A three-stage rocket featuring various default parts (in 0.18.4)

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, Propulsion, Control, Structural, Aerodynamic, Utility, and Science. The full game has 184 parts to choose from (as of version 0.24); 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 third-party 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).

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.
