In the engine module, which component is the Axial Compressor?

• A. Axial Compressor
• B. Gas Generator
• C. Power Turbine
• D. Transmission Shaft and Accessory Gearbox

Answer: (A)

The essential idea is to identify the exact component that performs air compression in an axial-flow path. The Axial Compressor is the device that raises the pressure of incoming air by passing it through multiple rotor and stator stages aligned with the airflow. In the engine module, this component is the one labeled Axial Compressor—the part that does the actual compression before the air reaches the combustor. The Gas Generator refers to the broader subsystem that includes the compressor, combustor, and turbine; it drives the flow but isn’t the axial compressor itself. The Power Turbine uses the expanding gases to generate shaft work, and the Transmission Shaft and Accessory Gearbox handle mechanical power transmission and accessory drive. So the Axial Compressor is the correct choice because it is the specific component responsible for compressing air in the axial flow path.
