Compressor type used in gas turbines: identify the rotary compressor Gas turbines (especially aircraft and large power units) primarily use which type of rotary compressor? Choose the correct option.

Difficulty: Easy

Centrifugal type
Axial-flow type
Radial-flow type
None of these

Correct Answer: Axial-flow type

Explanation:

Concept/Approach
Modern aircraft and heavy-duty gas turbines predominantly use axial-flow compressors for their high mass-flow capability and good efficiency at high pressure ratios via multistaging. (Small/industrial units may use centrifugal stages, but axial flow is the standard for large engines.)

Final Answer
Axial-flow type

How compressor capacity is expressed: choose the standard unit Compressor capacity is normally stated as a volumetric flow rate at standard (or specified) conditions. Select the correct unit.
Axial-flow compressor operating regime: statement on best performance Statement: An axial compressor gives its optimum performance at high rotational speeds and large volume flows. Decide whether the statement is correct.
Effect of large clearance volume in a reciprocating compressor If the clearance volume of a reciprocating compressor is large, what is the primary effect on delivered flow? Choose the correct outcome.
Gas-turbine intercooling: effect on net work and thermal efficiency. Consider a simple gas turbine where intercooling is applied only between multistage compressors (no reheat and no recuperator). Assume the same compressor pressure ratio, the same turbine inlet temperature, and ideal intercooling to the initial compressor inlet temperature. Choose the correct combined effect on plant performance.
Rotary compressors: suitability for flow rate and pressure level. Evaluate the statement about application range: rotary compressors are preferred when a large volume flow is needed at relatively low delivery pressure. Decide if this statement is correct or incorrect.
Compressor definitions: identify the correct efficiency term. Definition target: the ratio of free air delivery (at standard condition) per stroke to the piston's swept volume. Select the correct name of this ratio.
