The TT18-A Launch Stability Enhancer is a stability clamp system designed to hold the ship at the launch pad before lift-off.

As of version 0.19.1 the staging sequence lists the TT18-A as a strut item and not a decoupler. Given the reduced number of parts shown in the staging display post 0.18, this may be a feature.

Usage

The launch clamps prevent unbalanced craft from falling over, and heavy designs from crushing themselves when they first load onto the launchpad.

When using the TT18-A, keep in mind that it must be decoupled to allow lift off. When the rocket is very powerful, engaging the engines without decoupling can lead to a grand catastrophic failure because it tears the structure apart. A simple solution is to release them in the same stage with the main engines. This way they will release the same moment the engines engage, resulting in a satisfying “clunk” sound as your ascent begins, and a hopefully intact craft. Some smaller rockets, like the Kerbal X, can safely have the engines in a stage before the TT18-A as the thrust is not enough to tear it apart.

It is always a good idea to activate SAS before launch, as the TT18 decoupler may occasionally push a rocket off vertical and lead to a failed launch.

Jet powered first stages, as they need to spin up, should be decoupled as soon as they are running at full throttle. If other rocket engines on that stage are used as well, the staging should:

  1. Start the jet engines,
  2. Decouple the stability enhancers and start the rocket engines.

If there are TT18-A left from the previous launch they will be removed prior to placing a new craft there. While in previous versions[specify] it was needed to be confirmed, this is not required anymore.

Description

The TT18-A Stability Enhancer uses ground-breaking fastening technology to significantly increase the stability of spacecraft during the pre-launch phase. While OMB Demolition has been criticized in the past for using "big fancy words for a rocket holder" in their description of their device, none can say the TT18 series doesn't deliver rock-solid clamping action, as advertised. The owner's manual strongly suggests these devices be placed on the bottommost section of the spacecraft, and activated as soon as the engines are lit, for optimal de-clamping performance.
