Question 162Gas Turbine - Assistant Engineer70% to pass
A pressure stage of an axial-type compressor consists of which of the following?
AI Explanation
The correct answer is A) A set of rotor blades and a set of stator blades.
In an axial-type compressor, a pressure stage consists of a set of rotating rotor blades and a set of stationary stator blades. The rotor blades impart kinetic energy to the airflow, while the stator blades convert the kinetic energy into pressure energy, resulting in the compression of the air. This arrangement of rotor and stator blades is a key feature of an axial-type compressor, making option A the correct answer.
The other options are incorrect because they do not fully describe the components of a pressure stage. Option B refers to the compressor rotor and inlet guide vanes, which are not the primary components of a pressure stage. Options C and D describe only one set of blades, either the stator or the rotor, which is incomplete for a pressure stage.
