The TR-18A Stack Decoupler is a Decoupler that allows for staging rockets vertically and in sequence. It is also the only stack decoupler in the demo version of the game.

Usage

The TR-18A adds a stage to the rocket and when activated will jettison anything attached to it. Unlike the TR-18D, the TR-18A remains attached to one side of the rocket - the side facing away from the arrow on the decoupler. It is primarily used for jettisoning spent stages or drop tanks with a 1.25m node.

Product description

The TR-18A Stack Decoupler is equipped with a (hopefully) small explosive charge, that will sever the structural linkage between itself and whatever it's connected to. Painted on its sides are handy arrows indicating which side will detach.

Changes

1.4
  • Hidden from tech tree and part list
0.18
  • New model and texture
0.15
  • (undocumented) Stack Decouplers no longer cross-feed fuel by default.
0.14
  • Decouplers now obey the second law of physics (Acceleration = Force/Mass)
  • (unimplemented) Increased the ejection force of Decouplers and Radial Decouplers (too underpowered after the physics fix).
0.9
  • (undocumented) Decouplers can now cross-feed fuel.
0.8.5
  • Stage decouplers can now share fuel across stages.
  • Fixed a bug where creating a new stage with a decoupler and then removing it would generate errors.
0.7.3
  • Initial Release
