KSPにおけるStage(ステージ)は同時に作動させるパーツのグループのことである。各ステージには1つ以上のパーツが含まれている。ステージを移行するとそこに含まれるパーツ全てが同時に作動する。エンジンなら点火、パラシュートなら放出、デカップラーなら切り離しが行われる。宇宙船設計において適切なステージ設定は不可欠な作業である。設定ミスによるパーツ誤作動は致命的な事故を引き起こす可能性が高い。ステージは数字の大きいほうから一段ずつ移行していき最終ステージは「0」である。

Setup

The game can automatically set up the stages of a craft, based on the assumption that decouplers serve to separate stages once they are out of fuel or otherwise outlived their usefulness. Whenever a new set of decouplers is placed on a craft, a new stage is created, containing all parts attached to the decoupler. This logic doesn't work for all vessel designs, so it may be necessary to manually reorder parts to the correct stages. This happens by rearranging the icons in the staging process list on the right of the screen in the VAB. Here you can create or delete any number of stages with no restrictions other than that a single stage must remain.

It is also possible reorder parts to different stages on the launch pad or mid flight. However, the staging should mostly be done in the VAB, where there is no pressure of time and it can be saved with the craft.

• Also see controls for manually setting up staging in the VAB/SPH.
• Also see how to activate and modify staging in flight.

ステージ設計手法

ステージの設計には燃料の流れにより主に3つのタイプがある。

シリアル

S2のみ点火してからS1を点火する。

シリアル設計では燃料の交流は無く最もシンプルなステージ設計である。まず外周部のエンジンのみ点火し燃料が尽きるまで燃焼する。燃料切れの外周タンクとエンジンを切り離し、中央エンジンに点火する。切り離しにより中央エンジンに掛かる質量は少なくすることが出来る。

パラレル

All engines are running, but the S1's engine uses the fuel from the S2 engines

This staging is similar to the serial staging, but with the difference that the center stage is running all the time but using the fuel of the radial stages. By this staging type the radial stage will run out of fuel sooner, but when those stages get jettisoned the center tanks are still full. So this type can lift more mass with the same acceleration which could be more effective than the serial staging so you can escape the gravity faster.

アスパラガス

All engines are running and first using S4's fuel then S3's and so on

A more advanced staging type is asparagus staging. The difference to the parallel staging is, that also the radial stages are using the fuel of other radial stages. So all engines will use the fuel of 2 radial engines which deplete very fast. After they run out of fuel those 2 could be jettisoned and the engines use the next 2 radial engines. This repeats until the last radial stage is jettisoned and only the center stage is running. The feature of this type is that after jettisoning a radial stage all remaining tanks are still full so the rocket loses mass more quickly.

Basic Staging Mechanisms

Merging Stages

Decouplers are generally used to separate stages but you can create stages without decouplers in order to -for example- engage solid fuel boosters at just the right time without having to dump anything off your ship to do so. All you have to do is create a stage that contains only the boosters -or other parts you want engaged-. When such a stage is activated the previous stage will be merged into it, the booster now occupying the active stage with all the parts from the previous stage also remaining active. Once used up, the solid boosters can be decoupled by another stage containing only their decouplers leaving the rest of the active stage intact.

Gears, Ladders and Landing Legs

Not all functional parts are influenced by staging. Some of them can be activated and deactivated multiple times even if they are not in the active stage. As of バージョン 0.17.1 these include the LT-2 Landing Strut, Small Gear Bay, Telus Mobility Enhancer and the Telus-LV Bay Mobility Enhancer. These parts serve a purpose that requires repeated activation and as such can be engaged and disengaged at any time.
