After that's ongoing I will focus on IVA for both BFR and Dragon! Quote Link to comment Share on other sites More sharing options...

What are you going to base the BFS IVA on? There currently aren't any images of its interior. Quote Link to comment Share on other sites More sharing options...

I would love to see this design, but doesn't really seem practical with 5 m diameter. The kerbals would not have enough personal space....

JadeOfMaar Posted October 5, 2018 Share Posted October 5, 2018 @Starwaster Sweeeet. May I ask where you got that engine propellant config from? Quote Link to comment Share on other sites More sharing options...
Starwaster Posted October 5, 2018 Share Posted October 5, 2018 1 hour ago, JadeOfMaar said: @Starwaster Sweeeet. May I ask where you got that engine propellant config from? It's what I use locally. The units are volumetric of course but both the stock engine and RCS code normalize any provided values and then scale them as necessary for the configured thrust and propellant density. The specific values are reasonably accurate... or accurately reasonable in that they are a typical mixture ratio for 'methalox'. They may not however accurately reflect the final mix ratio in the Raptor or methane powered RCS since there both have yet to be fielded in flight. One other thing I'd like to mention here is that methane is getting serious consideration now as an RCS propellant for Mars landers (for both sample return and MAV landers, with their own propellant generation) for pretty much the reasons provided, where previously there hasn't been much talk about doing so.

My Vulcan build uses it for his twin BE-4, but in a more simple 3 to 1 ratio: @PROPELLANT[LiquidFuel] { @name = LqdMethane @ratio = 3 } @PROPELLANT[Oxidizer] { @ratio = 1 } Just add this to cryotanks CryoTanksFuelTankTypes.cfg B9_TANK_TYPE { name = MethaneLOX tankMass = 0.00 tankCost = 0.00 RESOURCE { name = LqdMethane unitsPerVolume = .375 } RESOURCE { name = Oxidizer unitsPerVolume = .125 } } B9_TANK_TYPE { name = Methane tankMass = 0.00 tankCost = 0.00 RESOURCE { name = LqdMethane unitsPerVolume = 1 } } and to CryoTanksFuelTankSwitcher.cfg SUBTYPE { name = MethaneLOX title = LCH4/OX tankType = MethaneLOX addedMass = 0 addedCost = 0 } SUBTYPE { name = Methane title = LCH4 tankType = Methane addedMass = 0 addedCost = 0 } Quote Link to comment Share on other sites More sharing options...
JadeOfMaar Posted October 6, 2018 Share Posted October 6, 2018 (edited) 21 minutes ago, Drakenex said: Just add this to cryotanks CryoTanksFuelTankTypes.cfg Concerning your tank type config, it looks to me like you're losing out a bit (afaik). Except for really low density resources (LH2 and ElectricCharge) the sum of resource ratios therein tend to be 1, so I would double the values you have set there for MethaLox. I rather like your very simple 3:1 ratio, meanwhile I had a hard time understanding new fuel ratios and coming to accept the one I use: 57:43... But this is for a Classic Stock (see Angel-125's mods) equivalent fuel mix: Raptium & Oxidizer. I've considered adding to the next Tundra Exploration release a sweeping change that will make all its raptor-themed engines require CRP's LqdMethane and not LiquidFuel, but I expect the players at large would be unhappy with something like this-- and I haven't even tested it yet. The trouble to setup and balance everything around it may outweigh the gameplay benefit of handling Methalox in-game. Also, I don't know if there's sufficient demand for this anyway.

I'll have to test them, but proportionally is the same (doubling values). May be the only issue with my config is having to add much more fuel in orden to switch from LF/OX to MethaneLOX.

JadeOfMaar Posted October 6, 2018 Share Posted October 6, 2018 @Drakenex Yeah. I expect it'll be just fine. You'll just be getting twice the fuel in the tanks that you're accustomed to, and a rightful amount to expect. You shouldn't have to spam tanks as though you were using Hydrolox. It'll be a dark chapter in spaceflight history if Methalox rockets start looking like actual blimps. Quote Link to comment Share on other sites More sharing options...

Damon Posted October 6, 2018 Author Share Posted October 6, 2018 I've added the 2018 BFR parts to Github!BE AWARE!This is pure a test build. DO NOT use this with your current save! Things that are added: BFS Command pod BFS fuel tank BFS Engine Shroud SL Raptor engine 2 actuated fins 1 fixed tail fin BFB Interstage BFB Fuel tank BFB Engine cluster Massive thank you to @JadeOfMaar for helping me out getting things fairly good balanced! About re-entry: Please be aware that the BFS is very unstable during re-entry. Any help or tips to improve this is highly appreciated! There's a craft file in the Ships/VAB folder to try out and see how things are set up. Happy (test) launches! Quote Link to comment Share on other sites More sharing options...
