NathanKell Posted February 19, 2016 Share Posted February 19, 2016 Here's more about the size I'd suggest. Uses only TL2 stock parts (LR79-NA-11 with LR101x2, S1.5400/11D33, Hydrazine and NTO/UDMH RCS,). Requires what RO requires (parts beyond stock are Proc Parts, Proc Fairings, VSR, RemoteTech). The payload is ~550kg, a Ranger Block III core with two solar panels, a dish, and two antenna, with four of the smallest RCS and (of the 550kg) about 400+kg is hydrazine, so you're looking at probably 2500m/s in it. Lots of station-keeping. You should only need 9300m/s so the payload capacity can probably stretch to 600kg or more for LEO. If you use nearly all the hydrazine in the payload, you could probably do a Molniya orbit. https://www.dropbox.com/s/lvw8sfj9x9blz58/Example.craft?dl=0 In the VAB Note the real delta V is slightly lower since this is shown with half the fairing sides present. Flight is a simple gravity turn, pitching below prograde near burnout to not get too high an apogee (don't go beyond 2-3 minutes to apogee on the first stage). Second stage will need to pitch above prograde once time to apogee is below 30s or so, or apogee rises above 180km. You should easily be able to do a 200x200 orbit with no relights, though the stage does support relighting (use the 4x seps in it for ullaging, or the built-in RCS).

The -27A should be on the core and the sea level config (H-1SaturnIB or RS-27) should be on the boosters. Also, you would do much better IMO with only 5 core RS-27As not 6 (4x in a cross and one in the center) and a core stretch of another 45t of propellant (I used a Tantares Proton Upper Stage tank and refilled it with kerolox). That raises payload to ~14.5t. @MysteriousSteve yeah, that lifter is about 15x (or more) as much as you need, if the payload is going to be less than a ton... BTW, that's not my booster... I just put it on KerbalX to get the mods. Link to comment Share on other sites More sharing options...

The reason the booster was not originally optimized for the payload was that we had a bunch of designs to be made, running from 1 to 15 tonnes, and all the way up to some SHLVs. It was going to be too much work to make individual designs, do we made a bunch of stock models. And btw, the booster design credits go to @Joco223. And it's awesome to have your expertise, Nathan!

NathanKell Posted February 19, 2016 Share Posted February 19, 2016 @CliftonM @Dman979 @Joco223 apologies for the mixup! And also, I didn't realize until today this thread was in RO, I'd sure have been hanging around had I realized that from the start. I love this sort of thing!

MysteriousSteve Posted February 19, 2016 Share Posted February 19, 2016 (edited) So, it's pretty crude, can definitely be improved, but here it is. Edited February 19, 2016 by MysteriousSteve Link to comment Share on other sites More sharing options...

NathanKell Posted February 19, 2016 Share Posted February 19, 2016 @MysteriousSteve that seems...a bit under-delta-V'd. That nine and a half minute upper will incur enough gravity losses that you'll need more than 9.3km/sec anyway, let alone the 9.0km/sec provided by just the lower and upper stages during their combined 12.5 minutes burn. Also you probably need more than just those RCS thrusters for roll control during lower stage burn, but it might be ok. What upper stage engine are you using, anyway? I don't recognize it...

Yes, it's in client. You need to go into options - export whitelist. It'll be alongside your ksp application, not in GameData. Link to comment Share on other sites More sharing options...
Dman979 Posted February 19, 2016 Share Posted February 19, 2016 Hey @ZooNamedGames, I will be offline from now until 13:00 EST tomorrow. I won't be able to respond to anything before then. Also, have you thought about making a set of comms guidelines for us? And perhaps rules for the stream? Link to comment Share on other sites More sharing options...
