Real Scale Boosters - Parts Pack Realistically scaled rockets, heavily based on real world counterparts, with reasonably accurate stats. --------------------------------------------------------------------- NOTE: This is still an alpha/beta development project. New parts are still being added, and things can and will change! --------------------------------------------------------------------- Required Dependencies: Module Manager Highly Recommended: Hangar Extender (practically a must-have) QuickSearch (you can just type "atlas" or "delta" or "saturn", for example, to find related parts quickly) Kerbal Joint Reinforcement (big parts = big flexing?) Real Solar System FAR Community Tech Tree (if not playing in Sandbox mode) Currently Supported: SMURFF (as in, we have flags set to keep it from overwriting our engine masses) TweakScale CommunityTechTree and/or SpaceY-Lifters's tech nodes Supported By: Real Fuels + Realism Overhaul (support is provided from their side) --------------------------------------------------------------------- Gallery: --------------------------------------------------------------------- Included Sample Rockets (as of 0.13): Ares I Ariane V Athena Ic Athena IIc Atlas V 401 Atlas V 431 Atlas V 502 Atlas V 532 Atlas V 552 Atlas V HLV Carrack Medium (ETS) Carrack Heavy (ETS) Delta II Delta III Delta IV M+ (4,4) Delta IV M+ (5,4) Delta IV Heavy DIRECT-Jupiter (theoretical) ISRO PSLV ISRO PSLV XL Saturn I Saturn IB Saturn IC (ETS) Saturn V Saturn C-8 (theoretical) Saturn Multibody Heavy H03 (ETS) STS (Space Shuttle) Lifter --------------------------------------------------------------------- NOTE: These rocket parts ARE NOT stock balanced! They're using the real world mass ratios, thrusts, ISPs, dry weights, and so on. They will certainly WORK in stock, just with severe overkill. SECOND NOTE: This is still in alpha/beta development. Parts are still being added, and things can and will change! --------------------------------------------------------------------- About: This pack is intended for use with "Real Solar System", or otherwise a more realistic scale version of Kerbin (such as 6.4x scale). The parts included will likely be severe overkill in a more normal KSP installation. This pack provides a variety of "Kerbalized" versions of real world boosters. These are not meant to be true replicas. Where we've been able to get decent numbers for the real world counterparts, we have tried to get the sizes, masses, fuel capacities (in terms of mass), thrust, and ISP numbers close to correct. The art assets attempt to capture the overall shape and look of their real counterparts, matching the colors and dimensions, but perhaps not all of the details. Precision wasn't a requirement in building this pack. Rather, it's meant to be closer to the "SpaceY" art style, but functionally replicating real boosters. You will also notice that this pack includes only the boosters, and not the payload portions of these rockets. For example, the Saturn V parts are included from the bottom, up to and including the third stage (and Instrument Unit), but no Apollo spacecraft. The Space Shuttle parts will build you a working LH/LOX tank ("soon") and SRB combo, but does not have an Orbiter. The idea is to build your own payload and use realistically performing analogs to the boosters used in the real world. To that end, some adapters and fairing parts are included so that other KSP parts will function with these boosters. While some parts already have a diameter close to a standard KSP size, they're still slightly different. If it's close enough, I've included a little bit of a rim that will help hide the transition when attaching stock parts. If it's too far off, an adapter is often the better way to go. For instance, the Atlas V's first stage is 3.81m. A simple rim works in this case when attaching a Kerbodyne 3.75m tank. --------------------------------------------------------------------- Usage Notes: * Inside the "Ships" folder, there are several example rockets already assembled. * None of the engines have bottom attachment nodes, or auto-shrouds. Instead, the mod functions more realistically, with interstages that are matched to the stages that use them, and engines can be mixed and matched inside of them (space permitting). Usually you will need to place the engines first, and then snap the appropriate interstage on afterward (whose attachment node may be hidden inside the tank). * Because different rockets historically have had different staging sequences, some of which place ullage motors on the interstages (Saturn V for instance), sometimes the stage's fuel tank has a decoupler node. Attachment nodes for the interstages may be hidden inside the tank butt, and usually are aligned with the exterior fuselage, rather than the end of a bulging dome or tank butt. * Realistic numbers have been used where possible, but sometimes available data online is rounded or imprecise, or have changed over the years so they are inconsistent. Numbers may be tweaked in the future if better information becomes available. Part sizes should be reasonably correct, but sometimes we lose a half meter or more somewhere. * In the available data, SRBs often are described in terms of either peak thrust, or average thrust. In the real world they have a highly variable thrust profile (by design). In KSP they use a single, invariant thrust level. We've opted for using a number somwhere between the average and peak thrusts. You may find the burn times shorter than the real world counterparts as a result, unless you use thrust limiting. * Real world RCS and attitude control thrusters tend to be very weak compared to what we're used to in KSP. For example the thrusters in the Delta IV upper stages are supposed to have less than 0.04 thrust. In KSP that feels almost useless, so we've opted for numbers closer to KSP's usual RCS thrusters. * By default RSB uses the stock LiquidFuel, Oxidizer, and MonoPropellant, but with the correct amounts of mass, so that the performance is consistent with the real rockets. Compatibility patches for Real Fuels (for example) should be forthcoming eventually. * These rockets are reasonably stable under the stock joint strength, and stock aerodynamics, since the part count is low. KJR and FAR are still recommended for a good experience though. --------------------------------------------------------------------- Known Issues: The Atlas V 500-series procedural fairing doesn't want to stretch straight up cylindrically around the Centaur at the correct diameter. It has to widen slightly first. Career-mode costs of parts and their unlocks are all out of whack, and need a balance pass. Wishlist / To-Do: Several generic radial decouplers and Ullage/Retro SRMs. Ariane V - (added in 0.5) - Possibly add ES variant? (maybe) DIRECT-Jupiter (shuttle derivative) - (usable, could use more parts) (maybe) Proton (Russian) (maybe) SLS, CDR version - (would love to, but multiple mods already have this) (maybe) Titan III family (maybe) Falcon 9R - (would love to, but multiple mods already have this) (maybe) Energia (Soviet) (maybe) PSLV/GSLV (Indian) - (PSLV added in 0.6) (maybe) Orbital Antares (maybe) Mercury/Gemini rockets: Redstone, Atlas D, Titan II (maybe) Tsyklon, Cosmos, Vostok (Russian) (maybe) Lambda, Diamant, Viking, Vanguard (maybe) Long March (Chinese) (maybe) H-IIB (Japanese) (maybe) N1 (Soviet) (maybe) Chrysler SERV (SSTO) (maybe) Thunderbolt (Eyes Turned Skyward) (maybe) (new) Juno I/II (maybe) (new) NEXUS more selections of realistic clamshell fairings --------------------------------------------------------------------- Installation: Simply copy the "RealScaleBoosters" folder into your GameData folder. If upgrading from a previous version, be sure to delete the old one from GameData first (this is the cleanest option). Troubleshooting: There's not a whole lot to go wrong in RSB by itself. If you are using the "stockalike" patches, some problems can arise due to either ModuleManager, or CKAN screwing up the installation/removal of various mods (and thus confusing ModuleManager), or maybe there is a new mod interaction that I'm not aware of. Some basic things you can do: Try deleting "ModuleManager.ConfigCache" in GameData. Always try this first. MM's cache can get out of sync and the only way to know that the problems you're having are real is to delete this file, and fire up KSP again, and let it rebuild the cache, and see if you are still having problems. Try completely deleting and reinstalling this mod, and anything else that might be interacting with it, such as mods that make sweeping changes to fuel tanks, fuels, engines, or rescaling. Make sure you have the most up-to-date version of this mod, ModuleManager, and anything else they might be interacting with. If KSP has just recently updated to a new version, some of these mods may be broken at first. If you're using CKAN and have removed any mods with it, recently or at any time in the past, make sure those mods actually are completely 100% removed. You may have to manually delete the folders since CKAN is very inconsistent about properly removing things and cleaning up after itself. Even if a mod's folder is completely empty, the fact that it exists will make ModuleManager believe that the mod is present. If you're loading the included sample rockets, and the size and fuel capacity is all wrong, make sure you're using the right sample rockets. For a regular RSB installed, they all have names that start with "RSB". For the "stockalike" patches, you should only be using the sample rockets that start with "RSBstock". --------------------------------------------------------------------------------------------------------------- Download From: SpaceDock -or- Curse.com -or- ksp.necrobones.com --------------------------------------------------------------------------------------------------------------- ***optional*** RSB Stockalike (stockification rescale patches) ***optional*** SpaceDock -or- ksp.necrobones.com --------------------------------------------------------------------------------------------------------------- Creative Commons 4.0 Attribution-NonCommercial-ShareAlike CC BY-NC-SA --------------------------------------------------------------------------------------------------------------- Change Log:

Hello there, so this is kinda a modding question. I currently play the RO/RSS version installed via CKAN(1.3) and i love the realscalebooster mod. Now my problem is that with the Delta III/IV upper stages and their low TWR(0.5-1.0) i just can’t make it into orbit. How do I need to adjust my flight profile so I get into a stable orbit before I drop back into the atmosphere? Don’t mind to ask further questions to get more infos. Thanks in advance

Hello once again, people. I've got a rookie Realism Overhaul question for you. I downloaded Realism Overhaul manually, and added only the parts that are indicated "necessary for the mod to work correctly", via CKAN. The cause of this was the fact that CKAN couldn't download RO, it kept failing every time. Thing is, it looks like solid rocket boosters of any kind, although loaded with what is indicated as PBAN, they won't ignite, because of "fuel deprivation". I can't, however, load the tank with any other fuel. Does anybody know of any mods that control the fuel or this behavior?
