Prefixes in Use

General Notes

Diameters

Sizes are given in decimeters; therefore, 2.5m diameter is given as 25. 10m is given as A0, which is 100 in hexadecimal. Radial mounts are given a "diameter" of R.

Typical sizes thus are given as 03, 06, 12, 18, 25, 37, 50, 75, A0.

Parts intended for use in airplanes are sometimes denoted as Mk0, Mk1, Mk2, or Mk3.

Kerbodyne S3 is 37, Kerbodyne S4 is 50.

If an item is two different sizes at the two ends, typically both sizes are given, e.g. 12-25. If an adapter has several mounting plates on one end, the count of these plates is also provided; e.g. 37-25x4.

Magnitude

For volumes and ranges, a prefix of k means that the given number is in thousands, and a prefix of m means the given number is in millions. Note that these are prefixed, so sorting works as expected (e.g. "XX-k03).

Source Designation

For commonly-provided parts (such as fuel tanks), often an abbreviation for the source mod will be added after the part title, in parenthesis; e.g. (RS+).

(Selected) designations thus used:

  • FTP -- Fuel Tanks Plus
  • Kerbonov
  • Mk2+ -- Mk 2 Expansion
  • Mk3+ -- Mk 3 Expansion
  • N-Series -- Near Future Launch Vehicles
  • Orion -- Stockish Project Orion
  • SpaceY
  • SR -- USI Sounding Rockets
  • SSR -- MicroSat
  • RLA -- RLA Reborn
  • RS+ -- ReStock Plus

Pods

RC ("Remote Control") is used as a prefix for probe cores.

Engines

Engines have yet to be thoroughly standardized and thus still use a variety of naming conventions.

If in doubt, you can use:

  • LV ("Liquid Vector") for liquid fuel + oxidizer engines,
  • O (the letter after N, rather than the number) for monopropellant engines,
  • J for jet engines,
  • IX for Ion engines,

The exception is solid rocket boosters, that are named "SRB-diameter-fuel amount".

Tanks

Tanks are named "prefix-diameter-volume 'nice' name".

(Selected) prefixes used:

  • FL ("Fuel Level") -- regular liquid fuel + oxidizer tanks
  • FS -- single-ended liquid fuel + oxidizer tanks
  • FV -- adapter liquid fuel + oxidizer tanks; i.e. tanks that have different diameters top and bottom
  • OL -- for monopropellant tanks
  • Ar -- for Argon tanks
  • Li -- for Lithium tanks
  • Xe -- for Xenon tanks
  • UH -- Holding tanks (for Ore)
  • NL ("Nuclear Liquid") -- liquid fuel only tanks, for use with Nuclear engines
  • YD -- Hydrogen Tanks

Other Parts

  • Adapter -- Adaptor Plates. Multiple sizes are split by a vertical bar, listed from smallest to largest, e.g. "Adapter 50-12|25|37"

  • AE-FF -- Fairings

  • AN -- Nose Cone

  • AV -- Fins and (Basic) Wings. Number is "realive wing area" x 10. (c.f. Wing and XL)

    • AV-B -- basic fins
    • AV-D --
    • AV-R --
    • AV-T --
    • AV-U -- deployable fins, e.g. AIRBRAKES or grid fins

  • C -- Antennas (stock); Number is the antenna class, based on antenna power:

    Class Power Limits Class Limits Class Limits
    C0 5k 0 - 5500 C0+ 5500 - 249k C0++ 249k - 449k
    C1 500k 449k - 549k C1+ 549k - 4.499M
    C2 5M 4.499M - 5.499M C2+ 5.499M - 494M C2++ 494M - 1.996G
    C3 2G 1.996G - 2.004G C3+ 2.004G - 14.96G
