Which system component helps to minimize engine stall during operation?

The component that plays a significant role in minimizing engine stall during operation is the flame holders. Flame holders are critical in gas turbine engines because they create a stable flame front within the combustion chamber. They achieve this by inducing local turbulence, helping to promote mixing of the fuel and air, and enhancing the ignition process.

By stabilizing the flames during various operating conditions, including low speeds and after rapid throttle changes, flame holders reduce the likelihood of stall, which occurs when the airflow is disrupted and combustion becomes unstable. This stability is vital for maintaining optimal engine performance and preventing damage to the engine that can occur when stalls happen frequently.

In contrast, the oil pump is responsible for lubricating engine components; fuel nozzles provide the necessary fuel for combustion; while throttle linkage controls the engine's power output. Although these components are crucial for overall engine function, they do not directly address the prevention of engine stall. Therefore, the flame holders' role in ensuring stable combustion makes them the key component in minimizing engine stall during gas turbine engine operation.
