Rotating blade - Rotating blade

Japanese: 回転羽根 - かいてんばね
Rotating blade - Rotating blade

...Steam turbines do not have much torque, but they can produce a lot of power by rotating at high speeds. This characteristic made them ideal as prime movers for driving generators, and their development coincided with the beginning of the use of electricity and the expansion of demand for it.
[Operating principle and format]
The basic components of a steam turbine are the nozzle, which expands the steam into a high-velocity stream, and the rotor blades, which do the work. This set is called a pressure stage, or simply a stage, and is essentially represented in Figure 1. Large turbines consist of many stages.

*Some of the terminology that refers to "rotating blades" is listed below.

Japanese:

…蒸気タービンはトルクはあまり大きくないが,高回転数とすることにより大きい出力を出せるという特徴をもっており,この特徴が発電機駆動用原動機としてうってつけのものであったため,その進歩はまさに電力使用の始まりとその需要の拡大と軌を一にしている。
[作動原理と形式]
 蒸気タービンの基本構成要素は,蒸気を膨張させて高速気流とするノズルと,仕事を行う回転羽根であり,この1組を圧力段,あるいは単に段と呼び,本質的には図1で代表される。大型タービンは多数の段から構成される。…
