Thanks to both you and u/jansenart for your help in figuring out what is happening here (and to clarify for anyone else who comes to the post - highest in the sense that 2 is greater than -2, -3, -4, etc. That was the cause - I thought that each docking node pair had one 'crossfeed' option, not two (similar to how only one of the docking ports has a 'decouple' button when they are linked) it looks like they do need two crossfeed settings. However, it's all moot if I can't get the tanks to drain properly.Īny help or clarification about how the fuel flow and crossfeed work would be appreciated - I'm almost certain I'm making some really simple stupid thing to prevent it from working, but I'd appreciate any insight others might have. I really want to get this working - in my head cannon, the space agency decided that given the expense of nuclear engines and to avoid popular misconception about fall-out from destroying nuclear engines in the atmosphere when use is finished, the engines themselves would be re-used by being refueled, at least for a few missions (a la SpaceX style). While disabling the crossfeed still has the front tank draining first Having the flow priority reversed (tanks greater than the engine) and resetting the crossfeed displayed status to enabled still only drains the front tank Keeping the same flow priorities but setting the crossfeed status displayed to disabled also causes the front tank to drain. This (having the tanks less than the engine and crossfeed status displayed as enabled across all three docking ports) causes the front tank to drain. (BTW, in the pictures, there are 3 docking port connections - the space between the first and second of the four trailing pods is filled with a reaction wheel, and not a docking port) if it says crossfeed enabled does it mean crossfeed is possible at the moment, or does it mean if I click the button crossfeed will be enabled but for the moment it is disabled). I tried to do this via fuel flow priority and crossfeed, however no configuration of flow settings (either A being set greater than or less than the priority of the other fuel tanks) or crossfeed status being enabled/disabled (I'm trying both settings since I'm not sure if the 'crossfeed status' reflects what words are displayed or if it reflects what clicking the button will do - i.e. (if the engines are attached to tank A, with tank B, C, and D attached in sequence, I want tank D to drain first). However, I can't get it to drain the tanks other than the tank attached to the engines themselves. It has a single section with multiple of nuclear engines attached to it as a 'puller', which pulls via docking ports a set of fuel 'pods' - the idea being that the fuel drains from the pod at the end of the chain so that when it is depleted it can be detached and simply fall off once empty, to reduce mass. I have a new ship design, but cannot get it to work properly. Send us a message with proof, and we'll give you some flair to show it!
