels and a relay antenna they could also be used as relays around Luna/Mun. Those images will come tonight. There were plans considered to do relays during the flyby into heliocentric orbit to facilitate far side landing or to just eliminate the communications blackout. This wasn't actually done though. On an interesting note for delta-V there was only 44 MPH difference between TLI burn and setting up for Lunar impact and only 88 MPH difference between TLI burn and heliocentric injection of the spent stage.

Galland1998 Posted July 8, 2023 Share Posted July 8, 2023 What is the current thinking of the best tech tree to be used with BDB parts. Ideally, I would like to do an "uncrewed" start.

RocketBoy1641 Posted July 9, 2023 Share Posted July 9, 2023 (edited) The first couple are where I added a battery and fuel cell to do prolonged stage control. IMHO, the battery is unneeded; but it is small mass in the big picture, and is a safety massive safety margin adding 2x the electric charge storage. This moves on including stuff to make it a relay. In theory after your fourth third (edit) moon landing with one of these you have uninterrupted communication back to Earth/Kerbin. I didn't strip the relay stuff off of this; but it shows how the XR-600s fit nicely on the Timberwind-75. Back to some more of the relay.

RocketBoy1641 Posted July 10, 2023 Share Posted July 10, 2023 (edited) Here are a few captures from a quick test run of the Lunar Mapping & Site Survey Mission (LM&SS) configuration. NASA actually still owns the hardware for two KH-8 Keyhole satellites. For this versioning of what it looks like we use pure BDB parts. It has the KH-8, a AARDVRK cone and a LM docking port. I used a Apollo 17 CSM in the test. If you look carefully, you can see the SIMs cover AND the S-IVB in at least one image. The S-IVB is on a line parallel to the KH and in line with the SIMs bay cover. If you look for the quad panels (attached) forming a bit of a cross, you found it. In the alternate that I am working up the LM&SS will most likely fly as Apollo 15 on the 28 day marathon to get better 'site truth' imaging before the K missions on 16 to at least 20 (have yet to determine when the "L" non-historic follow on missions will be started).

Understand irl constraints and they design may be on other things currently. Insert Cobolt saying the other guy who did the lander part is pretty busy,IRL Insert Cobolt saying it would take several Months (circa April/May). Insert me going nuts seeing post about Viking III rover and going nuts for it. On 6/13/2023 at 2:58 PM, CobaltWolf said: There is no proper version of that motor, no. It's a lot more work than it looks, you never wind up being able to reuse as much as you'd like from the existing model. Not only that, but the stock wheel system doesn't support tracks like that. In any case, there's still a ton of work to do for the flown Viking parts, so let's not get ahead of ourselves. That will take up my entire summer, if not more - even small requests are time consuming and require me to sustain interest for several weeks or months. By the time I get to that point I'll likely be ready to work on something different. My guess is we should be thrilled if we get it for Christmas. If sooner: Insert gif of guy handing Cobalt buckets of cash! Edited July 11, 2023 by RocketBoy1641 Quote Link to comment Share on other sites More sharing options...
Invaderchaos Posted July 12, 2023 Share Posted July 12, 2023 Syncom now on the BDB github! The world's first geosynchronous (Syncom 2, via Delta B) and geostationary (Syncom 3, via Delta D) satellite. This satellite is fully balanced, so a Delta B should be able to place Syncom in an inclined geosynchronous orbit on KSRSS Reborn, and a Delta D should be able to place Syncom in a geostationary (0 degree inclination) orbit.
