What is "dynamic balancing" in the context of gas turbines?

Dynamic balancing in the context of gas turbines refers to the technique used to reduce vibration in rotating parts. This is critical because excessive vibration can lead to mechanical wear, failure, and reduced efficiency in turbine operation. The process involves adjusting the mass distribution of the rotating components, often by adding or removing material, to ensure that the center of mass aligns with the axis of rotation.

When the rotor is dynamically balanced, it runs smoothly, minimizing vibration levels during operation. This contributes not only to the longevity of the turbine components but also enhances overall operational performance. The other options reflect different aspects of turbine performance and design but do not specifically address the key concern of vibration management that is inherent to dynamic balancing.
