Accelerating the compressor to the self sustaining speed of the engine is the function of which of the following components?

Correct Answer: Option B — Starter

A gas turbine cannot self-start because the compressor must reach a minimum speed to provide sufficient airflow for combustion. The starter motor provides the initial torque to accelerate the compressor rotor to this self-sustaining speed, at which point the engine can maintain combustion and accelerate under its own power.
