…They are broadly divided into electrothermal rockets, electrostatic acceleration rockets, and electromagnetic acceleration rockets. Electrothermal rockets include resistojet rockets, which heat the propellant with an electric heater, and arcjet rockets (also known as arc rockets), which heat the propellant directly with an arc discharge. In both cases, the heated gas is ejected from a nozzle. Unlike electrostatic and electromagnetic acceleration rockets, they are classified as specific impulse rockets because there is a limit to the heating temperature. … *Some of the terminology that refers to "Arc Jet" is listed below.

…種類としては電熱ロケット,静電加速型ロケット,電磁加速型ロケットに大別される。 電熱ロケットには推進材を電熱ヒーターで加熱するレジストジェットと,推進材を直接アーク放電で加熱するアークジェット(いわゆるアークロケット)があるが,いずれも加熱後の気体はノズルから噴射される。加熱温度に限度があるので静電加速型,電磁加速型と異なり比推力型ロケットに分類される。… ※「アークジェット」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
