'''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: [[Parts#Pods|Pods]], [[Parts#Propulsion|Propulsion]], [[Parts#Control|Control]], [[Parts#Structural|Structural]], [[Parts#Aerodynamic|Aerodynamic]], [[Parts#Utility|Utility]], and [[Parts#Science|Science]]. The full game has 168 parts to choose from (as of {{version|0.22.0}}); the latest demo version ({{version|0.18.3|}}) has [[Demo parts|25 parts]].
 
 
 
The parts below are sometimes called '''vanilla parts''', '''default parts''', or '''stock parts''' in order to distinguish them from parts in 3rd-party mods.
 
 
 
== Units of measure ==
 
Ship mass is specified in [[w:Metric tonne|metric tons (t)]], and engine thrust is measured in [[w:Newton (unit)#Common use of kilonewtons in construction|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.
 
 
 
{{Formula|math=\frac{F_T}{W}=\frac{F_T}{m \cdot g_0}|where=* <math>F_T</math> is the thrust obtained from the engine, in [[w:newton (unit)|kilonewton]]s.
 
* <math>W</math> is the [[w:Weight|weight]] of the engine at sea level on Kerbin's surface in kilonewtons.
 
* <math>m</math> is the [[w:Mass|mass]] of the engine in metric tons (t).
 
* <math>g_0</math> 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.
 
 
 
{{Formula|math code=<math>I_{sp} = \frac{T}{\dot m \cdot g_0}, [I_{sp}] = s</math> <span style="padding-right:1em;padding-left:1em;">or</span> <math>I_{sp}= \frac{T}{\dot m}, [I_{sp}] = \frac{m}{s}</math>|where=*<math>I_{sp}</math> is the specific impulse measured in seconds.
 
*<math>T</math> is the thrust obtained from the engine, in [[w:newton (unit)|kilonewton]]s.
 
*<math>\dot m</math> is the [[w:mass flow rate|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).<br><math>\dot m = \frac{\text{Total Mass} - \text{Dry Mass}}{\text{Burn Time}}, [\dot m] = \frac{Mg}{s}</math>
 
*<math>g_0</math> is the acceleration at sea level on [[Kerbin|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 <math>g_0</math> to cancel out this factor.
 
 
 
== Pods ==
 
{{Stats Table Command Pods}}
 
Command pods (aside from the external seat) come with both user accessible [[reaction wheel]], and a [[SAS]] module.
 
 
 
== Propulsion ==
 
{{:Parts/Propulsion}}
 
 
 
== Control ==
 
{{:Parts/Command & Control}}
 
 
 
== Structural ==
 
{{:Parts/Structural}}
 
 
 
== Aerodynamic ==
 
{{:Parts/Aerodynamic}}
 
 
 
== Utility ==
 
{{:Parts/Utility}}
 
 
 
== Наука ==
