Question 129Gas Turbine - Assistant Engineer
70% to passA turbine stage is represented by which of the following components and in which order?
AOne set of rotating blades, one set of stationary vanes.
BOne set of rotating vanes, one set of stationary blades.
CTwo sets of stationary vanes, one set of rotating blades.
DOne set of stationary vanes, one set of rotating blades.
AI Explanation
The correct answer is D) One set of stationary vanes, one set of rotating blades. In a turbine stage, the set of stationary vanes (also called stator blades) directs the flow of the working fluid (e.g., steam or gas) onto the set of rotating blades (also called rotor blades). This configuration allows the energy of the working fluid to be converted into rotational motion, which in turn drives the turbine. The other options are incorrect because they do not accurately represent the components and their arrangement in a turbine stage. For example, option A has the rotating and stationary components reversed, while options B and C include incorrect combinations of rotating and stationary components.
