It's not Sigma based.~~\r\n\r\n`Compatibility\\Rescale\\BlueSmurff.cfg` is the file we're working with.\r\n\r\nIf you're familiar with SMURFF, this is based on that. We're reducing the dry mass of various parts to get the deltav we want. What gets reduced and by how much is determined by the rescale value from Sigma. Adding fuel is an option, but we want to exhaust the mass possibilities before throwing more fuel in.\r\n\r\nThings we need to know to make adjustments:\r\n\r\nHow do the non-manned rockets fly with payloads. OP/Under-P/About right.\r\n\r\nDo Mercury Atlas and Gemini Titan make orbit without too much excess dv. (No using the SM engine or mercury srbs.).\r\n\r\nSaturn is a top down problem that should be done last, but we need to keep an eye on it. Enough dv for LEM ascent/descent, CM dv to circularize and return, S-IVB TLI burn, and then the S-II/S-IC stages. We want the S-II to burn out short of making orbit, but not so short the S-IVB can't do the TLI. We have ballast mass built in to Saturn that can be removed to tune the various stages.\r\n\r\nRight now the settings look ballpark correct. We need to pretty much fly everything in every rescale and make sure."},"comment":{"url":"https://api.github.com/repos/CobaltWolf/Bluedog-Design-Bureau/issues/comments/260290125","html_url":"https://github.com/CobaltWolf/Bluedog-Design-Bureau/issues/270#issuecomment-260290125","issue_url":"https://api.github.com/repos/CobaltWolf/Bluedog-Design-Bureau/issues/270","id":260290125,"user":{"login":"jsolson","id":16825376,"avatar_url":"https://avatars.githubusercontent.com/u/16825376?v=3","gravatar_id":"","url":"https://api.github.com/users/jsolson","html_url":"https://github.com/jsolson","followers_url":"https://api.github.com/users/jsolson/followers","following_url":"https://api.github.com/users/jsolson/following{/other_user}","gists_url":"https://api.github.com/users/jsolson/gists{/gist_id}","starred_url":"https://api.github.com/users/jsolson/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jsolson/subscriptions","organizations_url":"https://api.github.com/users/jsolson/orgs","repos_url":"https://api.github.com/users/jsolson/repos","events_url":"https://api.github.com/users/jsolson/events{/privacy}","received_events_url":"https://api.github.com/users/jsolson/received_events","type":"User","site_admin":false},"created_at":"2016-11-14T09:42:21Z","updated_at":"2016-11-14T09:42:21Z","body":">a) mesh switching on the engines\r\n\r\nDo that. If I understand you, there will be one of each engine, each with 2.5, 1.875, 1.5, 1.25 (down to whatever size the bell will fit in), and no buttplate meshes. 2.5 for the SM engines and no buttplate for the other two should be the default since those are their primary uses.\r\n\r\n>b) node switching to account for any differences AND enable/disable the extra SLA node\r\n\r\nNot required with above. The engine is tall enough to separate the nodes.\r\n\r\n>C) adjust the mass if the buttplate is on - though I think it deserves to be aesthetic at this point.\r\n\r\nI say we go with aesthetic. We don't account for buttplates on other engines."}}
