A tweakable Mk16 Parachute

Tweakables are a system added in version 0.23 to set specific properties while in the Vehicle Assembly Building or Space Plane Hangar prior to launch. The major advantage is that these properties are stored with the craft scheme in the building, so they stay the same for every launch.

Properties

The following properties are changeable while building:

  • The percentage of thrust an engine can use (Thrust Limiter).
  • Resource levels of parts which contain them (i.e. liquid fuel tanks), in multiples of 10% of total capacity.
  • Color of active lights (RGB)
  • Whether landing gear begin deployed or retracted when launched.
  • Whether landing gear or wheels can be steered.
  • Whether steerable landing gear or wheels use inverted steering.
  • Altitude at which parachutes fully deploy and minimum air pressure to fully deploy (seen in picture).
  • Whether control surfaces and pivoting winglets are active in pitch, yaw, or roll commands.
  • Whether control surfaces are deployed (as flaps, to increase lift and drag).
  • Whether a flag decal is displayed on parts which support them (i.e. command pods).

Usage

There are a lot of possible usages for tweakables.

  • To provide a more efficient ascent in rockets with solid fuel boosters by lowering the TWR.
  • Store only liquid fuel in some adapters used in aircraft, such as the Mk2 to 1.25m Adapter.
  • Provide empty fuel tanks to be filled in orbit, often used in interplanetary spaceship assembly, or to use fuel tanks as a structural element.
  • Allow fine tuning of thrust during rocket-powered landings, when both tweakables and throttle are used.

Limitations

Although tweakeables give a level of customization not possible before 0.23, some aspects of the spacecraft remain unchangeable for gameplay reasons like changing the thrust limiter for solid rocket boosters during flight. Some tweakables haven't been implemented like changing the output of engine alternators. There is also another technical limitation to tweakables that they only allow certain values. So it's not possible to have a thrust limiting value between 0 % and 5.5 %.
