Then find it in the editor by name (it looks differently now). Changed the flow direction, so fuel will flow from the first-placed end of the line to the second end. For the fuel transfer you need to use RTS-1 part.However, to do this, two fuel lines need to be connected, one in the direction of the intended transfer and one in the opposite direction.Īs of version 1.10 this part has two variants that can be switched in the editor. Nowadays, most of this is done by setting the flow priorities appropriately, and fuel lines are no longer necessary for asparagus staging.įuel lines can be used to transfer fuel past parts that normally don't allow fuel transfer, such as heat shields.
KERBAL SPACE PROGRAM CONTROLS TRANSFER FUEL FULL
By the time the last external fuel tanks are jettisoned, the central or main fuel tanks left on the vessel will be at a full fuel level. The FTX-2's links provide additional strength and stability, somewhat like the EAS-4 Strut Connector.įuel lines used to be a vital part of asparagus staging designs allowing for use of all engines available where fuel is first drained from external fuel tanks allowing them to be jettisoned (severing the FTX-2 External Fuel Duct) when they become empty. It is important to observe the arrows depicted on the fuel duct as they provide a visual cue as to the direction of the fuel flow.Īny part connected to a fuel line will allow fuel flow from the fuel line, even if fuelCrossFeed = False in its CFG file. The line must be first connected to the source for the fuel then to the destination of the fuel. The FTX-2 allows fuel not directly connected to an engine to be used. After the recall of the FTX-1 series, All FTX-2 lines have arrows painted on to indicate the fuel flow direction, so engineers can tell which way around they are supposed to go. Altough criticized by some as being no more than 'a sewage pipe painted yellow', most agree that the yellow is a relatively nice color, and that fuel lines are indeed able to pump fuel from side-mounted fuel tanks.
New breakthroughs at FLOOYD Dynamics have made the FTX Fuel Duct a reality.
