A three-stage rocket featuring various default parts (in 0.18.4)
Part icon.png

Parts are the basic assembly items for rocket and space plane construction in Kerbal Space Program. As a whole, they compose the building materials the player can choose from in the Vehicle Assembly Building and Space Plane Hangar. Parts are split up into seven major categories: Pods, Fuel Tanks, Engines, Command and Control, Structural, Aerodynamic, Utility, and Science. The full game has 227 parts to choose from (as of version 0.90); the latest demo version (0.18.3) has 24 parts.

The parts below are sometimes called vanilla parts, default parts, or stock parts in order to distinguish them from parts in mods.

The parts in the game generally resemble those of the American Space Program (NASA) during the 1950s-1970s, for instance, the Mk1-2 Command Pod resembles the Apollo Command Module, the Mk1 Command Pod resembles the Mercury Capsule, and many LV-series engines resemble American-built rocket parts. Kerbodyne rocket parts are virtually indistinguishable from real NASA rocket parts.

Units of measure

Ship mass is specified in metric tons (t), and engine thrust is measured in kilonewtons (kN).

The amount of resources counted in units, not marked in the game, but these units are differ by the kind of resource! These different resource units marked with different signs in the tables.

The special signs of the tables and their meaning:

  • Crew : used to sign the number of crew members. Means one kerbonaut.
  • Fund : the mark of the monetary unit of the Kerbals.
  • units of fuel : represents the unit for fuel (liquid fuel, oxidizer, monopropellant and solid fuel), as a volume means 2-2.5 liters.see here
  • Xenon unit : represents the unit for liquidized gas, in case of xenon means 0.1 kg of liquidized gas.
  • Air unit : represents the unit for intake air. One unit is equal with 5 kg intake air. The actual volume of air will depend on the atmospheric pressure. At sea level of Kerbin 3.8 m³ contains this amount, but in the upper atmosphere several hundred cubic meters are needed for this much air.
  •  : represents the unit for electric charge. As estimated from the capacity batteries and the consumers, it is about 10 kJ (power of 10 kW for a second).
  • Mit(s) : Measure of data, produced by experiments. There is no limit on the amount of data which can be stored.

There are some properties whose meanings may be unclear:

Tolerance, Impact tolerance 
The maximum speed (measured in m/s) at which the part can survive a collision with a rigid surface (for instance the surface of a celestial body). In a collision at a higher speed, the part will be destroyed.
Max. Temp. 
The maximum temperature the part can survive; above this temperature the part will be destroyed.
Drag 
The drag coefficient and not actually the drag in newtons applied to it.

Thrust-to-weight ratio

→ Main article: Thrust-to-weight ratio

The thrust-to-weight ratio (TWR) at sea level on Kerbin is calculated by the following equation, which applies only to rockets, because jets use a complicated formula for the lift on a vehicle to vehicle basis.

{\frac  {F_{T}}{W}}={\frac  {F_{T}}{m\cdot g_{0}}}
Where:
  • F_{T} is the thrust obtained from the engine, in kilonewtons.
  • W is the weight of the engine at sea level on Kerbin's surface in kilonewtons.
  • m is the mass of the engine in metric tons (t).
  • g_{0} is the acceleration at sea level on Kerbin's surface: 9.81 m/s².

This TWR applies only on Kerbin's surface. At other locations the weight differs because the gravitational acceleration is different.

Specific impulse

→ Main article: Specific impulse

The specific impulse at is calculated by the following equation. To reduce confusion about the unit of measurement, specific impulse could be given in velocity or time units. In game the specific impulse is specified in seconds.

I_{{sp}}={\frac  {T}{{\dot  m}\cdot g_{0}}},[I_{{sp}}]=s or I_{{sp}}={\frac  {T}{{\dot  m}}},[I_{{sp}}]={\frac  {m}{s}}
Where:
  • I_{{sp}} is the specific impulse measured in seconds.
  • T is the thrust obtained from the engine, in kilonewtons.
  • {\dot  m} is the mass flow rate in Mg/s, which is negative the time-rate of change of the vehicle's mass since propellant is being expelled. The total and dry mass are given in megagrams (metric tons, t).
    {\dot  m}={\frac  {{\text{Total Mass}}-{\text{Dry Mass}}}{{\text{Burn Time}}}},[{\dot  m}]={\frac  {Mg}{s}}
  • g_{0} is the acceleration at sea level on Kerbin's surface: 9.81 m/s².

The gravitational acceleration at sea level is only a conversion factor between the velocity and time unit. Because of this it won't change when the craft is not at Kerbin's surface. To convert the specific impulse from a time unit into a velocity unit multiply it with g_{0} to cancel out this factor.

Tables of Parts

In the tables are the main properties of the parts. In most cases the tables follows the categorization structure of the game. In case of deviation, the position in part board of the game is noted. Some parts have been made physicsless to improve performance in the game from version 0.23 onwards. These parts behave as if they have no mass and cause no drag, unless they become the root part of a vessel.

Many parts have some resource storing capacity, which makes the mass and the cost different in full and empty state. In this case the full is shown as normal, and the empty values are in round brackets under the full values. Some properties, like the entry cost, are not included, but can be found in the part-box on right side of the part's page.
